Abstract

본 발명은 고속회전시의 출력향상을 위해 배기맥동을 이용하는 2사이클 엔진에 관한 것으로서, 저회전, 저스로틀 밸브의 개도시에 생기기 쉬운 배기중에 대한 탄화수소 배출량 증가를 커다란 출력 저하를 초래하지 않고 감소시킬 수 있는 배기장치를 제공하는 것이다.
또한, 2사이클 엔진(16)의 배기관(22)중에 확경된 밸브실(41)을 형성하고, 스로틀밸브(39)와 연동하여 스로틀 밸브의 개도가 낮을 때 배기통과 면적을 좁히는 교축밸브(24)를 밸브실(41) 내에 배설하고, 교축밸브(24)를 실린더면(21)으로 부터 상기 교축밸브까지의 배기관내 용적의 엔진 배기량에 대한 비율(Kv)이 1Kv 5가 되는 관계를 만족하는 위치에 배설하고, 또 밸브실(41)의 단면적을 상기 단면적의 배기관(22) 단면적에 대한 비율(Ka)이 1.1Ka
