Abstract

본 발명은 압축비 증가에 따른 노킹방지를 위한 실린더 헤드에 관한 것으로, 특히 실린더 헤드에 별도의 가변 피스톤을 설치하여 연소실의 용적을 변화시킬 수 있도록 함으로써, 압축비의 상승에 따른 노킹을 방지할 수 있도록 한 압축비 증가에 따른 노킹방지를 위한 실린더 헤드로, 실린더 헤드(1) 일측 벽면에 단턱부(11)그 형성된 관통구멍(10)과; 이 관통구멍(10)의 단턱부(11)에 설치되는 가변 피스톤(20)과; 이 가변피스톤(20)의 일단에 설치되는 커넥팅로드(30)와; 이 커넥팅로드(30) 일단에 설치된 돌기부(31)에 걸어맞춤되기 위한 가변홈(41)이 가장자리에 형성되며 엔진의 점화 직전에 상기 가변피스톤(20)을 작동시켜 연소실 내의 용적을 변화시키는 가변캠(40)으로 구성된다.The present invention relates to a cylinder head for preventing knocking due to an increase in compression ratio, and in particular, a variable piston is provided in a cylinder head to change a volume of a combustion chamber, thereby preventing knocking A cylinder head for preventing knocking caused by an increase in compression ratio, the cylinder head comprising: a through hole (10) formed with a step portion (11) at one side wall surface of the cylinder head; A variable piston (20) provided on the step (11) of the through hole (10); A connecting rod (30) installed at one end of the variable piston (20); A variable cam 41 for engaging with a protrusion 31 provided at one end of the connecting rod 30 is formed at the edge and a variable cam 20 for changing the volume in the combustion chamber by operating the variable piston 20 immediately before ignition of the engine, (40).
