A Study on the Combustion Performance by the Improvement of In Cylinder Flow Motion in the Natural Gas Engine
실린더내 흡기유동개선이 천연가스엔진의 연소성능에 미치는 영향 연구
Abstract
In general, natural gas engine converted from gasoline engine has disadvantage of power decrease. In order to increase power output in natural gas engine, the improvement of in-cylinder flow motion has been believed as the most effective method. In this study, the geometry of combustion chamber in 4 valve DOHC natural gas engine is modified, and in-cylinder flow patterns is analyized. Also engine performance is evaluated according to the modification of in-cylinder flow motion.
