What is the Auto Start-Stop Function in Cars?

Auto Start-Stop is a system that automatically shuts off the engine when the vehicle comes to a temporary stop during driving and restarts it when it's time to move forward again. The working principle of the Start-Stop system: When the vehicle stops due to traffic congestion or at an intersection, and the driver presses the brake pedal and shifts to neutral, the Start-Stop system automatically checks: the engine is idling and not in gear; the wheel speed sensors of the anti-lock system show zero; the electronic battery sensor indicates there's enough energy for the next start. Once these three conditions are met, the engine automatically stops.

What is the principle of a car transmission?

The principle of a car transmission is to utilize gear combinations with different numbers of teeth in meshing transmission to achieve changes in speed and torque. The functions of a transmission are: 1. To alter the transmission ratio, meeting the traction needs under various driving conditions and enabling the engine to operate under favorable circumstances; 2. To allow the car to move in reverse; 3. To interrupt power transmission, such as when the engine is started and idling, when the car is shifting gears or parked, cutting off power to the drive wheels; 4. To achieve neutral gear, stopping the transmission's power output when the clutch is engaged. The functions of a manual transmission are: 1. To change the transmission ratio, expanding the range of torque and speed variations for the drive wheels; 2. Under the premise that the engine's rotation direction remains unchanged, to use the reverse gear to enable the car to move backward.

How to Determine Whether Brake Pads Should Be Replaced?

To determine whether brake pads should be replaced, you can check the remaining thickness of the brake pads. Brake pads, also known as brake linings, are friction materials fixed on the brake drums or discs that rotate with the wheels. Once the friction material is worn out, the brake pads should be replaced promptly. Otherwise, the metal backing plate will come into direct contact with the brake disc, resulting in loss of braking effectiveness and damage to the brake disc. Steps to replace brake pads: 1. Release the handbrake, loosen the wheel hub screws of the wheel where the brake pads need to be replaced, and use a jack to lift the car and remove the tire; 2. Remove the tire to expose the brake caliper and brake disc, and apply lubricating oil to the screws or nuts that need to be loosened or removed; 3. Hang the brake caliper with a rope and remove the old brake pads; 4. Open the hood and unscrew the cap of the brake fluid reservoir; 5. Install the new brake pads in the correct position.
