The timing belt and spark plug were changed two days ago, and now the first gear is changed to the second gear, and it will take some time for the speed to come up. What is the maximum speed for running the high-speed throttle? If the car is unstable at idle speed, it is easy to stall, unstable when refueling, weak acceleration, and the engine is easy to shake. If the car is within 80,000 kilometers, the timing belt should be replaced.

The timing belt is usually replaced once every two years or about 6W kilometers.

Because the timing belt is a preventive replacement, it should be replaced before the service life specified by the manufacturer, because once the belt breaks, it will directly affect the driving safety.

Precautions for replacing timing belt

Timing belt is an important part of the whole automobile engine. The main function of timing belt is to ensure the normal operation of intake and exhaust by connecting with crankshaft and matching with a certain transmission ratio. The engine of an automobile does work mainly in intake, compression, work and exhaust.

These four main tasks can drive the car to run. Although it looks simple, in fact, the working process of the engine is extremely complicated. The timing of each step should be coordinated with the motion state and position of the piston and valve, so that the intake and exhaust and piston lifting can be coordinated with each other.

Therefore, the timing belt plays a very important role as an intermediate bridge in the whole running process of the engine. Driven by the crankshaft, the kinetic energy is transferred to the corresponding parts, so that the piston, valve and other parts can be kept in the correct position in different steps, which can make the engine run normally. ?

At present, synchronous belts are all rubber products, so they have a certain life and service life. According to the regulations of various automobile brands, it needs to be replaced in time when it reaches a certain service life or mileage. If it is not replaced according to the regulations, the timing belt is likely to burst and break, which will easily lead to engine jacking and cause great damage to the engine.
