0-D 코드를 이용한 가솔린 점화기관의 성능 민감도 해석

With the increasing worldwide concern on low quantity of energy resource and environmental problems, the technological innovation on IC engine for automotive use in terms of engine performance and efficiency is highly required among car makers. To meet these requirements, many engine-related geometric factors which influence on engine performance should be fully understood, In this research, the sensitivity analysis was carried out to assess the effects of many engine sub-parameters on engine performance. To this end, the conventional 4-stroke, 4-cylinder gasoline SI engine was modeled and its performance was simulated with varying engine sub-parameters, For the performance analysis of IC gasoline engine, AVL BOOST, the commercial engine cycle simulation code, is adopted. The effects of exhaust manifold runner length, exhaust port length, intake manifold runner diameter on engine performance are mainly presented.
