How to judge the tightness of generator belt?

The tightness of the generator belt can be reduced by 0.5 1cm: 1 by finger pressing. The timing belt is an important part of the engine gas distribution system. By connecting with the crankshaft and matching with a certain transmission ratio, the accuracy of the intake and exhaust time can be ensured.

2. The belt is used to replace the gear transmission because the belt has low noise, accurate transmission, small self-change and easy compensation. Obviously, the life of the belt is definitely shorter than that of the metal gear, so the belt should be replaced regularly;

3. When the engine is running, the function of timing belt is piston stroke (up and down movement), valve opening and closing (time) and ignition sequence (time). Under the connection of time series, it is necessary to keep "synchronous" operation at all times;

4. Timing, that is, through the timing mechanism of the engine, allows each cylinder to do it accurately: when the piston is at the top dead center, the valve just closes and the spark plug just ignites.
