Abstract: 본 발명은 배기가스의 일부를 흡기계통으로 재순환시켜 연료의 연소율을 높임으로써 NOx의 발생을 억제하는 배기가스 재순환 장치(EGR)에 관한 것으로, 특히, 흡기압이 배기압 보다 높은 경우 재순환 배기가스를 흡기계통으로 강제 압송할 수 있게 구성된 배기가스 재순환장치에 관한 것이다.
본 발명에 따른 배기가스 재순환장치는, 터보차저를 구비한 엔진에서 상기 터보차저 상류측 배기관에서 배기가스의 일부를 인출하여 냉각한 후 재순환관을 통해 흡기계통으로 재순환시키도록 구성된 배기가스 재순환장치에 있어서, 상기 터보차저에서 압축되어 엔진에 흡입되는 과급공기의 과급압과 엔진 연소실에서 배출되는 배기가스의 배기압을 비교하여 상기 과급압이 더 높은 경우 재순환관 내 배기가스를 흡기계통측으로 강제 압송하는 압송수단;을 포함하여 이루어지며, 이와 같은 구성에 따르면, 배기압이 흡기압 보다 낮은 저속,중속 구간에서도 엔진의 출력 저하 없이 배기가스의 재순환률을 높여 유해가스 발생량을 대폭 줄일 수 있고 고가(高價)의 재순환 밸브(EGR Valve)가 불필요하므로 제작원가가 낮다.-

Abstract: PURPOSE: An exhaust recirculating system is provided to forcibly send recirculation exhaust gas to a suction system in low and intermediate-speed sections in which suction pressure is higher than the exhaust pressure. CONSTITUTION: In an engine(1) having a turbocharger(3), an exhaust recirculating system withdraws some of exhaust gas from an exhaust pipe(2) of the upper side of the turbocharger and cools the exhaust gas and then recalculates the exhaust gas to a suction system through a recirculating pipe(10). The exhaust recirculating system includes a forcible sending unit comparing the supercharged pressure of supercharged air, compressed from the turbocharger and sucked in the engine, with the exhaust pressure of exhaust gas discharged from an engine combustion chamber, and forcibly sending the exhaust gas in the recirculating pipe to the suction system if the supercharged pressure is higher than the exhaust pressure.
