Description

내연기관의 인젝션 노즐용 가이드 튜브Guide tube for injection nozzle of internal combustion engine

제1도는 종래의 가이드 튜브의 단면도1 is a cross-sectional view of a conventional guide tube

제2도는 본 고안의 가이드 튜브의 단면도2 is a cross-sectional view of the guide tube of the present invention

제3도는 본 고안의 가이드 튜브가 실린더 헤드에 조립된 단면도3 is a cross-sectional view of the guide tube of the present invention assembled to the cylinder head

본 고안은 내연기관의 인젝션 노즐용 가이드 튜브에 관한 것으로, 특히 냉각수 통로의 냉각수가 가이드 튜브와 실린더 헤드 사이를 통하여 누수되는 것을 방지하도록 한 내연기관의 인젝션 노즐용 가이드 튜브에 관한 것이다.The present invention relates to a guide tube for injection nozzles of an internal combustion engine, and more particularly, to a guide tube for injection nozzles of an internal combustion engine to prevent the cooling water of the cooling water passage from leaking between the guide tube and the cylinder head.

종래의 가이드 튜브(I)는 제1도에서와 같이 구리파이프로 형성된 원통형으로 소지경의 전통부(10)와 대직경의 후통부(11)로 이루어져 있다. 이는 가이드 튜브(1)의 전통부(10)와 후통부(11)가 실린더 헤드(2)에 끼워넣은 다음 확관을 하여 실린더 헤드(2)에 밀착시켜 냉각수 통로(3)에 채워진 냉각수의 누수를 방지하게 되어 있다.[제3도에서 도면부호 4가 없는 상태]Conventional guide tube (I) is a cylindrical formed of copper pipes as shown in Figure 1, consisting of the traditional portion 10 of the small diameter and the rear cylinder portion 11 of a large diameter. This is because the traditional part 10 and the rear tube part 11 of the guide tube 1 are inserted into the cylinder head 2, and then expanded to closely contact the cylinder head 2 to prevent leakage of the coolant filled in the cooling water passage 3. [The state without reference numeral 4 in FIG. 3]

그러나 이와 같은 종래의 상태에 있어서는 기관의 연소에 따라 실린더 헤드의 열적팽창과 냉각수의 영향을 받는 가이드 튜브의 열적팽창의 차이로 인해 접촉된 상태에서 틈새가 발생하여 누수가 일어난다.However, in such a conventional state, a gap occurs in the contacted state due to the difference in thermal expansion of the cylinder head and thermal expansion of the guide tube affected by the cooling water as the engine burns, causing leakage.

이렇게 누수가 발생되면 냉각수 통로로 새로운 냉각수가 들어와서 실린더헤드의 냉각이 진행되어 결국 실린더 내부의 연소가 불완전 연소가 된다. 이에 따라 기관의 성능에 약영향이 미치고, 불완전 연소로 인해 발생된 배기가스의 유해물질이 대기 여염을 일으키게 된다.When the leak occurs, new coolant enters the coolant passage and the cylinder head is cooled, resulting in incomplete combustion of the inside of the cylinder. As a result, the performance of the engine is weakly affected, and harmful substances in the exhaust gas generated due to incomplete combustion cause air flames.

본 고안은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 그 목적은 가이드 튜브와 실린더 헤드사이의 누수를 방지할 수 있도록 한 내연기관의 인젝션 노즐용 가이드 튜브를 제공함에 있다.The present invention has been made to solve the above problems, the object is to provide a guide tube for the injection nozzle of the internal combustion engine to prevent leakage between the guide tube and the cylinder head.

상기의 목적을 달성하기 위한 본 고안의 구체적인 수단은 내연기관의 실린더 헤드에 조립되는 가이드 튜브는 실린더헤드와 접촉되는 대응부위에 실링재를 코팅처리하여 냉각수통로의 누수를 방지할 수 있도록 한 것을 특징으로 한다. 또 상기 가이드 튜브는 내열성 고무를 코팅처리 한것을 특징으로 한다.Specific means of the present invention for achieving the above object is characterized in that the guide tube is assembled to the cylinder head of the internal combustion engine is coated with a sealing material in contact with the cylinder head to prevent leakage of the cooling water passage do. In addition, the guide tube is characterized in that the coating treatment of the heat-resistant rubber.

이하 청부된 도면을 참조하여 실시예를 상세히 설명하면 다음과 같다.Hereinafter, exemplary embodiments will be described in detail with reference to the accompanying drawings.

본 고안은 제2도 및 제3도에서와 같이 열팽창을 극히 최소화하는 실링재(Sealing Material)(4)를 실린더헤드(2)의 조립부위에 해당되게 가이드 튜브(1)의 소직경부(10)와 대직경부(11)에 코팅되어 있다.The present invention has a sealing material (4) that minimizes thermal expansion as shown in Figures 2 and 3 and the small diameter portion 10 of the guide tube (1) to correspond to the assembly portion of the cylinder head (2) It is coated on the large diameter part 11.

또한 상기 실링재에 대체하여 내열성 고무를 코팅재로 사용하여도 좋다. 이후 가이드 튜브(1)를 실린더 헤드(2)에 끼워 맞추어 완전히 밀착시킴으로서 접촉면이 기밀을 유지한 상태로 조립이 완료된다.In addition, a heat resistant rubber may be used as the coating material in place of the sealing material. Thereafter, the guide tube 1 is fitted to the cylinder head 2 to be in close contact, thereby completing the assembly while the contact surface is kept airtight.

이와 같이 설치된 본 고안의 기관의 연소가 진행될 시 가이드 튜브(1)와 실린더 헤드(2)와의 열적팽창의 차이는 가이드 튜브(1)와 실린더 헤드(2)와의 접촉된 상태에 있는 실링재(4)에 의해 보존됨으로서 냉각수통(3)에 채워진 냉각수가 실린더 헤드(2)에서 누수되는 일은 없다.The difference in thermal expansion between the guide tube 1 and the cylinder head 2 when the combustion of the engine of the present invention installed as described above proceeds is the sealing material 4 in contact with the guide tube 1 and the cylinder head 2. By being preserve | saved by this, the cooling water filled in the cooling water container 3 does not leak in the cylinder head 2.

상술한 바와 같이 구성되고 작용되는 본 고안은 실린더 헤드와 가이드 튜브와의 누수를 가이드 튜브에 실링재 또는 내열성 고무의 코팅을 함으로써 냉각수의 누수를 방지하여 기관 성능의 악화 및 불완전연소의 상태를 방지할 수 있는 효과가 있다.The present invention constructed and operated as described above can prevent leakage of the coolant by coating a sealant or heat-resistant rubber on the guide tube with leakage of the cylinder head and the guide tube, thereby preventing deterioration of engine performance and incomplete combustion. It has an effect.
