Abstract

(목적) 기관 저온시에서 연소실내에 운전 상태에 맞는 가스유동을 확보한다.(Objective) To ensure gas flow in the combustion chamber at low temperatures at engine low temperatures.

(구성) 흡기계에 에어 어시스트(13)를 설치함과 동시에, 소정의 절결부를 마련한 스왈 컨트롤 밸브(15)를 구비한 내연기관에 있어서, 기관의 운전 조건을 검출하는 수단고, 스왈 컨트롤 밸브(15)를 전개, 반개, 전폐의 각 위치에 구동가능한 액츄에이터(22)와 기관 온도가 소정치 보다 낮은 기관 저부하역에서 에어 어시스트 인젝터(13)의 에어 어시스트를 행하며, 스왈 컨트롤 밸브(15)를 전폐 위치에, 기관 온도가 소정치 이상의 기관 저부하역에서 에어 어시스트 인젝터(13)의 에어 어시스트를 정지하고, 스왈 컨트롤 밸브(15)를 반개 위치에, 이것들 이외의 운전역에 스왈 컨트롤 밸브(15)를 전개 위치로 제어하는 제어 수단을 마련함과 동시에 스왈 컨트롤 밸브(15)의 적어도 비절결부 측에 대한 흡입 통로(11) 내면을 스왈 컨트롤 밸브(15)의 전폐 위치에서 반개 위치까지 밸브(15)의 회전궤적에 따라서 형성한다.(Configuration) An internal combustion engine having a swirl control valve 15 provided with an air assist 13 in an intake machine and provided with a predetermined cutout portion, which is a means for detecting operating conditions of the engine, and a swirl control valve. Air assist of the air assist injector 13 is performed at the actuator 22 which can be driven to each position of the fully open, half open, and fully closed positions, and the engine temperature lower than the predetermined value, and the swirl control valve 15 is opened. In the fully closed position, the air assist of the air assist injector 13 is stopped at an engine low load station of which the engine temperature is equal to or higher than a predetermined value, and the swirl control valve 15 is opened at a half open position and a driving region other than these. While providing a control means for controlling the to the deployed position, the inner surface of the suction passage 11 at least on the non-cutout side of the swirl control valve 15 is half the position of the swirl control valve 15 in the fully closed position. To be formed according to the locus of swinging of the valve 15.
