플라즈마 EGR 조합시스템 터보 인터쿨러 ECU 컴먼레일 디젤기관의 매연, CO 및 CO₂배출물 특성 = Characteristics of Soot, CO and CO₂Emissions in Turbo Intercooler ECU Common-Rail Diesel Engines with a Combined Plasma EGR System

다국어 초록 (Multilingual Abstract)

The aim in this study is to develop the combined turbo intercooler EGR system with a non-thermal plasma reactor for reducing exhaust emissions and improving fuel economy in ECU common-rail diesel engines. In this study, the characteristics of soot, CO and CO₂emissions under four kinds of engine loads are experimentally investigated by using a four-cycle, fourcylinder, direct injection type, water-cooled ECU common-rail diesel engine with a combined turbo intercooler plasma exhaust gas recirculation(EGR) system operating at three kinds of engine speeds. The EGR and non-thermal plasma reactor system are used to reduce NOx emissions, and the non-thermal plasma reactor and turbo intercooler system are used to reduce soot and THC emissions. The plasma system is a flat-to-flat type reactor operated by a plasma power supply. The fuel is sprayed by pilot and main injections at the variable injection timing between BTDC 15˚ and ATDC 1˚ according to experimental conditions. It is found that soot emissions with increasing EGR rate are increased, but are decreased as the applied electrical voltage of the nonthermal plasma reactor is elevated at the same engine speed and load. Results also show that CO and CO₂emissions are increased as EGR rate is elevated, and CO emissions are increased, but CO₂emissions are decreased as the applied electrical voltage of the non-thermal plasma reactor is elevated at the same engine speed and load.
