일반적으로, 경유를 원료로 사용하는 디젤 엔진(Diesel engine)은 열효율이 좋고 연료비용이 적게 드는 장점이 있어 트럭과 같이 큰 힘이 필요한 차량이나 장치 등에 주로 사용되고 있으며, 승용차에도 사용되고 있다.In general, diesel engines using diesel as a raw material have good thermal efficiency and low fuel cost, and are mainly used in vehicles or devices requiring large power, such as trucks, and also used in passenger cars.

그러나, 디젤 엔진은 열효율이 좋은 반면에 유해물질이 포함된 배기가스와 매연 등 입자상 오염물질을 다량 배출하기 때문에 대기오염의 주요 원인이 되고 있다.However, while diesel engines have good thermal efficiency, they generate large amounts of particulate pollutants such as exhaust gas and soot containing harmful substances, which is a major cause of air pollution.

상기 배기가스 중, 질소산화물(NOx)을 줄이는 방법으로 EGR(Exhaust Gas Recirculation) system을 이용하여 배기가스 중, 일부를 흡기매니폴드로 되돌려 배출되는 질소산화물(NOx)의 배기량을 감소시키고 있다.The exhaust gas is used to reduce the amount of nitrogen oxides (NOx) discharged by returning part of the exhaust gas to the intake manifold by using an exhaust gas recirculation (EGR) system as a method of reducing nitrogen oxides (NOx).
