ガスエンジン用副室点火式大型急速圧縮膨張装置の開発

抄録

The prechamber combustion characteristics were studied using a rapid compression and expansion machine (RCEM) to improve the efficiency of cogeneration natural gas engines. The torch flames generated by a prechamber were used to investigate the effect that a prechamber has on the main combustion. In our previous study, we observed the correlation between the torch flame and the main flame (which is a so-called “prechamber combustion”) as well as the knocking phenomena for various prechamber configurations. In this study, in order to investigate the effects of engine size on prechamber combustion characteristics, large size RCEM were developed.
