What is MacPherson Suspension?

Is it true that new items will be added to Subject 2? When will it be implemented?

Currently, no new items have been added to Subject 2, but there may be variations in different regions. The specific items still need to be implemented according to local regulations. Subject 2, also known as the small road test, is part of the motor vehicle driver's license assessment and refers to the field driving skills test. For small cars (C1/C2), the test items include five mandatory components: reversing into a garage, parallel parking, stopping and starting on a slope, turning at a right angle, and driving through curves (commonly known as S-turns). The items included in Subject 2 are: 1. Pile test: Correctly judging the spatial position of the vehicle body and maneuvering the vehicle at low speed to complete reversing or moving forward through spatial obstacles. 2. Reversing into a garage: Correctly judging the reversing trajectory of the vehicle and maneuvering the vehicle to complete reversing into a garage. 3. Stopping and starting on a slope: Accurately judging the stopping position; coordinating the use of the accelerator pedal, parking brake, and clutch to start smoothly. 4. Parallel parking: Maneuvering the vehicle to correctly park in a roadside parking space (garage) while in motion. 5. Driving through curves: Maneuvering the steering device while in motion to control the vehicle driving through curves. 6. Turning at a right angle: Correctly maneuvering the steering device while in motion to accurately judge the difference between the inner and outer wheels.

Where is the tire pressure display for the 2021 A6L?

Method to reset the tire pressure light for the 2020 Geely Vision X6: First, turn on the ignition switch, then press and hold the tire pressure monitoring reset button. After hearing a "beep" sound, release the button. The tire pressure monitoring system will store the current normal tire pressure data, automatically clear the previous data, and finally, the warning light on the dashboard will turn off, completing the tire pressure reset. Precautions for inflating tires: Always use a pressure gauge to check the tire pressure to avoid over-inflation, which could cause the tire to burst. After stopping the vehicle, wait for the tires to cool down before inflating, as driving increases tire temperature, which affects the pressure. Check the valve stem. If the valve stem and valve core do not fit smoothly or have any protrusions, depressions, or other defects, it may be difficult to inflate or measure the pressure. Ensure cleanliness when inflating. The air being pumped in should not contain moisture or oil, as this can deteriorate and damage the inner tube rubber. Do not exceed the standard pressure significantly and then deflate, nor should you over-inflate due to prolonged inability to inflate while traveling. Exceeding the standard pressure too much can cause excessive stretching of the cords, reducing their strength and affecting the tire's lifespan.

What does free charging for XPeng P7 mean?

XPeng Supercharger announced that in order to provide a more convenient and faster charging experience for car owners, it will offer lifetime free charging service for the first non-commercial owners of XPeng P7 vehicles who charge at designated charging stations. The specific conditions are as follows: 1. Only non-commercial use is eligible: The biggest difference between commercial and non-commercial vehicles is that commercial vehicles are intended to earn transportation fees, while non-commercial vehicles are not for profit. 2. First owner: The first owner refers to the first registered person of the vehicle. Only the first owner can use XPeng's free charging service. If you purchase a used XPeng from the second-hand car market, you will not be eligible for free charging. In other words, this policy "recognizes the person, not the car." 3. Free within 3,000 kWh per year: If the electricity used exceeds 3,000 kWh per year, the owner will need to pay for the extra. Taking the long-range version of XPeng P7 as an example, 3,000 kWh can charge the car approximately 37 times. This means the owner can drive about 26,000 kilometers for free each year, which is a fairly generous quota for most owners.

What type of engine oil is suitable for Volkswagen 1.4T?

Volkswagen 1.4T uses 0W40 engine oil. The 1.4T is a direct-injection turbocharged engine with a complex working environment inside the cylinders, requiring the oil to maintain good stability under high temperature and pressure. 0W40 oil exhibits strong fluidity under high temperatures and has high viscosity, allowing the oil film to effectively coat the cylinder surfaces for superior lubrication. Classification of engine oil: Automotive engine oils are divided into three types - mineral oil, semi-synthetic oil, and full synthetic oil. Mineral oil is only suitable for low-end vehicles or some new cars. Semi-synthetic oil is a blend of conventional oil and synthetic base oil, generally suitable for non-turbocharged mid-range models. Full synthetic oil has excellent high-temperature volatility resistance and deposition capability, making it suitable for high-temperature, high-speed, high-compression ratio engines like turbocharged engines. Functions of engine oil: Lubrication to reduce wear - There is rapid relative sliding between the engine's pistons and cylinders, as well as between the main shaft and bearing shells, which can easily cause wear. High-quality oil forms a sufficiently thick oil film between these sliding surfaces to separate them and reduce wear. Cooling - The oil carries heat back to the oil pan and dissipates it into the air, assisting the radiator in cooling the engine. Cleaning - Good engine oil can circulate carbon deposits, sludge, and worn metal particles from engine components back to the oil pan, flushing away contaminants generated on the parts' working surfaces through the flow of the lubricating oil.

What is the difference between Volkswagen CC 330 and 380?

The 2019 Volkswagen CC 330TSI is equipped with a low-power version of the 2.0T engine, while the 380TSI uses a high-power version of the 2.0T engine, with different engine power and torque. The numerical suffix on Volkswagen models indicates the maximum torque output of the vehicle's engine. A higher number signifies greater engine torque, which typically means a larger engine displacement, a higher vehicle grade, and a more expensive price. More details are as follows: 1. Different engine power: The 330 is a low-power version of the 2.0T engine, while the 380 is a high-power version of the 2.0T engine. Previously, the Volkswagen 330 used a 1.8T engine, and the 380 used a 2.0T engine. Later, the 330 was also upgraded to a 2.0T engine, but it remains the low-power version. The 330 has around 186 horsepower (Ps), while the 380 has around 220 horsepower (Ps), offering stronger performance. 2. Different torque: The numbers 330 and 380 on the rear of Volkswagen vehicles represent the engine torque data for the respective models. The 330 corresponds to a maximum torque of 320N·m, while the 380 corresponds to a maximum torque of 350N·m. These numbers are usually followed by letters, such as TSI, indicating that the vehicle is equipped with a turbocharged engine.

What Causes Abnormal Noises from the Car Steering Wheel?

The reasons for abnormal noises from the car steering wheel include damage to the clock spring in the steering wheel, which requires replacement of the clock spring; lack of lubrication in the steering column dust cover, necessitating the application of lubricant; insufficient lubrication in the shock absorber's plane bearing, also requiring lubrication; and loosening or damage of the stabilizer bar bushings, which may need shims or replacement. To quickly resolve steering wheel noise issues, it is essential to first identify the source of the noise. If the noise comes from inside the steering wheel, you can remove the steering wheel clock spring and apply some grease to see if the noise persists. If it does, replace the clock spring as it is already damaged. If the noise comes from below the steering wheel, it is likely due to the steering column dust cover. A lack of lubrication in the dust cover can cause friction noises. In this case, applying grease inside the dust cover will eliminate the noise. If the noise originates outside the car, it may be due to insufficient lubrication in the shock absorber's plane bearing. Applying grease to the plane bearing can help. If the noise continues after lubrication, replacement is necessary. Additionally, check if the stabilizer bar bushings are loose or damaged. Loose or damaged stabilizer bar bushings can cause noises not only when turning the steering wheel but also when driving on uneven roads. Loose bushings can be fixed by adding shims, while damaged ones must be replaced.
