Abstract
본 발명은 자동차엔진의 가변압축비 실린더헤드에 관한 것으로, 종래에는 연료의 변경에 연소실의 압축비 변경이 용이치 않고 엔진생산라인에서의 각 실린더의 품질편차나 엔진의 노후시 실린더들간의 압축압력의 차이심화로 인한 엔진의 부조현상 등이 발생되었다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a variable compression ratio cylinder head for an automobile engine. In the past, it has been difficult to change the compression ratio of the combustion chamber to change the fuel, And the engine has suffered a collision due to deepening.
이에 본 발명은 예시도면 제2도 및 제3도에서와 같이 실린더헤드(12)의 내측에 가변체적부(14)를 형성하고, 상기 가변체적부(14)에 피스톤(16)을 밀착시키며, 작동수단(18)에 의해 상기 피스톤(16)을 조정하여 상기 가변체적부(14)의 범위내에서 연소실의 체적을 변화시켜 최적의 압축비를 유지케 함으로써 상기 문제점을 해소한 것이다.2 and 3, the present invention is characterized in that the variable volume portion 14 is formed inside the cylinder head 12, the piston 16 is brought into close contact with the variable volume portion 14, The problem is solved by adjusting the piston 16 by the operating means 18 to change the volume of the combustion chamber within the range of the variable volume portion 14 to maintain the optimum compression ratio.
Description
