상기한 인젝터 튜브는 연소실측에서 폭발한 폭발력이 인젝터 튜브에 작용하므로서 시일링이 떨어지면서 가스등의 누설이 발생하고, 냉각수의 유입이 우려되는 등 문제점이 있다.The injector tube has a problem in that the explosion force exploded on the combustion chamber side acts on the injector tube, causing the leakage of gas, etc. as the sealing drops, and the inflow of the cooling water is concerned.

따라서 본 발명은 앞에서 언급한 바와 같은 문제점을 해결하기 위하여 발명된 것으로서, 본 발명의 목적은 연소실측 실린더 헤드에 조립되는 인젝터 튜브를 개선하여 시일링이 증대되게 한 차량의 엔진내 가스 누설 방지용 인젝터 튜브를 제공하는데 있다.Accordingly, the present invention has been invented to solve the above-mentioned problems, and an object of the present invention is to improve the injector tube assembled in the combustion chamber cylinder head so that the sealing is increased, the injector tube for preventing gas leakage in the engine of the vehicle To provide.

도1은 종래기술에 따른 인젝터 튜브가 적용됨을 도시한 도면.1 is a view showing that the injector tube according to the prior art is applied.

도2는 본 발명에 따른 인젝터 튜브를 도시한 도면.2 shows an injector tube according to the invention.

이를 실현하기 위한 본 발명은The present invention for realizing this

차량의 엔진용 인젝터 튜브에 있어서,In the injector tube for an engine of a vehicle,

인젝터 튜브의 조립이 이루어지는 연소실측 실린더 헤드에 조립홈을 형성한 조립공과,An assembling hole in which an assembling groove is formed in the combustion chamber-side cylinder head where the injector tube is assembled

상기 조립공의 조립홈과 일치하게 확관되어 형성되는 조립턱에 의해 기밀하게 조립되는 조립관부를 형성하여 이루어지는 차량의 엔진용 인젝터 튜브를 제공하는데 있다.The present invention provides an injector tube for an engine of a vehicle formed by forming an assembly tube part which is airtightly assembled by an assembly jaw that is formed to be expanded to coincide with an assembly groove of the assembly hole.

본 발명은 디젤엔진의 연소실측 실린더 헤드에 형성한 조립공에 조립홈을 형성하고 인젝터 튜브의 조립관부를 삽입하여 확관하므로서 조립턱을 형성하게 되어 가스 누출과 냉각수의 누수등이 방지되게 된다.The present invention forms an assembling jaw by forming an assembling groove in the assembling hole formed in the combustion cylinder side cylinder head of the diesel engine and inserting and expanding the assembling tube part of the injector tube to prevent gas leakage and leakage of cooling water.

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 인젝터 튜브를 도시한 도면이고, 차량의 엔진용 인젝터 튜브(20)는 인젝터 튜브의 조립이 이루어지는 연소실(22)측 실린더 헤드(24)에 형성한 조립공(26)에 조립홈(28)을 형성하고 있다.2 is a view showing an injector tube according to the present invention, wherein the engine injector tube 20 of the vehicle is assembled to an assembling hole 26 formed in the cylinder head 24 on the combustion chamber 22 side where the injector tube is assembled. The groove 28 is formed.

상기 조립공(26)의 조립홈(28)과 일치하게 확관되어 형성되는 조립턱(30)에 의해 기밀하게 조립되는 조립관부(32)를 형성하여 이루어지고 있다.It is made by forming an assembly tube part 32 to be airtightly assembled by the assembly jaw 30 is formed to expand and coincide with the assembly groove 28 of the assembly hole (26).

상기한 바와 같이 이루어지는 본 발명의 작용을 설명하면, 디젤엔진의 연소실(22)측 실린더 헤드(24)에 형성한 조립공(26)에 조립홈(28)을 형성한다.When explaining the operation of the present invention made as described above, the assembling groove 28 is formed in the assembling hole 26 formed in the cylinder head 24 on the combustion chamber 22 side of the diesel engine.

상기 조립공(26)에 인젝터 튜브(20)의 조립관부(32)를 삽입하는데, 이때는 확관이 이루어지지 않은 상태의 조립관부(32)의 삽입이 이루어진다.The assembly tube part 32 of the injector tube 20 is inserted into the assembly hole 26. In this case, the assembly tube part 32 is not inserted into the assembly tube part 32.

상기한 조립관부(32)가 삽입되면 확관기를 사용하여 확관하므로서 조립홈()에 일치하게 되는 조립턱(30)을 형성하게 된다.When the assembly pipe part 32 is inserted, the assembly jaw 30 is formed to be matched with the assembly groove () by expanding by using the expander.

상기한 실린더 헤드(24)의 조립공(26)에 인젝터 튜브(20)의 기밀하게 조립하므로서 가스 누출과 냉각수의 누수등이 방지되게 된다.The airtight assembly of the injector tube 20 to the assembly hole 26 of the cylinder head 24 prevents gas leakage and leakage of cooling water.

연소실의 폭발력이 인젝터 튜브에 미치더라도 조립홈과 조립턱에 의해 조립이 이루어지기 때문에 기밀한 시일링이 이루어져 제품의 신뢰성을 확보하게 된다.Even though the explosive force of the combustion chamber reaches the injector tube, the assembly is made by the assembly groove and the assembly jaw, so that the airtight sealing is performed to secure the reliability of the product.
