커먼레일 중형 디젤엔진의 개념설계 및 초기 시험개발

An experimental feasibility study of the E3.9 engine with CP3.3 and EDC7C was conducted to understand the initial performance and the possibilityfor EURO-III regulation. ID cycle simulation far concept study was conducted using the BOOST. Also, some basic investigations through such various parameters as injection timing and rail pressure have been carried out to find the feasibility on EURO-III ESC mode. Based on the results, the feasibility of the E3.9 engine for EURO-III characteristics such as performance, emissions, and fuel economy was demonstrated.
