Analysis on the test method of engine cylinder pressure

The engine cylinder pressure is an important index of evaluating the performance of engine power. The test is required frequently on the process of checking, assessment and maintenance. This article elaborates the engine cylinder pressure measuring instrument, the test method and the skill from the aspect of automobile practice technology. It also finds out the possible reason why the engine breaks down from systematically analysis on the test data in theory. Furthermore, it provides scientific and reasonable basis for the motor engine technical service.
