Abstract: 본 발명은 자동차 엔진용 실린더 헤드 구조에 관한 것으로서, 플러그 장착홀의 형상을 변경하여 배기포트와 플러그 장착홀 사이의 두께를 증대시키고, 두께가 증대된 배기포트와 플러그 장착홀 사이의 공간에 워터 자켓을 보다 깊게 형성하여 구성함으로써, 워터 자켓의 냉각 효과가 상승됨에 따라 엔진 운전 중 실린더 헤드 금속면의 온도, 특히 배기포트 및 플러그 장착홀 주위 금속면의 온도가 크게 낮아질 수 있고, 이에 내구 신뢰성이 더욱 향상되어지는 자동차 엔진용 실린더 헤드 구조에 관한 것이다. 이러한 본 발명의 실린더 헤드 구조는, 배기포트와 플러그 장착홀 사이의 두께가 증대될 수 있도록, 플러그 장착홀 상단에 마련된 플러그 좌면부의 상하 구간 길이를 짧게 형성하고, 이와 함께 플러그 장착홀의 태핑 가공부를 상측으로 길게 연장 형성하는 한편, 두께가 증대된 배기포트와 플러그 장착홀 사이의 공간에서 워터 자켓의 깊이가 증대될 수 있도록 워터 자켓 하단부가 태핑 가공부 상단 높이 아래까지 깊게 연장 형성되어 있는 것을 특징으로 한다.

Abstract: PURPOSE: A tension apparatus of a timing belt for a vehicle is provided to lengthen a life span by reducing stress with applying tensile force according to pressure of engine oil in driving the engine, and to cut down expenses by reducing parts. CONSTITUTION: A tensioner(20) of a timing belt(10) is composed of a body(22) arranging plural cylinders(22a) radially and circumferentially, and having an oil supply passage(22b) connected to the cylinder; plural pistons(24) inserted to cylinders; plural elastic members(26) supporting pistons; a tension pulley(28) supported by elastic force equal to the elasticity in the end of the piston; and the timing belt receiving tensile force from pressure of engine oil supplied through the oil passage in operating the engine. Tensile force is automatically adjusted against the timing belt according to supply of engine oil.
