Abstract

엔진의 흡기장치는, 기계식과급기(5)와, 흡기밸브(14)를 개재해서 흡기통로(3)와 연통하고 배기밸브(42)를 개재해서 재기가스통로(41)와 연통하는 복수개의 엔지너 실린더(2)와, 그리고 흡기 및 배기밸브(14,42)사이의 밸브중첩기간(OL 1, OL 2)을 변화시키는 가변밸브타이밍기구(15)를 구비하고 있다. 가변밸브타이밍기구(15)는 소정의 고엔진회저수영역에서는 밸브 중첩기간(OL 2)을 넓히고, 소정의 저엔진회전수영역에서는 밸브중첩기간 (OL 1)을 좁힌다. 밸브중첩이 클 경우에는, 관성과급효과는, 엔진흡기행정시에 발새오딘 부압파가 엔진실린더(2)부터 그 상류 부분으로 돕립흡기통로(130내를 전파해서, 용적확대부(21,23)에서 반사한 후, 정압파가 되어 엔진실린더(2)로 복귀하도록 발생된다. 한편, 밸브중첩이 작을 경우에, 공명파급효과는, 같은 그루우프에 속하는 엔진실린더는 공명과급효과를 발생시키기 위해 그 흡입순으로 서로 인접하지 않도록 발생된다.
