Abstract

PURPOSE: A tumble inducing engine is provided to improve the assembling position of a fuel injector with a tumble injection using an intake port. CONSTITUTION: A tumble inducing engine(20) installs a fuel injector(24) between exhaust ports(22) using an adapter made from ceramic. Then, the fuel injector is firmly fixed between the exhaust ports installing an exhaust manifold to prevent fuel leakage caused by high temperature exhaust gas. An intake port(30) hits on a cylinder wall to generate a tumble and the fuel injector injects fuel so that combustion efficiency is enhanced and exhaust gas is reduced.

도2는 본 발명에 따른 텀블 유도형 엔진을 도시한 도면.Figure 2 shows a tumble induction engine according to the present invention.

도3은 도2의 본 발명에 따른 인젝터가 적용됨을 도시한 도면.Figure 3 shows that the injector according to the invention of Figure 2 is applied.

이를 실현하기 위한 본 발명은The present invention for realizing this

텀블 유도형 엔진에 있어서,In the tumble induction engine,

배기포트의 사이사이에 연료를 분사하게 연료 인젝터를 단열재질의 아답터로 설치하여 이루어지는 텀블 유도형 엔진을 제공하는데 있다.The present invention provides a tumble induction engine in which a fuel injector is installed as an insulating material adapter to inject fuel between exhaust ports.

본 발명은 통상의 텀블 유도형 엔진의 배기 매니폴드와 배기포트 사이 사이에 연료 인젝터를 세락믹재의 아답터를 이용 설치하므로서 고온인 배기가스에 의한 인젝터부위의 연료누출을 차단하게 되어 화재발생등을 방지하게 된다.According to the present invention, a fuel injector is installed between an exhaust manifold and an exhaust port of a conventional tumble induction engine using a ceramic adapter to block fuel leakage at an injector part due to high temperature exhaust gas, thereby preventing fire. Done.

이하 본 발명의 바람직한 구성 및 작용을 첨부한 도면에 의거하여 보다 상세하게 설명하면 다음과 같다.Hereinafter, the preferred configuration and operation of the present invention will be described in detail with reference to the accompanying drawings.

도2는 본 발명에 따른 텀블 유도형 엔진을 도시한 도면이고, 도3은 도2의 본 발명에 따른 인젝터가 적용됨을 도시한 도면이다.2 is a view showing a tumble induction engine according to the present invention, Figure 3 is a view showing that the injector according to the present invention of FIG.

텀블 유도형 엔진(20)은 배기포트(22)의 사이 사이에 연료를 분사하게 연료 인젝터(24)를 세라믹 재질의 아답터(26)로 설치하여 이루어지고 있다.The tumble induction engine 20 is formed by installing a fuel injector 24 with an adapter 26 made of a ceramic material to inject fuel between the exhaust ports 22.

상기한 바와 같이 이루어지는 본 발명의 작용은 텀블 유도형 엔진(20)의 배기 매니폴드(28)가 설치되는 배기포트(22) 사이 사이에 연료 인젝터(24)를 세락믹재의 아답터(26)를 이용 고정 설치하므로서 고온인 배기가스에 의한 인젝터(24)부위의 연료누출을 차단하게 되어 화재발생등을 방지하게 된다.The operation of the present invention made as described above uses the fuel injector 24 between the exhaust port 22 where the exhaust manifold 28 of the tumble induction engine 20 is installed, using the adapter 26 made of ceramic material. By the fixed installation, the fuel leakage of the injector 24 by the high temperature exhaust gas is blocked to prevent the occurrence of fire.

즉, 흡기포트(30)를 유입되는 공기는 실린더 벽에 부딪쳐 텀블을 일으킬 때 배기포트(22)측에 설치된 연료 인젝터(24)에서 연료 분사가 이루어지게 하므로서 연소효율을 증대와 더불어 배기가스 저감이 이루어진다.That is, when the air flowing into the intake port 30 hits the cylinder wall and causes tumble, fuel injection is performed at the fuel injector 24 installed on the exhaust port 22 side, thereby increasing combustion efficiency and reducing exhaust gas.
