In the working process of the automobile engine, air intake, compression, explosion and exhaust continuously occur in the cylinder.

Four processes, and the timing of each step should match the motion state and position of the piston Close, so that the intake and exhaust and piston lift coordinate with each other, timing belt in the engine
Acting as a "bridge", the force is transferred to the corresponding parts under the drive of the crankshaft.

Many high-end cars use metal chains to replace belts in order to ensure the stability of the timing system. Because the vehicle timing tooth belt will cause damage to the internal valve of the engine after breaking, the harm is greater, so the general manufacturers have a replacement cycle for the timing belt.

The timing belt is a rubber part, and with the increase of engine working time, the timing belt and the right

The accessories of the timing belt, such as the timing belt tensioner, timing belt tensioner and water pump, will be issued Cause wear or aging. Therefore, all engines equipped with timing belts, manufacturers will have strict

The timing belt and accessories are required to be replaced regularly within the specified period, and the replacement cycle is followed by hair

The structure of the motivation varies, generally when the vehicle travels to 60,000 to 100,000 kilometers Should be replaced, the specific replacement cycle should be based on the vehicle maintenance manual instructions.

The timing belt is generally considered to be replaced at 80,000 km. Even if you have a timing belt in your car, you can't replace it if it breaks. Therefore, when the total driving distance reaches 80,000, it is recommended to consider replacing it.
