A Study on the Improvement of In-Cylinder Flow Motion in the Natural Gas Engine
천연가스엔진의 실린더내 흡기유동개선에 관한 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 are analyized. Also engine performance is evaluated according to the modification of in-cylinder flow motion.
