[car home New Energy] In the eyes of enthusiasts and technology controllers, the new energy vehicle is more like a work of art, and every core component is its essence. When talking about pure electric vehicles, they will ask you about battery manufacturers or battery suppliers, which can be regarded as the second brand of vehicles; When it comes to hybrid cars, they will ask you "P". What do these slang words mean? Today, I will talk to you about different types of motor architectures for hybrid vehicles.

　　At present, the application modes of motor architecture in the industry are different, and the specific applications and explanations under different architectures are also slightly different. The starting point of this paper is to sort out the basic principles and application modes of p0-p4 architecture and the purpose of different combination schemes.

● Definition and analysis of P0-P4 motor

　　In hybrid electric vehicles, it can be divided into P0-P4 and Ps architectures according to the different motor Positions, where P stands for motor position, and the motors in different positions play different roles, which are directly related to vehicle energy consumption and power performance. Which hybrid electric vehicle is more suitable for you?

◆P0 architecture: simple structure and early fame.　

　　The motor with P0 structure is installed at the front end of the engine, which is connected with the crankshaft of the engine through a belt. The vehicle equipped with P0 motor can drive the mechanical compressor of the air conditioner to run when the engine stops at the traffic lights, so as to realize engine start and stop, braking energy recovery and power generation, and auxiliary power output.

"Bosch 48V MHEV System"

　　The technology and structure of P0 architecture are relatively simple and widely used. The automatic start-stop system that many drivers and friends shut down when they get on the bus is a typical P0 architecture, and the history of automatic start-stop can be traced back to 1970s. Compared with vehicles equipped with automatic start-stop function, P0 architecture adopts BSG (belt-driven starter/generator; Belt-driven starter/generator) motor, and equipped with a larger battery, can be competent to drive the compressor and auxiliary engine.

　　When the engine is stopped, P0 motor can drive the air conditioner compressor to work independently, thus reducing the idle time of the engine; When the vehicle starts or accelerates, P0 motor can assist the engine to run, help the engine quickly get rid of the inefficient working range, save fuel and effectively improve the driving quality. Because P0 motor transmits power to the wheels in series, the motor can’t drive the wheels independently without the engine, so there is no pure electric driving mode. In addition, the P0 motor is flexibly connected with the crankshaft through a belt, so the ceiling for applying force to the engine and recovering kinetic energy power is low.

"2020 modified Mazda CX-5 2.5L automatic four-wheel drive smart model"

　　Audi SQ7 TDI and Mazda i-Eloop belong to P0 architecture. Because P0 architecture has low transmission efficiency and the motor can’t directly drive the wheels, P0 motor usually appears as an auxiliary in the field of new energy vehicles. There will be corresponding analysis and cases in the following.

◆P1 architecture: independently developed/highly integrated.

　　P1-based motor is located at the rear end of the engine crankshaft, which replaces the traditional flywheel. Besides inheriting the function of flywheel to store energy and inertia outside the engine power stroke, P1-based motor has similar functions as P0-based motor, and also supports engine start and stop, braking energy recovery and power generation, and auxiliary power output.

Honda IMA hybrid system

　　Compared with P0 architecture, P1 architecture is more compact, and its motor is integrated in the engine housing. The design needs to consider the volume of the engine and the layout in the engine room. Because different gearboxes need corresponding design schemes, the research and development and manufacturing costs of P1 motor are relatively high. Existence is reasonable, and high investment often corresponds to high return. The engine crankshaft acts as the rotor of P1 motor, which has higher power transmission efficiency, better fuel saving effect and more obvious improvement on driving performance. In addition, P1 motor can apply auxiliary braking torque through electromagnetic field adjustment on downhill section to improve safety.

　　Although they are in different positions, P0 and P1 are connected with the same disease. As long as the motor rotates, the engine crankshaft must rotate, so the motor can’t drive the wheels alone, and there is no pure electric driving mode. In the kinetic energy recovery and sliding mode, the kinetic energy is wasted because the crankshaft must be driven to idle, and the noise and vibration are also increased because of the internal combustion engine following.

"Mercedes M254 Engine"

"2020 Mercedes-Benz E-Class (imported)"

　　A few days ago, the E350 model launched by Mercedes-Benz overseas adopted a 2.0T 4-cylinder engine code-named M254, and added 48V light mixing technology in the electrification transformation process. The ISG motor equipped with it has a maximum power of 12kW and a peak torque of 180N·m, which alleviates the performance of turbine lag when the wheels start and accelerate. This system is a typical P1 architecture. Officially, the motor is named "FAME" (modular engine). Some foreign media have speculated that this motor will appear on other PHEV models.

◆P2 architecture: modular design/strong fuel economy and wide application.　

　　The P2-frame motor is located between the engine and the gearbox. Because it is not necessary to be integrated in the engine housing like P1 motor, the layout can be more flexible. The structure can be equipped with 1-2 clutches between the engine and the gearbox, which can be divided into three layout modes: ① Single-clutch structure in which the motor is arranged in front of the clutch, and the motor plays the role of assisting, parking power generation and starting the engine, which is similar to P1 structure; (2) Single-clutch structure in which the motor is arranged behind the clutch, so that the motor can drive the vehicle independently, recover braking energy, generate electricity and assist; ③ The motor is arranged in the middle of the dual clutch structure, so that the motor can drive the vehicle independently, and can also start the engine or park for power generation.

　　P2 architecture has strong compatibility and can be matched with all gearboxes (including manual gearboxes). P2 architecture is widely used in hybrid vehicles at present, and many parts suppliers have mature solutions. Take Borgwarner’s P2 motor module as an example. It integrates a dual-mass flywheel and an engine release clutch, which can disconnect the clutch and the motor direct-drive vehicle. It can convert an internal combustion engine-powered vehicle into a hybrid vehicle without changing the engine and gearbox, which means that car companies can expand the power combination of vehicles and enrich the product line of hybrid vehicles with less investment, shorter time and greater flexibility.

"Audi A3 e-tron Power System"

"2017 Audi A3 new energy (imported) Sportback e-tron comfort type"

　　Audi A3 e-tron is a representative model with P2 architecture. It is equipped with a 1.4T engine and a permanent magnet synchronous motor with a maximum power of 75kW. The battery capacity of the car is 8.8kWh, and the pure electric cruising range is 50km under NEDC condition.

◆P3 architecture: efficient power transmission and large space occupation.　

　　The P3-frame motor is located at the output end of the gearbox, and its pure electric drive and kinetic energy recovery efficiency are high, and the effect of rapid acceleration is very direct. In terms of function, P3 motor can realize braking energy recovery and pure electric drive vehicles. Because the motor can’t be integrated with the gearbox or engine, it needs to occupy extra volume, so P3 architecture is more suitable for rear-wheel drive, and there is enough space for layout.

　　Compared with P0, P1 and P2 architectures, P3 architecture’s power transmission path does not pass through the gearbox, so the efficiency of pure electric drive and braking energy recovery is higher, and at the same time, the working time of the gearbox is reduced, which is helpful to prolong its service life. But the problem is also obvious, P3 motor can’t realize parking charging, and the shortcomings of outdoor camping and other use scenarios are exposed.

　　The representative model is BYD Qin PHEV, which is a parallel hybrid car with P3 motor as the core. With the original large-capacity battery setting, it not only meets China’s pure electric endurance of 50km for PHEV, but also can stack the performance of engine and motor to achieve stronger power output.

◆P4 architecture: realize four-wheel drive.

　　P4 frame motor and engine do not drive the same shaft, thus helping the vehicle to realize four-wheel drive. It can be a motor that drives the front axle/rear axle, or it can simply cancel the axle just like Acura NSX, and directly use two hub motors to drive the wheels. P4 architecture is similar to P3 in function, which can realize braking energy recovery and pure electric drive vehicles.

"2020 BMW i8 Extreme Night Meteor Limited Edition"

　　P4 architecture is mostly used in plug-in hybrid vehicles, and sports cars are more commonly used, such as porsche 918 Spyder, Acura NSX, BMW i8 and other sports cars. Take BMW i8 as an example. This 1.5T three-cylinder engine squeezes out the maximum power of 231Ps and the maximum torque of 320 N m. The maximum power of the permanent magnet synchronous motor on the front axle is 131Ps and the peak torque is 250 N m. It is equipped with a two-speed automatic gearbox to adjust the torque. The official acceleration time of 0-100km/h is 4.6s, which brings excellent power and can effectively reduce fuel consumption.

◆Ps architecture: parasites of double clutch

　　P3 motor is coupled at the output end of the gearbox, and Ps motor is directly integrated inside the gearbox. Because of the close location distribution, Ps architecture is easily confused as P3 architecture. Ps architecture is based on dual-clutch gearbox, which uses the characteristics of dual-clutch gearbox with two input shafts to integrate the motor on one of the shafts, and can realize pure electric drive vehicle and braking energy recovery.

"PS architecture power transmission mode"

　　The motor, clutch and reducer of Ps structure are put into the same shell, which is more fuel-efficient and smoother. But the disadvantages are also obvious, because the even shaft of the dual-clutch gearbox bears more torque than the odd shaft, which will lead to the inconsistency between the two shafts and the clutch wear; In addition, the integration of the motor into the gearbox will increase the maintenance cost, because it is the gearbox assembly that needs to be disassembled regardless of gearbox failure or motor failure.

"2021 Borui New Energy 1.5T ePro Leading Edition"

　　At present, among China brand car companies, Great Wall, Chery and Geely are all studying DHT gearbox, which is the cornerstone of Ps architecture. Taking Geely Automobile as an example, the 1.5T+7DCTH plug-in hybrid system of Geely ePro family models has the characteristics of high motor efficiency and high powertrain matching, and has the comprehensive advantages of high efficiency, excellent space and good quality (high cost performance). Among them, the efficiency of Ps frame motor is 97%, which is about 2% higher than that of P2 coaxial motor. The working speed of Ps frame motor is not limited by the engine, and the engine and motor can work in the high efficiency area at the same time, which can effectively reduce the fuel consumption of the whole vehicle.

●Combined frame motor

　　Brothers in battle, fathers and sons in battle, and motors with a single architecture all have shortcomings more or less, so combining two or more architectures of motors becomes the best solution at present. On P3 or P4 frame vehicles, it is necessary to install another motor for the engine in order to perform the engine start-stop and power generation functions, so many hybrid vehicles have two motors, forming a combined configuration of Px+Py. For example, WEY P8 has a BSG motor at the front end of the engine and a permanent magnet synchronous motor at the rear axle, which belongs to P0+P4 configuration. Let’s understand the technical characteristics of the combined structure motor through the development of domestic and foreign car companies and the analysis of car models.

◆ Volvo PHEV Technology Review and T8 Powertrain Analysis

　　In 2013, Volvo’s first-generation plug-in hybrid (PHEV) technology was applied to S60 PHEV models, adopting P0+P4 architecture, consisting of a BSG motor with 15kW engine front-end power and a 50kW permanent magnet synchronous motor with rear drive axle; In 2015, Volvo’s second-generation PHEV technology was applied to XC90 PHEV models, adopting P1+P4 architecture, consisting of an ISG motor with a power of 35kW and a permanent magnet synchronous motor with a rear drive axle of 60kW; At present, Volvo adopts the third generation PHEV technology based on CMA vehicle platform, and adopts a hybrid powertrain composed of an engine matching P2 motor.

　　As for the specific vehicle type, Volvo XC90 PHEV adopts a hybrid powertrain with P1+P4 architecture. The front axle of the vehicle is equipped with a gearbox integrated motor named C-ISG (Crank-integrated starter generator), which has three functions of start-stop control, power generation and assistance, and the rear axle is also equipped with a motor with the maximum power of 65kW. At present, Volvo’s PHEV models cover cars, station wagons and SUVs, all of which use modular PHEV powertrains.

◆ Evolution history of BYD DM system and analysis of the third generation DM system.

　　Since 2008, BYD’s DM system (Dual Mode system) has been upgraded twice. At present, the upgrade of the plug-in hybrid of the third generation DM is not only in terms of power, but also in terms of "performance" attributes of the whole BYD model after the "542" plan was put forward from the second generation DM system.

　　"High power consumption" is an obvious problem in the second-generation DM system. BYD thinks that BSG motor+electronic control system can solve the problem of "avoiding the inefficient area of the engine", assist the vehicle to generate electricity, make the whole energy flow system more balanced, and bring better acceleration performance, so the brand-new "BSG architecture" system is one of the core upgrades of this generation DM3.

　　The biggest purpose of BSG motor of the third generation DM system is not only to provide start-stop function servo for the engine, but also to charge the power battery while driving, and it can also be used to improve the acceleration performance. When the vehicle is driving in the all-electric drive mode, when the engine is involved, the BSG motor will drive the engine to start, so as to reduce the shock and assist in gear shifting.

Full text summary：

　　With the stricter emission standards and the support policies for new energy vehicles, OEMs pay more and more attention to the new energy market. Compared with the development of a brand-new hybrid system, the P2 technical route with modular design does not need to change the existing structure, is easy to integrate and is suitable for matching all gearboxes. Even if the fuel saving effect is not as good as that of parallel connection, the fuel consumption can be reduced at a lower cost, which has become a "shortcut" for many car companies.

Recently, many netizens left a message saying, "I have 200,000 in my hand, and I have been hesitant to buy it. I wonder if this car is good?" Therefore, this issue of Xiaobian will take you through the real feelings of some car owners and comprehensively analyze the advantages and disadvantages of this car. After reading it, maybe you will know it!

Let’s talk about it firstadvantage：1.Mature technology, equipped with series, has good power output and economical fuel economy. Equipped with a 2.0T 4 cylinder,220Horse, the peak value is 350, whether it is the acceleration of urban roads, overtaking or long-distance driving on highways, it can be handled with ease.

2.The design conforms to the aesthetics of young consumers.The classic appearance is calm and atmospheric, with a very business sense, suitable for formal occasions, and young and athletic, catering to the aesthetic needs of young consumers and broadening the consumer groups.

3.The interior has good texture.The interior is made of high-quality materials, the interior is spacious, the comfort and wrapping of the seat are excellent, and the material texture of the center console and other parts is good, which improves the overall texture of the car.

Equipped withLarge sizeThe central control screen, full LCD instrument panel and W-HUD head-up display are clear and informative, which is convenient for drivers to obtain vehicle information.

4.The hedge ratio is high.As a well-known medium-sized car, its value-keeping rate in the used car market has been relatively low.highLevel, which means that in the future, if the owner wants to change cars, the vehicle can have greater residual value.

Next, let’s talk about the disadvantages: 1.Gearbox problemAlthough the seven-speed dual-clutch gearbox performs well at high speed, it has obvious frustration when driving at low speed, especially when switching from first gear to second gear, which affects the smoothness and comfort of driving date.

2.Limited functionCompared with some intelligent car systems at the same level, there are many shortcomings in the expansibility of entertainment, navigation and other functions.

3.There are many plastic parts.More plastic parts are used in some parts of the car, which reduces the texture of the interior to a certain extent, and in hot summer, plastic parts may have some unpleasant smells.

The above are the real feelings and experiences shared by many car owners in Passat at present, as well as some opinions of Xiaobian! Generally speaking, this car has certain advantages compared with the cars of the same class, whether for daily travel or daily ride! If you have different views or opinions, welcome to discuss and leave a message in the comment area!

　　　　Some people joked that "lazy people create the world", and lazy people invented cars in order to walk less and get to their destination quickly; In order to reduce the fatigue of frequent gear shifting during starting and stopping, the automatic gear was invented, and so on. In fact, the "lazy people" who build cars have long seen the sufferings of drivers, so they invented the automatic parking system to get people who are afraid of parking out of their misery.

　　　　Volkswagen has always been a pioneer in leading the development of automotive technology. The new generation of Magotan has made people see the embryonic form of smart cars. ACC active cruise system, lane departure assistance system and automatic parking system are all equipped with the new Magotan. Today, we mainly analyze its latest automatic parking system.

　　　　Volkswagen’s automatic parking system has gone through three generations, from a fool system that can only park sideways, and now it is finally powerful enough to park in almost any way.

　　　　In addition to the parallel parking supported by the first generation system, this generation of parking assistance system on the new Magotan can also support vertical parking and realize parking at a certain angle, as well as parking in ultra-small parking spaces (60 cm smaller than that of the first generation), parking in corners, parking on the edge of roads and parking between other obstacles. In addition, when the space in front of the car is at least 50 cm, it can also support leaving the parking space. The parking assistance system is equipped with 12 detectors (front 4, rear 4, right 2 and left 2), which can be activated by the center console button when the speed is less than 40 kilometers. Turn on the turn signal on one side to indicate that the car is parked on that side of the road. When the system detects a large enough parking space, then it can start auxiliary parking. Put into reverse gear, then control acceleration and deceleration, and the multimedia display will be assisted by sound and image signals. It can be said to be the most advanced automatic parking system at present.

　　　　Of course, high technology must be used correctly. Here, I will teach you how to apply this high technology slowly, so that parking is no longer a problem.

　　　　Side parking method:

　　　　When you arrive at your destination to find a parking space, press the auto parking button. When the parking space is not higher than 40 km/h, the system detects a suitable parking space and reaches the initial position, then you can start auto parking.

　　　　Stop after finding the position, then put into R gear, release the steering wheel with both hands, and automatic parking will begin. Use the brakes to control the speed, at which time the vehicle will automatically turn and reverse. As long as you pay attention, the driver needs to judge the distance between the front and rear cars through the prompt sound of the radar and the icon of the central display screen. When the car can’t be parked in the parking space at one time, the radar and the display screen will tell you that you need to step on the brake to park, and then put it into the D gear. Similarly, the brake is used to control the speed, and the car will automatically move forward in the direction until the system automatically parks the car in the parking space in parallel, and the display screen on the dashboard will prompt that the automatic parking is completed.

　　　　The new Magotan’s one-button automatic parking is very simple, that is, after pressing the automatic parking button, the car will automatically find the parking space by radar, and when it is found, it will stop and put it into reverse gear. At this time, you can only control the brakes with your right foot. The engine fuel injection and steering wheel steering are completely automatic, and if it cannot enter at one time, the position can be rubbed.

　　　　It should be noted that the driver should not intervene in the steering wheel during automatic parking. Once you move the steering wheel, automatic parking will be terminated. Once it is terminated, you must re-check the berth before you can start automatic parking again.

　　　　Believe in technology, even if you are an old driver, radar will definitely be much more accurate than your feelings.

　　　　Vertical parking method:

　　　　After learning parallel automatic parking, vertical parking is a principle.

　　　　The automatic parking function is also turned on, and the system automatically detects the parking space. When it reaches the starting position, stop, put into R gear, use the brake to control the speed, and leave the rest to the computer.

　　　　Vertical automatic parking can also make multiple displacements until the vehicle completely enters the parking space.

　　　　Parallel parking method:

　　　　In order to enter the mode of driving out of the parallel berth, the vehicle must not start driving after ignition, that is, the position of the vehicle before the engine starts cannot be changed. .

　　　　Press the automatic parking button, and the indicator lights up to indicate that the function has been activated. A prompt will appear on the driving computer: "Please turn on the turn signal and put it into reverse gear".

　　　　Turn on the turn signal when the vehicle is stationary, put it into reverse gear and start, and the system will start to assist the vehicle to automatically drive out of the berth. The direction of the turn signal tells the system which direction the driver should drive out of the berth.

　　　　Next, you can follow the same prompts of the driving computer as when driving into the berth. After the system has moved back and forth several times, the driver will take over the steering wheel.

　　　　Summary:

　　　　At present, the automatic parking of Volkswagen’s new Magotan is realized by the cooperation of multiple systems, EPS electric power steering, ESP electronic stability program, engine and gearbox management, instrument cluster, electronic steering column, etc. It can be said that it is the most advanced and mature automatic parking system, which only needs one button, and the rest is done by computer.

　　　　But no matter how advanced the system is, it is not omnipotent at all times. For example, in the process of automatic parking, pedestrians or vehicles suddenly appear in the rear. After the radar detects possible dangers instantly, it will automatically brake immediately to minimize losses. This is actually the best way to protect vehicles.

　　　　I believe that with the continuous progress of science and technology, autonomous driving will appear in production cars sooner or later, but now, the automatic parking of the new Magotan can completely make you a parking expert.

[ITBEAR] Tesla’s new global spy photos are frequent, and many innovations have sparked heated discussions.

Recently, the test vehicles of Tesla’s new Model Y have been frequently exposed in many places around the world, which has aroused widespread concern. Since it was first photographed in China, there have been at least five batches of spy photos of the new Model Y. From these spy photos, we can see many important changes in the new car.

In terms of body structure, the new Model Y continues Tesla’s consistent short front suspension and long rear suspension design, and the axle ratio is about 3 times. The front and rear parts have been significantly adjusted, and the shape and internal structure of the front and rear headlights have also changed. The design of split headlights has become a high probability event. Technical analysis shows that the new headlights may adapt to Tesla’s FSD projection technology. The changes in the car directly moved the new design of Huan, including canceling the gear shifting mechanism and the turn signal lever, setting the star-ring atmosphere light on the door panel, increasing the ventilation function of the seat, and still using a lot of environmentally friendly materials in the interior.

In the external shape, the camouflage layer of the new Model Y is mainly concentrated in the front and rear, and the exterior rearview mirror, door panel, wheel hub size and other parts have been unveiled. Combined with the spy photos exposed in Spain, the front bumper of the new Model Y has been redesigned, with the front main beam lowered, the front cover flatter and the raised ribs added. The style of the front shovel is close to the high-performance version of Model 3, the Y0 line has no inflection point treatment, the wind impact area is weakened, and the streamlined design is more prominent. Newly designed low wind resistance wheels may also appear, further reducing the wind resistance coefficient.

The new Model Y also adds an electric tail, and the through taillights are also confirmed. The electric tail optimizes the air flow of the vehicle during driving from the aerodynamic point of view, improves the wind resistance and enhances the dynamic stability, which is helpful to improve the acceleration and extreme speed performance. The safety mentioned by Tesla in the latest OTA version and the brand-new cover design make people speculate that the new car may have added a pedestrian protection device for the cover.

Inside the cockpit, in addition to the known changes, the voice control system of the new Model Y will also be optimized to support voice wake-up function. The new car may be equipped with a cockpit chip with stronger performance and better adaptability to HW4.0. The version of MCU 2.0 delivered early in China uses Intel ATOM processor, while MCU 3.0 is switched to AMD Ryzen, which greatly improves its performance. Therefore, the possibility that the new Model Y will update MCU 4.0 is not ruled out.

In terms of battery and battery life, the new Model Y is expected to be equipped with a 95kWh large-capacity battery pack with a fast charging power of 350kW. If the news is true, this will be the battery pack with the largest equipment capacity in Model Y’s history. However, because the current Model Y uses the 2170 ternary lithium cylindrical battery provided by LG, it is quite challenging to pack the large battery pack without changing the chassis. Therefore, the new Model Y may adopt Contemporary Amperex Technology Co., Limited Shenxing Battery PLUS to solve the problem of getting a large-capacity battery on the bus and optimize the fast charging efficiency.

In terms of chassis suspension, the new Model Y will be further optimized. The combination of the front double wishbone and the rear five-bar linkage belongs to the control player in the era of fuel vehicles, but too strong support may lead to a hard chassis. Tesla has slightly optimized the domestic Model Y, but the effect still does not fully meet the comfort expectations of the owners. Therefore, the new Model Y may adopt an adaptive damping suspension, adjust the damping valve through the chassis sensing hardware, and change the damping force at any time by using the hydraulic principle, thus adapting to various road conditions.

　　On the afternoon of January 26th, Li Keqiang, Premier of the State Council of the People’s Republic of China hosted a forum to listen to the opinions and suggestions of experts, scholars and business people on the Government Work Report.

　　On the afternoon of January 26th, Li Keqiang, Premier of the State Council of the People’s Republic of China hosted a forum to listen to the opinions and suggestions of experts, scholars and business people on the Government Work Report.　

　　Beijing, January 27th (Reporter Feng Yue) According to the Voice of China News and Newspaper Summary, Li Keqiang, Premier of the State Council of the People’s Republic of China hosted a forum yesterday to listen to the opinions and suggestions of experts, scholars and business people on the Government Work Report. The State Council Vice Premier Zhang Gaoli attended the forum.

　　At the symposium, experts and scholars from universities, scientific research institutions and financial institutions expressed their opinions on the current economic situation. Business leaders from the Internet, electronic information, venture capital, building materials and other industries discussed their views on industry development and economic trends respectively. Li Keqiang said: "While stabilizing macro-policies, we focus on interval control and directional control. In fact, in the past two years, the most important indicator we have adopted is to stick to the employment rate. We are most pleased that employment has increased by 13 million people, which is very important for a developing country. "

　　Faced with the current slowdown in growth and difficulties in the operation of some enterprises, experts suggest that structural reforms should be used to solve structural contradictions, and high-end industries such as modern service industries should be developed to improve economic efficiency. Li Keqiang said: "When we enter the new normal, we can’t pursue higher speed, but we should put more energy into improving quality and efficiency. We talk about a stable macroeconomic policy to ensure that in a reasonable range, we always grasp it in this process and use more energy to promote comprehensive deepening reforms and promote structural reforms. "

　　Tsinghua University, Wu Xiaoling and others proposed to implement a moderately tight monetary policy, accelerate financial reform and stabilize market expectations. Li Keqiang said: "What Comrade Wu Xiaoling said gives us a good inspiration. We always talk about relaxing access to finance on the one hand and strengthening supervision on the other. In fact, many aspects of our financial supervision are unnecessary or even should not be. In this respect, it just hinders market access. Our government has to do the government’s business. We always give orders to the market and always take enterprises to plan, but the government has done nothing of its own. Think about it, some of what we say should not be, some may be empty talk, and it may be meaningful to give a signal at most. The operation of enterprises should be planned by themselves, so we should concentrate on doing the government’s things well. "

　　At the symposium, several entrepreneurs put forward suggestions on encouraging innovation, developing venture finance, promoting enterprises to "go global" and reforming state-owned enterprises. Li Keqiang emphasized: "How can we let the masses start businesses and innovate? I think this is a new engine of China economy. If 120 million people can start businesses and innovate, what changes will this bring to our entire economic structure? If we say that in the first 30 years (reform and opening up), we relied more on hard work, and then we should rely more on wisdom, relying on the government to simplify administration and decentralize power, lowering the market entry threshold, so that people who are willing to start businesses can start businesses, and then strengthen supervision after the event in the market. If we say that mass entrepreneurship and innovation are mobilized, this requires government reform. "

In automobile maintenance, the fuel filter is often neglected, but its importance to the engine cannot be underestimated. Many car owners wonder: Do you want to replace this seemingly inconspicuous part? Let’s discuss this problem in depth together.

The function of fuel filter is to filter impurities in gasoline and ensure that the fuel entering the engine is clean and pure. With the increase of service time, the filter will be blocked gradually, which will affect the fuel supply and eventually lead to the decline of engine performance. Therefore, it is not only necessary to change the fuel filter regularly, but also very important to maintain the car.

First, the hazards of filter clogging

If the fuel filter is not replaced for a long time, it will lead to insufficient oil supply for the engine and cause many negative effects. First of all, the engine power is obviously reduced, and the acceleration is weak, especially when climbing or overtaking. Secondly, the fuel consumption will increase significantly, and the same journey may consume 10%-20% more fuel. More seriously, the fuel system may be damaged and the repair cost is high.

Some car owners reported that their car failed to change the fuel filter for three years, which led to the engine failure light, and the repair cost exceeded 5,000 yuan. This lesson tells us that a small maintenance negligence may bring huge economic losses.

Second, the replacement cycle and cost

Generally speaking, the replacement period of fuel filter is 30,000-50,000 kilometers or 2-3 years, depending on the vehicle type and the use environment. High-end models may have a longer service life, and in areas with poor air quality, they may need to be replaced more frequently.

The cost of replacing the fuel filter is not high, usually between 100-500 yuan. Compared with the possible engine damage, this investment is insignificant. Some car owners said that after changing the filter regularly, they obviously felt that the car had more power and reduced fuel consumption, saving at least the fuel cost in 100 yuan every month.

Third, self-inspection and maintenance skills

Although it is not recommended to replace the fuel filter by yourself, the owner can judge whether it is necessary to replace it by some simple methods. For example, if the vehicle is found to have weak acceleration, unstable idle speed or sudden increase in fuel consumption, it is likely to be a signal that there is a problem with the filter.

In addition, developing good car habits can also extend the life of filters. Try to refuel at regular gas stations to avoid using inferior fuel. Clean the oil tank regularly to prevent impurities from accumulating. Before long-distance driving, it is best to fill up the fuel tank to reduce the chance of air entering the fuel tank.

Some car owners shared a small coup: every time you refuel, first add a small bottle of fuel additive, which can effectively clean the fuel system and extend the service life of the filter. Although this will increase some costs, in the long run, it can save more maintenance costs.

The fuel filter may seem unremarkable, but it is important to protect the engine. Regular replacement can not only maintain vehicle performance, but also avoid unnecessary losses. As responsible car owners, we should pay attention to every detail and keep our car in the best condition.
