This paper first proposes that cylinder tightness is an important factor affecting engine performance, which can directly reflect engine technical conditions. Cylinder tightness directly affects cylinder compression pressure, and cylinder compression pressure directly affects engine drag torque. Then, based on the test of real engine, the formula of the relation between the drag torque and the compression pressure is obtained by using the method of linear regression analysis, which provides a real and effective new method and means for inspecting the cylinder sealing. Data is obtained by preliminary analysis was carried out on the data of the basic characteristics, contact, and then use regression model to establish correlation between variables, with the method of mathematical model to describe the relation between resistance torque and compression pressure, through the relationship to provide scientific and effective in sealing cylinder detection method, make forecasting data more real and effective, More guidance for cylinder maintenance and state detection.
