본 발명은 실린더, 상기 실린더에서 왕복이동하는 피스톤, 상기 실린더에 결합되고 상기 실린더의 배기가스를 배출하는 배기밸브, 및 상기 배기밸브를 제어하는 제어부를 포함하고, 상기 제어부는 상기 실린더로 디젤연료를 공급하는 디젤모드 대비 상기 실린더로 가스연료를 공급하는 가스모드에서 상기 배기밸브의 폐쇄타이밍을 소정 시간 지연시키는 것을 특징으로 하는 선박용 이중연료엔진에 관한 것이다.

    The present invention relates to an engine for a ship, which includes: a cylinder providing a space for combusting fuel; a piston reciprocating between a top dead point and a bottom dead point in the cylinder; and a supplier coupled to the cylinder, the supplier supplying the fuel and air to the cylinder. The supplier includes: a fuel supply apparatus supplying the fuel to the cylinder; and an air supply apparatus supplying the air to the cylinder. The air supply apparatus includes an auxiliary air supply member supplying the air to the cylinder between a lower side and an upper side of the cylinder. The auxiliary air supply member supplies the air together with the fuel when the fuel is supplied by the fuel supply apparatus while the piston is being moved from the dead point to the top dead point.
