Abstract

본 발명은 차량엔진의 실린더에 장착되는 와류발생용 피스톤에 관한 것으로, 연소실(4) 내부로 유입되는 혼합기와 연소실(4) 내부에서 배출되는 배기가스에 와류를 발생시키기 위하여, 상기 피스톤의 피스톤헤드(3)는 상부 피스톤헤드(3a)와 하부피스톤헤드(3b)로 이중분할되어 이루어지되 이 상부피스톤헤드(3a)와 하부피스톤헤드(3b)는 베어링(7)을 매개로 서로 장착되며, 이 상부피스톤헤드(3a)에 연결핀(8)이 피스톤헤드(3)에 연결설치되고, 이들 상·하부 피스톤헤드(3a,3b)의 바깥둘레면에 형성된 보올나사형성부(9a)가 실린더라이너(2)에 형성대응된 보올나사형성부(9b)에 요철형태로 맞물려 설치됨에 따라 연소실(4)로 유입되는 혼합기와 배출되는 배기가스에 이 회전되는 피스톤헤드(3)에 의해서 와류가 발생되어 불완전연소를 방지하여 환경오염의 방지와 엔진성능의 향상을 도모할 수 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vortex generating piston mounted to a cylinder of a vehicle engine, and to generate vortices in a mixer flowing into the combustion chamber 4 and exhaust gas discharged from the combustion chamber 4, the piston head of the piston. (3) is divided into an upper piston head (3a) and a lower piston head (3b) is made of the upper piston head (3a) and lower piston head (3b) is mounted to each other via a bearing (7), A connecting pin 8 is connected to the piston head 3 to the upper piston head 3a, and the bowl screw forming portion 9a formed on the outer circumferential surface of the upper and lower piston heads 3a and 3b is a cylinder liner. (2) vortex is generated by the piston head (3) rotated to the mixer and the exhaust gas discharged into the combustion chamber (4) as it is installed in the concave-convex shape to the bowl screw forming portion (9b) corresponding to the formation. To prevent incomplete combustion and to prevent environmental pollution The engine performance can be improved.
