Timing belt is a component of automobile engine valve system. Accurate control of intake and exhaust time of automobile engine is inseparable from the good cooperation between timing belt and crankshaft. But the timing belt is not made of steel after all, and the belt will be damaged. So it also needs to be replaced regularly. Generally, it needs to be replaced once every 80,000 kilometers, and then every 60,000 kilometers.
If there is something wrong with the timing belt, it will directly affect the intake and exhaust of the engine and the work of the engine. If the car engine suddenly shuts down and restarts, the speed is very high and the noise is very high. It is very likely that the timing belt is broken.
Extended data:
Automobile engine timing belt has the following functions:
Timing belt plays a connecting role. The upper part is connected with the timing wheel of the engine cylinder head, and the lower part is connected with the crankshaft timing wheel. The timing wheel is connected to the camshaft, and there is a cam on the camshaft. The contact point of the timing belt is a small rocker arm, which generates pressure through the power brought by the timing belt and plays a top role.
The function of jacking up the intake valve is to let atomized gasoline enter the cylinder, and when jacking up the exhaust valve, it is to let exhaust gas out of the cylinder; When the concave part of the camshaft touches the small rocker arm at the same time, the intake valve and the exhaust valve are closed at this time.
Phoenix. Com- the better. Installing a timing belt is much more difficult than installing a rubber belt.
