What is the use method of the cylinder pressure detector

First, install the cylinder pressure gauge on the engine, then preheat the car, remove the spark plug or fuel injector, then fully open the throttle valve, screw the threaded pipe joint on the spark plug, and read the indicator displayed on the pointer after the starter is turned on. pressure value.

　　

The emergence of the cylinder pressure detector is to measure the cylinder pressure easily and easily. It is mainly composed of a pressure sensor type cylinder pressure detector, a starting current type cylinder pressure detector, an inductive discharge type cylinder pressure detector, etc. It is used to evaluate the cylinder pressure of each cylinder. Equalization of cylinder pressure. You can use compressed air to blow off the foreign matter around the spark plug first, and then remove the spark plug. You should also unplug the secondary high-voltage wire of the ignition system and secure the tower iron to avoid electric shock or fire. Insert the tapered rubber head of the special cylinder pressure gauge into the Enter the spark plug hole, open the throttle, drive the pressure pointer to rotate, take off the pressure gauge, and record the value.
