Why does the automatic transmission make noise when slowly releasing the brake?

Automatic transmission making noise when slowly releasing the brake may be due to the friction between the brake pads and the brake disc, which is normal. The car's braking system consists of a vacuum booster pump, master brake cylinder, brake caliper, brake pads, and brake disc. After opening the engine hood, you can see a metal disc below the windshield on the driver's side, which is the vacuum booster pump. The brake caliper is what we commonly refer to as the brake caliper. In front of the vacuum booster pump is the master brake cylinder, which has an oil reservoir on top for holding brake fluid. Brake fluid is a liquid that easily absorbs water. If the brake fluid has too much water content, it can lead to reduced braking force.

Why does an automatic transmission car keep stalling when starting?

Theoretically, automatic transmission vehicles should not experience stalling. If stalling occurs, it is necessary to first determine whether it is a fault-induced stall or a resistance-induced stall. A resistance-induced stall happens when the car's current power is less than the external resistance it faces, making it insufficient to move the car forward, thus causing the engine to stall. A fault-induced stall can be caused by issues in the fuel system, intake system, or ignition system—any problem in one of these three systems can lead to stalling. Common causes of fault-induced stalling include: 1. Problems with the ignition coil; 2. Issues with the spark plugs, such as reaching the end of their lifespan; 3. Problems with the throttle position sensor; 4. Use of low-quality gasoline, leading to clogged fuel injectors. The specific cause of stalling needs to be diagnosed at a 4S shop or a professional repair shop.

Is a 1.0T engine displacement sufficient for small cars?

A 1.0T engine is sufficient for small cars. The power output of a 1.0T engine is roughly equivalent to that of a 1.6L naturally aspirated engine. However, due to turbocharging, the torque is slightly higher than that of a 1.6L naturally aspirated engine. There is no need to worry about the power; it is absolutely sufficient. Function of Turbocharging: The main function of turbocharging is to increase the engine's air intake, thereby enhancing the engine's power and torque, making the car more powerful. Effect of Turbocharger: When a turbocharger is installed on an engine, its maximum power can increase by 40% or more compared to when it is not equipped with a turbocharger. This means that the same engine can output greater power after being turbocharged.

Is Hill Start Assist Necessary for Automatic Transmission Vehicles?

Hill start assist is necessary for automatic transmission vehicles. This function, derived from the ESP system, serves the following purpose: when starting on a slope, even after the driver's right foot leaves the brake pedal, the vehicle can maintain braking for a few seconds to prevent rolling back and potential accidents. Typically, hill start assist is enabled by default; it activates as soon as the vehicle is started, without requiring manual activation by the driver. To use hill start assist properly, the following conditions must be met: 1. The gear shift lever must be in any position other than P (Park); 2. The accelerator pedal must not be pressed; 3. The vehicle must be stationary; 4. The parking brake must not be engaged. When these basic conditions are satisfied, the system activates hill start assist control when the driver further presses the brake pedal while the vehicle is stopped.

What is the correct parking procedure for an automatic transmission car?

The correct parking procedure for an automatic transmission car is: 1. First, press the brake pedal and wait for the car to come to a complete stop; 2. Shift the gear from D (Drive) to N (Neutral), then engage the handbrake; 3. Finally, turn off the engine, and after the engine is off, shift the gear to P (Park). Modern car technology is highly advanced, and automatic transmission cars can generally be turned off in either N or P gear without causing damage to the engine. Although P gear is the parking gear, it should not be used as a substitute for the handbrake. When parking on a slope, while shifting to P gear can keep the car stationary, it is advisable to also use the handbrake to prevent the car from rolling, especially on steeper inclines.

How often should a car's tires be inflated?

There is no specific time frame, but it's best to check the tire pressure periodically, generally around every two weeks. Inflate if the pressure is insufficient. Normal tire pressure: The normal range for car tire pressure is between 230-250kpa. However, the exact normal tire pressure should be based on the manufacturer's recommended value. Hazards of low tire pressure: It can cause excessive wear on certain parts of the tire, shortening its lifespan. It also makes the tire sidewall prone to bending and breaking, leading to blowouts. Hazards of high tire pressure: It reduces the contact area between the tire and the ground, weakening traction and increasing braking distance, which affects driving safety.
