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 two-layer ultra-lean rapid 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 feasibility of the concept was investigated using a single-cylinder engine, and the engine data was verified by means of numerical simulation and fundamental combustion experiments using a constant volume chamber.
