How to analyze the engine cylinder sealing test results of beiben V3 parts manufacturer. The following wide body car parts manufacturers will give you a detailed introduction.

There are seven factors affecting cylinder sealing, mainly including cylinder wear, piston ring damage, piston wear, valve seat damage, valve guide wear, cylinder gasket damage, valve clearance and so on.

What are the common diagnostic methods? It mainly includes the measurement of cylinder pressure, crankcase air blowby, cylinder air leakage and air leakage rate, vacuum degree of intake pipe, vibration measurement of abnormal noise caused by excessive wear of cylinder piston group, and the measurement of particle content of wear metal in crankcase.

For the measurement of cylinder compression pressure of beiben V3 accessories, it is mainly the pressure at the end of compression of the four stroke engine. Due to the pressure of the cylinder, the viscosity of the oil and the matching of the cylinder piston group, whether the adjustment of the valve mechanism is correct, the tightness of the cylinder gasket and other factors, when measuring the pressure of the engine cylinder, the sealing of the cylinder piston group can be diagnosed. If the sealing of the piston ring, valve and cylinder gasket is good, the valve clearance should be appropriate.

For beiben V3 accessories, the main methods for testing the engine sealing are to blow away the dirt around the spark plug with compressed air, and then remove the spark plug. For gasoline, the secondary high-voltage line of the ignition system should be pulled out for reliable grounding. In order to prevent electric shock and fire, the conical rubber plug of the cylinder pressure gauge should be inserted into the spark plug hole measured by the cylinder, and it should be righted and pressed, For the throttle valve, it shall be placed in the full open position, and the starter shall drive the corresponding crankshaft to rotate. If the needle indication of the pressure gauge is maintained, the rotation shall be stopped after the pressure reading. Then remove the pressure gauge and record the reading
