본 발명은 차량용 엔진에 있어서 실린더헤드 내지는 흡기매니폴드에 설치되는 연료장치의 일부인 인젝터(Injector)의 둘레부위로 공기를 불어 넣을 수 있도록 되어 있는 인젝터 장착구조에 관한 것으로, 특히 엔진의 실린더헤드 내지는 흡기매니폴드를 통해 전달되는 열로 부터 인젝터의 성능저하를 방지할 뿐만 아니라 실린더헤드 설치부위의 가공부담을 저감시킨 엔진에 있어서 연료분사장치의 인젝터 장착구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an injector mounting structure in which air can be blown around a part of an injector which is a part of a fuel device installed in a cylinder head or an intake manifold in a vehicle engine, and in particular, a cylinder head or intake of an engine The present invention relates to an injector mounting structure of a fuel injection device in an engine which not only prevents the performance of the injector from the heat transmitted through the manifold, but also reduces the processing burden on the cylinder head mounting portion.
일반적으로 연료분사장치의 인젝터는 실린더헤드 내지는 흡기 매니폴드에 보유지지되어 흡기매니폴드를 통해 유입된 공기속으로 연료를 분사시켜 혼합기를 만드는 역할을 수행하는바, 이와같은 인젝터의 종래 장착구조는 제 3도에 도시된 바와같이 흡기매니폴드 내지 실린더헤드(102)에서 이 인젝터(103)의 둘레부를 보유지지시키기 위해 공기구멍(108)을 갖춘 이 실린더헤드(102)의 연줄선단부위(102a)를 여러 단이 지게 가공시키고 이 단이진 부위에 시일링재(106)들을 매개로 상기 인젝터(103)를 직접 부착시키는 구조로 되어 있다.In general, the injector of the fuel injection device is held in the cylinder head or the intake manifold to inject fuel into the air introduced through the intake manifold to make a mixer. As shown in FIG. 3, the inlet manifold 102a of the cylinder head 102 with the air hole 108 is provided to hold the circumference of the injector 103 in the intake manifold or the cylinder head 102. As shown in FIG. Several stages are forged, and the injector 103 is directly attached to the stage of the stage through the sealing material 106.
그러나 이러한 종래 인젝터 장착구조는 상기 실린더헤드(102)로 부터 전달되는 고열이 인젝터(103)에 직접 영향을 줌에 따라 이 인젝터의 성능이 저하되고, 더욱이 상기 실린더헤드(102)의 연결선단부위(102a)가 여러단 형태로 가공되어짐으로서 가공부담이 증가되어지는 단점을 지니게 되었다.However, in the conventional injector mounting structure, as the high heat transmitted from the cylinder head 102 directly affects the injector 103, the performance of the injector is deteriorated, and moreover, the connection tip portion of the cylinder head 102 ( 102a) has the disadvantage that the processing burden is increased because it is processed in a multi-stage form.
이에 본 발명은 상기와 같은 종래의 문제점을 해결한 것으로, 실린더헤드에 접하는 인젝터의 단열이 효과적으로 수행되어질 뿐만 아니라 인젝터가 설치되는 실린더헤드 연결선단부의 가공도 용이하게 이루어지는 엔진에 있어서 연료부사장치의 인젝터 장착구조를 제공함에 그 목적이 있다.Accordingly, the present invention solves the above-described problems, and the injector of the fuel injection device in the engine that not only effectively insulates the injector in contact with the cylinder head, but also facilitates the machining of the cylinder head connection tip on which the injector is installed. The purpose is to provide a mounting structure.
상기와 같은 목적을 달성하기 위한 본 발명은, 실린더헤드의 설치연결선단부에 공기갤러리를 형성시키고 이 설치연결선단부에는 공기갤러리에 연통되는 여러개의 공기구멍을 갖춘 단열재인 안내부가 설치되며, 이 안내부에 공지의 시일링재들을 매개로 인젝터가 장착되어진다.In order to achieve the above object, the present invention forms an air gallery at the installation connecting tip of the cylinder head, and the installation connecting tip is provided with a guide having insulation material having a plurality of air holes communicating with the air gallery. The injector is mounted on a known sealing material.
이하, 본 발명은 첨부된 예시도면에 의거 상세히 설명하낟.Hereinafter, the present invention will be described in detail based on the accompanying drawings.
본 발명에 따른 인젝터 장착구조는 제 1도와 제 2도에 도시된 바와같이 엔진(1)의 실린더헤드(2) 내지는 흡기매니폴드에 연료를 분사시키는 인젝터(3)가 흡기관(4)에 설치되되, 이 인젝터(3)는 실린더헤드(2)의 설치연결선단부(2a)에 장착되는 단열재 재질인 안내부(5)에서 시일링재(6)들을 매개로 설치되어져 있다.The injector mounting structure according to the present invention has an injector (3) installed in the intake pipe (4) for injecting fuel into the cylinder head (2) or the intake manifold of the engine (1) as shown in FIGS. However, the injector 3 is installed through the sealing member 6 in the guide portion 5 which is a heat insulating material mounted on the installation connecting tip 2a of the cylinder head 2.
여기서 상기 실린더헤드(2)에 형성된 공기갤러리(7)는 안내부(5)에 형성된 공기구멍(8)에 정렬되어 인젝터(3)의 공기둘레부(3a)까지 연통되어진다.In this case, the air gallery 7 formed in the cylinder head 2 is aligned with the air hole 8 formed in the guide part 5 so as to communicate with the air circumferential part 3a of the injector 3.
그리고 상기 인젝터(3)는 단열재인 안내부(5)를 매개로 실린더헤드(2)의 설치연결선단부(2a)에 장착되어지고, 이 안내부(5)둘레에 형성된 여러개의 공기구멍(8)들이 실린더헤드(2)의 공기갤러리(7)에 연통되어져 있으므로 공기는 이 공기갤러리(7)와 공기구멍(8)들을 통해서 인젝터(3)의 공기둘레부(3a)로 유입되어진다.The injector 3 is mounted to the installation connecting tip 2a of the cylinder head 2 via the guide part 5, which is a heat insulating material, and has several air holes 8 formed around the guide part 5, respectively. Air is introduced into the air circumferential portion 3a of the injector 3 through the air gallery 7 and the air holes 8 since the air is communicated with the air gallery 7 of the cylinder head 2.
상기와 같이 본 발명은 실린더헤드 내지는 흡기매니폴드에 인젝터가 단열재인 안내부를 매개로 장착됨에 따라 이 인젝터가 취부되는 실린더헤드의 설치연결선단부의 가공이 용이하게 이루어질 뿐만 아니라 상기 안내부로 인하여 실린더헤드를 통해 전달되는 열을 차단시켜 인젝터의 성능저하를 방지할 수가 있다.As described above, according to the present invention, as the injector is mounted on the cylinder head or the intake manifold through the guide part which is a heat insulator, the installation head of the cylinder head to which the injector is mounted is easily processed, and the cylinder head is formed by the guide part. By blocking the heat transmitted through it, the performance of the injector can be prevented.
