Usage:

1. Start the engine and run to the normal working temperature. After the engine stops running, unload all spark plugs;

2. Make the throttle fully opened and press the connection of the pressure gauge on the spark cold hole;

3. Motors drive the engine to rotate at 100-150R/MIN speeds for 3-5 seconds. At this point, the pointer on the instrument will gradually rise, but will stop at a certain value. At this time, the indicator value is the compression pressure of the cylinder;

4. Press the button to zero the pointer;

5. According to the above steps, the measurement is repeated 2 to 3 times to improve the measurement accuracy;

6. Generally, the cylinder pressure of car is more than 0.9 MPA, and 4 < 8% (the pressure difference of each cylinder, gasoline engine does not exceed 8% of the average pressure of each cylinder). If the measured value is less than the prescribed value, and the intake system is normal, it can be explained that there is leakage between the cylinder and piston, cylinder head. It may be that the original cylinder, piston, valve, piston ring appear abrasion, ablation and other bad conditions. If the measured value is greater than the prescribed value and the intake and exhaust system is normal, the possible reason is the serious volume of combustion chamber.
