Abstract

본 발명은 흡기행정으로 유입되는 공기와 별도 분사되는 연료가 강한 텀블 유동과 스월 유동으로 혼합됨과 동시에 피스톤이 상승되는 과정에서도 텀블은 물론 강력한 스월 유동이 깨지지 않음으로써, 희박 연소를 구현할 수 있도록 한 내연기관을 제공함에 그 목적이 있다.According to the present invention, the air flowing into the intake stroke and the fuel injected separately are mixed in a strong tumble flow and a swirl flow, and at the same time, a powerful swirl flow is not broken in the process of raising the piston, so that lean combustion can be realized. The purpose is to provide an institution.

이를 실현하기 위하여 연소실의 상면 중앙으로 점화 플러그가 배치되고, 그 양측으로 흡,배기 포트가 형성되며, 실린더의 내부에 피스톤이 상하 슬라이드 가능하게 결합되는 구성을 갖는 내연기관에 있어서, 상기 피스톤의 상면에 경사면이 피스톤의 원주방향을 향하는 돌기부를 형성하고, 이의 돌기부 경사면에 피스톤의 원주방향에 따른 호형의 반원형 안내홈을 형성하며, 상기 안내홈의 상단부가 직선 왕복 운동하는 궤적상의 실린더 상측부에 연료 인젝터를 배치하여 이루어지는 내연기관을 제공한다.In an internal combustion engine having a configuration in which a spark plug is disposed at the center of the upper surface of the combustion chamber, inlet and exhaust ports are formed at both sides thereof, and the piston is slidably coupled to the inside of the cylinder, the upper surface of the piston. The inclined surface is formed in the circumferential direction of the piston, the projection is formed in the inclined surface arc-shaped semi-circular guide grooves along the circumferential direction of the piston, the upper end of the guide groove in the upper cylinder of the trajectory on the trajectory linearly Provided is an internal combustion engine comprising an injector.
