使用气缸压力表检测气缸压力,由于检测方法简便、实用,而且仪表轻巧、价格较低,故应用极为广泛。但使用气缸压力表检测气缸压力,也常出现测量结果误差较大,且根据测量结果一般无法直接确诊发动机具体故障部位的缺点。为更有效地使用气缸压力表,关键要尽可能克服或解决上述问题。 首先,尽量减少气缸压力表的测量误差。说明书中给出的某种型号发动机的气缸压力值,都是在特定的检测条件下得到的,因此在使用气缸压力表检测气缸压力时,必须满足相应的检测条件。实践表明,用气缸压力表检测出的气缸压力值,除与发动机本身的压缩比及气缸
The use of cylinder pressure gauge to detect cylinder pressure, as the detection method is simple and practical, and the instrument lightweight, lower prices, so the application is extremely wide. However, the use of cylinder pressure gauge to detect cylinder pressure, the measurement error is often large, and according to the measurement results generally can not directly diagnose the shortcomings of the engine specific fault location. In order to use the cylinder pressure gauge more effectively, it is crucial to overcome or solve the above problems as much as possible. First, try to minimize the measurement error of the cylinder pressure gauge. Instructions given in a certain type of engine cylinder pressure values are obtained under specific test conditions, so the use of cylinder pressure gauge to detect cylinder pressure, you must meet the appropriate testing conditions. Practice shows that the use of cylinder pressure gauge to detect the cylinder pressure, in addition to the compression ratio and the engine itself and the cylinder
