Abstract

This paper presents characteristics of diesel combustion and emissions according to adoption of various combustion chamber geometry. In order to suggest suitable combustion chamber geometry of the common rail diesel engine for electric generative use, 5 type of geometry chamber was found performance for combustion chamber to respond fuel efficiency. Combustion chamber geometry affects combustion characteristics due to change target area of spray in the combustion chamber and the main factor was the bowl aspect ratio of combustion chamber. Using the results of simulation, the effects of the variable combustion chamber can be improved the fuel efficiency for electric generation.

본 연구는 연소실 형상 변화에 따른 디젤연소와 배출가스의 특성에 대해 살펴보았다. 발전용 커먼레일 디젤엔진의 최적화 설계를 위한 연소실형상을 제시하기 위해 5가지 타입형상을 연비 측면에서 계산하였다. 연소실 형상은 연소 시 분무면적을 변화시킴으로서 연소특성에 영향을 주었으며 이러한 주요요소는 연소실 형상 비였다. 이러한 수치해석의 결과는 연소실 형상의 변화는 발전기의 연비 개선을 가능하도록 한다고 판단되었다.
