A Study for Reduction of Combustion Noise in Diesel Engine by Wiebe's Combustion Function
Wiebe 燃燒函數에 의한 디이젤機關 의 燃燒騷音低減 에 관한 硏究
Abstract
This research is to find a means of reducing diesel engine combustion noise with none or minimum sacrifice of engine performance by investigating the influence of Cylinder Pressure Level(CPL). For this purpose, modified Wiebe's combustion function, considering the heat release curve as a combustion of both premixed and diffusive combustion portion, was exclusively used to obtain the indicator diagram and computer coeds were developed for the numerical analysis. Following are the results of this research. (1) CPL increases almostly with lag of ignition timing increasing .alpha. and decreasing. theta.
본 논문에서는 디이젤기관의 연소소음의 저감을 최종목표로 하여 Wiebe의 연 소함수에 의해 근사시킨 열발생속도의 변화가 디이젤기관의 연소소음 및 도시열효율에 미치는 영향에 관하여 수치실험을 통하여 해석검토하였다.
