건설기계용 엔진의 국내 표준시험모드에 따른 배출가스 특성 및 개선

The emission standard of diesel engine on the construction equipment has been rapidly enhanced in advanced countries, because most of air pollutions was caused by construction equipment. So, all of the construction equipments will be tested for emission with standard measurement mode. But, the standard measurement mode of construction equipment is different for non-road and one for the road in korea. This study was conducted to measure emission characteristics of the construction equipment with changed standard measurement mode and to improvement the emissions experimentally.
