Compression pressure of individual cylinder has big influence on engine performance parameters such as combustion pressure, indicated mean effective pressure (IMEP), emission, vibration, combustion noise and many other combustion parameters. Conventional method to check compression pressure uniformity is done by mechanical pressure gage and this method needs to disassemble related parts such as glow or ignition plugs which causes cost and time. Also this conventional method causes inaccuracy of cylinder pressure measurement because of different cranking speed results mainly from battery status and lubrication oil temperature. This study describes and suggests new methodology to measure compression pressure by analysis of CAM and crank sensor signal during cranking with high accuracy but without mechanical pressure gage or parts disassemble. Results, it is found that leak of cylinder has linear relationship with crankshaft angular speed during compression stroke so that cylinder leak can be detected by CAM and crank signal.
