What is generally used to detect cylinder pressure?

[ZacharyFitz]

It can be detected using a cylinder pressure gauge. The method for measuring cylinder pressure with a cylinder pressure gauge is as follows: 1. Run the engine until it reaches normal operating temperature, with coolant temperature between 85-95°C. 2. Remove all spark plugs or fuel injectors, and ground the high-voltage wires. 3. Fully depress the accelerator pedal to open the throttle completely. 4. Press the conical rubber adapter of the cylinder pressure gauge tightly into the spark plug hole of the cylinder being tested, or screw the threaded adapter into the spark plug hole. 5. Crank the starter for 2-3 seconds until the gauge needle stabilizes, then read the measurement. Press the one-way valve to reset the gauge needle. Each cylinder should be measured at least twice.
