Description

차량용 엔진의 플러그 실링구조{Plug sealing device of engine for car}Plug sealing device of engine for car

본 발명은 차량용 엔진의 플러그 실링구조에 관한 것으로서, 더욱 상세하게는 실린더 헤드에 형성된 워터 자켓과 통하여진 통공을 간편하게 실링할 수 있는 차량용 엔진의 플러그 실링구조에 관한 것이다.The present invention relates to a plug sealing structure of a vehicle engine, and more particularly to a plug sealing structure of a vehicle engine that can easily seal the through-holes through the water jacket formed in the cylinder head.

일반적으로 엔진운전시 고온,고압상태로 운전하게 될 경우 냉각시스템 즉, 냉각수 통로가 필요하다. 이를 위해 워터 자켓부 코어를 이용하여 실린더헤드를 주조하게 되는데, 상기 코어를 이용하여 주조하게 될 경우 코어 제거시 통공 발생하게 되며 소재상태를 홀을 가공하기 위해서는 플러그로 워터 자켓부 실링이 필요하다.In general, when operating at high temperature and high pressure during engine operation, a cooling system, that is, a cooling water passage is required. To this end, the cylinder head is cast using the water jacket portion core. When casting using the core, a hole is generated when the core is removed. In order to process the hole in the material state, the water jacket portion is required to be sealed with a plug.

종래에는 도 1에 나타낸 바와 같이 실린더헤드(100)에는 냉각수가 이동하는 워터 자켓(110)이 형성되어 있고, 그 워터 자켓(110)의 상측에는 통공(111)이 형성되어 있으며, 상기 통공(111)에는 플러그(120)가 나사 결합되어 있다.In the related art, as illustrated in FIG. 1, a water jacket 110 through which a coolant moves is formed in a cylinder head 100, a through hole 111 is formed above the water jacket 110, and the through hole 111 is formed. ), The plug 120 is screwed.

한편, 상기 워터 자켓(110)의 일측에는 인젝터 노즐(140)이 설치되어 있고, 그 실린더헤드(100)에는 인젝터 노즐(140)을 고정하기 위한 인젝터 클램프(130)가 설치되어 있으며, 상기 인젝터 클램프(130)의 일단은 플러그(120)의 상면에 접촉되 어 있다.Meanwhile, an injector nozzle 140 is installed at one side of the water jacket 110, and an injector clamp 130 is installed at the cylinder head 100 to fix the injector nozzle 140. One end of the 130 is in contact with the upper surface of the plug 120.

그리고, 상기 인젝터 클램프(130)는 고정볼트(150)를 매개로 견고히 고정되는 것으로서, 상기 고정볼트(150)에 의해서 인젝터 클램프(130)가 고정될 때 상기 인젝터 클램프(130)의 일단은 플러그(120)의 상면을 가압하는 것으로서 플러그(120)의 실링력을 향상시키게 되는 것이다.And, the injector clamp 130 is to be firmly fixed via the fixing bolt 150, one end of the injector clamp 130 when the injector clamp 130 is fixed by the fixing bolt 150 is a plug ( By pressing the upper surface of the 120 is to improve the sealing force of the plug (120).

그러나 이러한 종래의 구조는 플러그(120)를 통공(111)에 나사결합하게 되므로 나사결합부의 틈새를 통하여 냉각수가 유출되었으며, 이와 같이 냉각수가 유출되는 것을 방지하기 위하여 나사부에 접착제를 도포하는 경우도 있으나, 상기 접착제를 도포할 경우에는 장기간 사용시 고온의 냉각수에 의해서 접착제의 접착력이 감소하게 되므로 냉각수가 유출되는 등의 문제점이 있었다.However, in the conventional structure, the plug 120 is screwed into the through hole 111, so that the coolant flows out through the gap of the screw coupling part, and thus, an adhesive may be applied to the screw part to prevent the coolant from leaking. When the adhesive is applied, the adhesive force of the adhesive is reduced by the high temperature cooling water during long term use, such that the cooling water is leaked.

본 발명은 상기한 문제점을 해결하기 위하여 발명한 것으로서, 그 목적은 실린더헤드에 형성된 워터자켓에 통과 하여지게 형성된 통공에 플러그를 압입하여 상기 통공을 신속하게 실링함은 물론, 일정한 실링력을 유지하여 냉각수 유출을 미연에 방지할 수 있는 차량용 엔진의 플러그 실링구조를 제공함에 있다.The present invention is invented to solve the above problems, the purpose is to press the plug into the through-hole formed to pass through the water jacket formed in the cylinder head to quickly seal the through hole, as well as maintaining a constant sealing force An object of the present invention is to provide a plug sealing structure of a vehicle engine that can prevent cooling water leakage in advance.
