Chapter Four Measurement of Cylinder Pressure

I. Detection of Cylinder Pressure

Measurement of cylinder pressure is the major index for judgment of engine working condition,

through which, we can definitely judge if a certain system of engine works well. Therefore, during

maintenance of engine, measurement of cylinder pressure is indispensable.

1. Measuring process

1.1 Turn off ignition switch, pull out all ignition cables

from spark plug side, and then pull out harness

connector of injection nozzle.

1.2 Use a spark plug sleeve to loosen the spark plug

whose cylinder will be measured. Explanation: do not

remove the spark plug whose cylinder will not be

measured.

Please select a cylinder pressure

gauge with accurate reading and let its

pointer return to zero; otherwise, it may affect

accuracy of reading.
