What is the correct method for shutting down an automatic transmission car?

The correct steps for shutting down an automatic transmission car are as follows: 1. First, slow down the car and press the brake, then shift into N (Neutral) gear. 2. Engage the handbrake firmly and release the foot brake. Once the car comes to a complete stop, shift into P (Park) gear. 3. Finally, turn off the ignition and remove the key to complete the shutdown process. Below is some information about automatic transmissions: (1) Automatic transmission cars typically use hydraulic transmission devices to replace the mechanical clutch found in manual transmission cars, hence there is no clutch pedal. (2) When the engine speed of an automatic transmission car is low, the torque transmitted by the fluid is limited and insufficient to propel the car forward. (3) When the gear selector of an automatic transmission car is placed in the drive (D) position and the brake pedal is released, increasing the throttle and engine speed raises the transmitted torque, enabling the car to move forward.

What Causes a Thud Sound When Driving Over Uneven Roads?

If your car makes abnormal noises when driving over uneven roads, it may indicate a faulty shock absorber. The solution is to replace it with a new one. Alternatively, the issue could stem from a damaged shock absorber top mount rubber, which requires replacing the aged buffer rubber with a new one. More details are as follows: 1. The connection points between the car's shock absorbers and the body are equipped with buffer rubbers, which are rubber components. Over time, these rubber parts can harden and age, leading to abnormal noises when traversing bumpy roads. 2. Shock absorbers are considered wear-and-tear parts in vehicles, though they typically last a long time. Eventually, they may develop oil leaks, necessitating replacement. 3. When purchasing shock absorbers, opt for original equipment manufacturer (OEM) parts rather than those from smaller manufacturers, as OEM parts offer more stable and reliable quality. 4. To protect your vehicle, reduce speed when driving over bumpy roads or speed bumps. Additionally, ensure both wheels cross speed bumps almost simultaneously to minimize impact on the shock absorbers and suspension.

Is it necessary to use 95-octane gasoline for new cars?

Whether a new car requires 95-octane gasoline depends on the specific brand and model. Generally, most naturally aspirated engine models can use 92-octane gasoline. It is advisable to follow the fuel requirements specified in the vehicle's manual. More details are as follows: 1. In terms of basic composition, gasoline has two important components: n-heptane and isooctane. The octane rating represents the proportion of isooctane. For example, 92-octane gasoline contains 92% isooctane and 8% n-heptane. 2. Different octane ratings primarily prevent engine "knocking." Generally, vehicles designed for 95-octane gasoline should never use 92-octane, as it can easily cause cylinder knocking. 3. Using 95-octane gasoline in a vehicle designed for 92-octane is less severe and at least won't cause "knocking." There is no scientific basis for the claim that higher-octane gasoline saves more fuel during highway driving. To save fuel, focus more on route planning and driving habits, such as avoiding sudden braking to reduce kinetic energy loss.

What is the PCV valve in Wuling's recall?

Wuling's PCV valve is part of the engine's crankcase forced ventilation system. Detailed information: Introduction: PCV stands for Positive Crankcase Ventilation control system in Chinese. The PCV valve consists of a valve body, valve, and valve cover, and is typically installed between the valve rocker cover and the intake manifold. PCV valve inspection method: After reinstalling the PCV valve, remove the crankcase intake pipe from the air filter, lightly cover the pipe opening with a thin piece of paper. As the pressure in the crankcase decreases, the paper should be noticeably sucked towards the pipe opening. Additionally, after stopping the engine, remove the PCV valve and shake it by hand to check. If a 'click' sound is heard, it indicates that the PCV valve is flexible and usable.

How to Maintain a Vehicle That Will Not Be Used for a Long Time?

Maintenance methods for vehicles that will not be used for a long time: 1. Loosen the ground wire of the battery and reconnect it when in use to ensure no power loss. Additionally, change the engine oil and oil filter every 5,000 kilometers. If the vehicle is left unused for half a year, these should also be replaced. Brake fluid and gear oil should be completely replaced every three years. 2. If possible, it is best to store the car in a garage. If parked in an open area, at least cover the car with a car cover. When choosing a car cover, opt for a thick, multi-layered one to effectively reduce the impact of sunlight on the paint. Ensure the car cover fits properly to avoid unnecessary friction on the paint caused by wind. 3. Tighten all connections on the vehicle. Due to vibrations, bumps, and swaying during driving, connections may become loose or worn. Therefore, regular tightening during maintenance is essential. The daily tightening of connections directly relates to driving safety, especially for critical components like steering, braking, and transmission systems—never overlook this.
