플라즈마 EGR 조합시스템 디젤기관의 성능 및 배기 배출물 특성 = Characteristics of Performance and Exhaust Emissions in Diesel Engines with a Combined Plasma EGR System

다국어 초록 (Multilingual Abstract)

The effects of non-thermal plasma reactor and recirculated exhaust gas on performance and exhaust emissions under four kinds of engine loads were experimentally investigated by using a four-cycle, four-cylinder, swirl chamber type, water-cooled diesel engine with a combined plasma EGR system operating at three kinds of engine speeds. The purpose of this study is to develop the combined exhaust gas recirculation(EGR) control system with a non-thermal plasma reacto for reducing NOⅹ and soot emissions simultaneously in diesel engines. The EGR system is used to reduce NOⅹ emissions, and the non-thermal plasma reactor is used to reduce soot emissions. The plasma system in this study is a flat-to-flat type reactor operated by a plasma power supply. The experiments arc performed at the fixed fuel injection timing of 4˚ ATDC regardless of experimenlal conditions. It is found that NOⅹ and soot emissions are decreased, especially soot emissions are markedly reduced at the middle loads, as the applied electrical voltage of plasma reactor is elevated.<br/>
