Abstract

본 발명은 더블 오버헤드 캠축 형식(DOHC)의 엔진에 있어서 실린더헤드에 장착되는 캠샤프트를 해체하지 않고도 실린더블럭에 조립 및 해체할 수 있도록 하는 자동차 엔진의 실린더헤드에 있어서의 갬샤프트 설치구조에 관한 것으로, 실린더헤드에 2열로 배열되는 보울트구멍과 흡기측 및 배기측 캠샤프트가 장착되는 두줄의 축수부를 형성하는 것에 있어 상기 배기측 캠샤프트가 장착되는 배기측 축수부를 그 하방에 위치하는 보울트구멍으로 삽입되는 보울트 삽입영역에 대하여 외측으로 벗어난 위치에 설치하여 실린더헤드를 실린더블럭에 조립 또는 해제할 때 배기측 캠샤프트를 해체하지 않고 조립 및 해체작업을 수행할 수 있도록 하는데 목적을 두고 있는 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a gasket shaft mounting structure in a cylinder head of an automobile engine which allows assembly and disassembly of a camshaft mounted on a cylinder head in a double overhead camshaft type (DOHC) engine without disassembling the camshaft. In the form of a bolt hole arranged in two rows in the cylinder head and two rows of bearing parts on which the intake side and the exhaust side camshafts are mounted, the exhaust hole bearing portion on which the exhaust side camshaft is mounted is provided as a bolt hole located thereunder. It is intended to be installed at a position outwardly with respect to the bolt insertion region to be inserted so that the assembly and dismantling operation can be performed without disassembling the exhaust side camshaft when assembling or releasing the cylinder head to the cylinder block.
