该论文已在赫尔辛基举行的第28届CIMAC大会上发表，论文的版权归CIMAC所有。The pre ignition caused by lubricating oil has been becoming apparent with the increasing mean effective pressure more than approximately 1.8 MPa including the passenger car engines and one of the critical issues nowadays for the most premixed combustion engines because it could damage the engine with the remarkably high maximum firing pressure. This phenomenon could be the impediment to the improvement of the engine efficiency and the increase of mean effective pressure in the future development of engines because it becomes severer by increasing compression ratio and mean effective pressure. In consideration of the fact that this phenomenon is much more apparent on the industrial gas engines in Japanese market where the city gas with very low Methane Number is used, it is expected that this issue will be more common when LNG with the wide range of Methane Number will be used as the fuel of gas engines all over the world from now, especially in the marine application where Methane Number changes also depending on the tank level.
