엔진(1)은, 공기압을 받아 시동하는 주기관(10)과, 주기관(10)으로 공기를 도입하는 흡기통로(20)와, 흡기통로(20)를 흐르는 공기를 과급하는 배기터빈 과급기(40)와, 주기관(10)을 시동하기 위한 공기가 가압 충전된 공기원(61)과, 공기원(61)으로부터 주기관(10)으로 이르는 공기 유로(63)와, 배기터빈 과급기(40)에 의한 과급에 가세하는 가세 장치(70)를 구비한다. 가세 장치(70)는, 공기 유로(63)에서의 중간 부위에서 분기되어 배기터빈 과급기(40)로 이르는 가세용 유로(71)를 구비한다. An engine (1) is provided with: a main engine (10) which starts in response to an air pressure; an intake passageway (20) for guiding air to the main engine (10); an exhaust turbine supercharger (40) which supercharges the air flowing through the intake passageway (20); an air source (61) in which air for starting the main engine (10) is pressurized and filled; an air passageway (63) leading from the air source (61) to the main engine (10); and an assistance device (70) which assists the supercharging by the exhaust turbine supercharger (40). The assistance device (70) includes an assisting passageway (71) which branches away from a midway portion of the air passageway (63) and leads to the exhaust turbine supercharger (40).
