Abstract

Research on natural gas lean-burn engines is being performed to reduce the environmental impact of the internal combustion engine. This study proposed a ultra-lean rapid two-layer distribution combustion concept that uses an engine with a sub-chamber equipped with a direct-injection injector to achieve both thermal efficiency enhancement and NOx reduction. The effects of the sub-chamber specifications on combustion were investigated by single-cylinder engine tests and constant volume chamber combustion tests. Consequently, we confirmed the effects of the sub-chamber specifications on engine performance and grasped the behavior of burned gas jet from sub-chamber.
