What is the usage method of a cylinder pressure gauge
1 Answers
The usage method of a cylinder pressure gauge is: 1. Start the engine, let it warm up, then turn it off, remove the spark plug, and use some accessories to connect the cylinder pressure gauge to the spark plug threaded hole on the cylinder head; 2. Turn the throttle to the fully open position, press the start button until the cylinder pressure gauge stops rising; 3. Read the maximum compression pressure in the cylinder from the gauge. Repeat the measurement 2 to 3 times, and take the average value as the compression pressure in the cylinder. The cylinder pressure gauge consists of two parts: the indicating mechanism and the measuring components. When measuring large diesel vehicles, the compressed gas in the cylinder enters the spring tube in the indicating mechanism through the connecting head, connecting pipe, secondary joint, hose component, valve body joint, and main body joint, causing displacement at its end. Through the connecting rod and sector gear, it is transmitted to the central gear, causing the pointer to rotate and indicate the air pressure value on the dial.
