The charging current of a car battery should be adjusted to 1.5 to 2.5A. The functions of the battery are: 1. To supply power to the starting system, ignition system, and electronic fuel injection system when starting the engine; 2. To power the car's electrical equipment when the engine is off or at low idle; 3. To participate in power supply when the power demand exceeds the generator's supply capacity; 4. To stabilize voltage and protect the electronic equipment in the car. The maintenance methods for a car battery are: 1. Clean the battery regularly; 2. Reduce the use of electrical equipment when the engine is off; 3. Replace the battery regularly; 4. Start the car periodically.

What to Do If the Brake Pump Leaks Oil?

The solutions for a leaking brake pump are: 1. Replace the brake pump oil pipe; 2. Clean impurities or replace the sealing ring; 3. Reinstall the brake pump screws. The brake pump is an indispensable chassis braking component of the braking system. Its main function is to push the brake pads, which then rub against the brake drum to slow down or stop the vehicle. When the brake pedal is pressed, the master cylinder generates thrust to pressurize the hydraulic oil to the wheel cylinders. The pistons inside the wheel cylinders move under hydraulic pressure, pushing the brake pads. The reasons for brake pump damage are: 1. Dirty brake oil causing wear on the wheel cylinders; 2. Aging and wear of the brake wheel cylinder rubber cups; 3. Poor sealing.

How to Use the Electronic Parking Brake in an Automatic Transmission Vehicle?

The method for using the electronic parking brake in an automatic transmission vehicle is as follows: 1. With the vehicle stationary and the brake pedal depressed, pull the electronic parking brake button upward to activate the electronic parking brake; 2. With the vehicle stationary and the brake pedal depressed, press the electronic parking brake button downward to release the electronic parking brake. The electronic parking brake, also known as the electronic parking brake system, integrates the temporary braking function during driving with the long-term braking function after parking, and achieves parking braking through electronic control. The electronic parking brake is a technology that realizes parking braking through electronic control. Its working principle is the same as that of the mechanical handbrake, both achieving control of parking braking through the friction generated between the brake disc and the brake pads, with the control method changing from a mechanical handbrake lever to an electronic button.

How many kilometers should the original spark plugs be replaced?

Original spark plugs generally need to be replaced after driving 40,000 to 60,000 kilometers under normal maintenance conditions. However, this may vary depending on the brand and engine type, so it is recommended to follow the user manual. You can refer to the following maintenance standards for replacement: platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers. Spark plugs are a crucial component of a gasoline engine's ignition system. They introduce high-voltage electricity into the combustion chamber and create a spark by jumping the electrode gap, thereby igniting the combustible air-fuel mixture in the cylinder. Spark plugs mainly consist of a terminal nut, insulator, terminal stud, center electrode, side electrode, and shell. The main types include: standard spark plugs, projected insulator spark plugs, electrode-type spark plugs, seat-type spark plugs, pole-type spark plugs, and surface-gap spark plugs.
