Nov 11 , 2021
1. Start the engine and run to the normal operating temperature, turn off the engine and remove all spark plugs after the engine stops running.
2. Fully open the valve, and use the connecting head of the pressure gauge pressed tightly on the spark plug hole.
3. With a motor to drive the engine to 100-150r/min rotation speed of 3-5 seconds,then the pointer on the meter will rise gradually,It stops at a certain point,and the indicator value is the compression pressure of the cylinder.
4. Press the button to reset the pointer to zero, and repeat the measurement 23 times according to the above steps to improve the measurement accuracy.
5.General auto cylinder pressure > 0.9mpa, and △< 8% (each cylinder pressure difference, gasoline engine does not exceed the average pressure of each cylinder 8%).
