Abstract

본 발명은 차량의 엔진 피스톤에 관한 것으로, 톱 피스톤 링과 상기 톱 피스톤 링을 장착시키는 링 그루브를 구비하는 블로바이 가스 조절용 피스톤은, 상기 톱 피스톤 링(34)이 상기 링 그루브(36)에 장착되었을 때, 상기 링 그루브(36)의 후방 틈새가 상기 링 그루브(36)의 전방 틈새보다 크며, 상기 링 그루브(36)의 전방 하단부에는 라운드부(38)가 형성되는 것을 특징으로 한다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an engine piston of a vehicle, wherein a blow-by gas regulating piston including a top piston ring and a ring groove for mounting the top piston ring, wherein the top piston ring 34 is mounted to the ring groove 36. When it is, the rear gap of the ring groove 36 is larger than the front gap of the ring groove 36, the front lower portion of the ring groove 36 is characterized in that the round portion 38 is formed.
