Abstract

본 발명은 배기가스 저감용 엔진의 실린더에 관한 것으로서, 특히 피스톤이 하사점에 있을때 세컨드 피스톤링(SECOND PISTON RING)의 윗쪽까지 연결되는 가는 홈을 피스톤의 전방과 후방에 접촉하는 실린더 부분에 형성하므로써 폭발행정의 말기와 배기행정의 초기에 발생하는 역류가스(BLOW BACK GAS)를 감소시키므로 엔진에서 발생하는 유해배기가스의 발생량을 감소시킨 효과가 있는 배기가스 저감용 엔진의 실린더에 관한 것이다.The present invention relates to a cylinder of an engine for reducing exhaust gas, and in particular, by forming a thin groove connected to the upper side of the second piston ring when the piston is at the bottom dead center in the cylinder portion in contact with the front and rear of the piston. The present invention relates to a cylinder of an exhaust gas reduction engine having an effect of reducing the amount of harmful exhaust gas generated in an engine since the blowback gas generated at the end of the explosion stroke and the beginning of the exhaust stroke is reduced.

Description

배기가스 저감용 엔진의 실린더Cylinder of engine for exhaust gas reduction

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 역류가스(BLOW-BACK) 저감을 위한 가는 홈이 링 그루브에 형성된 것을 보여주는 종래의 엔진의 실린더 단면도,1 is a cross-sectional view of a cylinder of a conventional engine showing that the groove is formed in the ring groove for reducing the BLOW-BACK,

제2도는 실린더의 하단으로 부터 피스톤의 톱 링과 세컨드 링 사이까지 가는 홈이 실린더 벽에 형성된 것을 보여주는 본 고안의 배기가스 저감용 엔진의 실린더 다면도,FIG. 2 is a cylinder side view of the exhaust gas reducing engine of the present invention showing that grooves from the bottom of the cylinder to the top ring and the second ring of the piston are formed in the cylinder wall.

제3도는 인터 링 공간에 가는 홈과 같은 역류가스의 통로가 형성되어 있지 않을때, 연소실 압력과 인터 링 공간의 압력을 보여주는 그래프.3 is a graph showing the combustion chamber pressure and the pressure in the interring space when no passage of backflow gas such as a groove into the interring space is formed.
