Description
본 고안은 자동차용 배기매니폴드에 관한 것으로, 좀더 상세히 설명하면 실린더헤드에 부착되는 배기메니폴드의 외주면에 일정간격으로 형성된 결합부를 개선하여 배기매니폴드를 실린더헤드에 결합시켜 주는 결합보울트의 축력변화를 감소시켜 배기가스의 유출을 방지할 수 있도록 한 자동차용 배기매니폴드에 관한 것이다.The present invention relates to an exhaust manifold for automobiles. In detail, the axial force change of the coupling bolt for coupling the exhaust manifold to the cylinder head is improved by improving the coupling portion formed at a predetermined interval on the outer circumferential surface of the exhaust manifold attached to the cylinder head. An exhaust manifold for automobiles is provided so as to prevent the leakage of exhaust gas.
일반적으로 배기매니폴드는 이그저스트 매니폴드 또는 배기다기관이라고 지칭되는 것으로, 각 실린더로부터 배기가스를 모아 배기파이프로 보내는 관으로서, 자동차의 엔진성능에 따라 약간의 차이는 있으나 배출되는 배기가스의 온도는 1000℃ 이상이 되므로, 내열초합금으로 제작되고 있다Exhaust manifolds are generally referred to as exhaust manifolds or exhaust manifolds. The exhaust manifolds collect exhaust gas from each cylinder and send it to the exhaust pipe. The exhaust gas temperature varies slightly depending on the engine performance of the vehicle. Is made of heat-resistant superalloy since it becomes 1000 ℃ or more
예시도면 도 1 은 종래 배기매니폴드의 부착위치를 나타낸 예시도로서, 배기매니폴드(1)는 엔진의 상측부 일측면에 결합보울트(2)를 이용하여 부착이 되는 것으로서, 상기 엔진은 실린더헤드(3)와 실린더블록(4)으로 이루어져 있으며, 실린더헤드(3)의 양측면에는 실린더블록(4)에 형성된 피스톤이 직선운동하는 실린더수와 동일한 흡입구와 배출구가 형성되어 있다.Exemplary drawings Figure 1 is an exemplary view showing the attachment position of the conventional exhaust manifold, the exhaust manifold (1) is attached to one side of the upper side of the engine using a coupling bolt (2), the engine is a cylinder head (3) and the cylinder block (4), both sides of the cylinder head (3) is formed with the same inlet and outlet as the number of cylinders in which the piston formed in the cylinder block (4) linearly moving.
또한, 상기 실린더헤드(3)의 상측과 실린더블록(4)의 하측에 각각 실린더헤드커버(5)와 오일팬(6)이 부착되어 일체를 이루게 되고, 실린더헤드(3)와 실린더블록(4)에는 도면상 미도시 되었으나 각각 캠축과 크랭크축이 내설되어 실린더블록(4)의 상부에 설치되어 있는 피스톤의 상.하 직선운동을 회전운동으로 전환시켜 자동차의 구동력을 발생시키게 된다.In addition, the cylinder head cover 5 and the oil pan 6 are attached to the upper side of the cylinder head 3 and the lower side of the cylinder block 4, respectively, to form a unit, and the cylinder head 3 and the cylinder block 4 Although not shown in the drawings, respectively, the camshaft and the crankshaft are internally installed to generate a driving force of the vehicle by converting the up and down linear movement of the piston installed on the upper portion of the cylinder block 4 to the rotational movement.
이때 피스톤의 상.하 직선운동은 캠축이 회전하면서 흡기밸브와 배기밸브를 작동시켜 공기와 혼합된 연료를 흡입하고, 실린더의 상부에 형성된 연소실의 배기가스를 배출시키게 된다.At this time, the up and down linear movement of the piston operates the intake valve and the exhaust valve while the cam shaft rotates to suck the fuel mixed with the air, and discharge the exhaust gas of the combustion chamber formed on the upper portion of the cylinder.
상기 연소실의 배기가스는 엔진의 종류 가솔린 엔진 또는 디젤엔진에 따라 전기적 스파크와 흡입된 연료를 상승하는 피스톤의 압축력에 의해 폭팔 연소되어 발생되는 고온(600℃∼1,000℃ 이상)의 연소가스이다.The exhaust gas of the combustion chamber is a combustion gas of high temperature (600 ° C. to 1,000 ° C. or more) generated by explosive combustion by an electric spark and a compression force of a piston that raises the inhaled fuel according to the type of engine gasoline engine or diesel engine.
상기와 같은 고온의 연소가스 즉 배기가스는 첨부된 예시도면 도 2 에 표현된 바와같이, 실린더헤드(3)의 배출구(7)를 통해 배기매니폴드(1)로 배출이 된다.As described above, the high temperature combustion gas, that is, the exhaust gas, is discharged to the exhaust manifold 1 through the outlet 7 of the cylinder head 3, as represented in FIG. 2.
상기 배기매니폴드(1)는 그 형상이 연소실로 부터 배출되는 배기가스를 중앙이나 어느 한쪽으로 모을 수 있도록 배기구가 형성되어 있고, 배기가스의 유출저항이나 배기간섭이 작도록 형성되어 있다.The exhaust manifold 1 is formed so that the exhaust port is formed so that the exhaust gas discharged from the combustion chamber can be collected in the center or on either side, and the outflow resistance of the exhaust gas and the interference of the exhaust gas are small.
특히 차종에 따라 주철이나 강관으로 성형되고 외주면에 돌출된 결합부(8)를 형성시켜 실린더헤드(3)의 배출구(7)에 결합될 때 가스켓(9)을 삽입시키고 결합보울트(2)를 이용하여 기밀성이 유지된 상태로 결합이 된다.In particular, the gasket 9 is inserted into the outlet 7 of the cylinder head 3 by forming a coupling part 8 formed in cast iron or steel pipe and protruding on the outer circumferential surface, and using the coupling bolt 2 according to the vehicle type. The combination is maintained in the airtight state.
이때 외부로 배출되는 고온의 배기가스는 그 배출속도도 음속에 가까우며 대기중에 방출될 때 급격히 팽창하기 때문에 격렬한 폭음을 일으키게 되고, 이러한 폭음의 음압과 음파를 감소시키기 위해 소음기를 거쳐 외부로 배출이 된다.At this time, the high-temperature exhaust gas discharged to the outside is close to the speed of sound, and when it is released into the air, it expands rapidly, causing vigorous binge, and it is discharged through the silencer to reduce the sound pressure and sound wave of the binge. .
그러나, 상기와 같은 배기매니폴드(1)를 실린더헤드(3)의 배출구(7)측에 가스켓(9)을 삽입시킨 상태로 결합부(8)를 통해 결합보울트(2)로 실린더헤드(3)의 측면에 부착시키면, 연소실의 고온의 배기가스가 배기매니폴드(1)를 통해 배출이 되면서 결합부(8)를 가열시키게 되어 실린더헤드(3)와 배기매니폴드(1)의 재질상의 차이로 인해 열팽창 계수가 달라 결합보울트(2)의 체결길이의 변화와 축력변화에 의해 기밀성을 유지하는 가스켓(9)이 이격되어 배기가스가 유출되는 문제점이 있었다.However, the cylinder head 3 is connected to the coupling bolt 2 through the coupling portion 8 with the exhaust manifold 1 as described above inserted into the outlet 7 side of the cylinder head 3. 2), the hot exhaust gas of the combustion chamber is discharged through the exhaust manifold 1 to heat the coupling part 8, so that the material difference between the cylinder head 3 and the exhaust manifold 1 is different. Due to the different coefficient of thermal expansion, there is a problem in that the exhaust gas is leaked out by the gasket 9 to maintain the airtightness by the change in the fastening length and the change in the axial force of the coupling bolt (2).
이에 본 고안은 종래 자동차용 배기매니폴드가 지닌 문제점을 해소하기 위해 고안된 것으로, 실린더헤드에 부착되는 배기매니폴드의 외주면에 일정간격으로 형성된 결합부를 개선하여 배기매니폴드를 실린더헤드에 결합시켜 주는 축력변화를 감소시켜 배기가스의 유출을 방지할 수 있도록 한 자동차용 배기매니폴드를 제공하는데 목적이 있다.Therefore, the present invention is designed to solve the problems of the conventional automobile exhaust manifold, and the axial force that couples the exhaust manifold to the cylinder head by improving the coupling portion formed at regular intervals on the outer circumferential surface of the exhaust manifold attached to the cylinder head. It is an object of the present invention to provide an automobile exhaust manifold which can reduce the change to prevent the emission of exhaust gas.
상기와 같은 목적을 실현하기 위하여 본 고안은 배기매니폴드와 실린더헤드 사이에 가스켓을 삽입시켜 배기매니폴드의 외주면에 형성된 결합부를 통해 결합보울트로 부착이 되는 자동차의 배기매니폴드에 있어서, 상기 결합부는 외측리브와 내측리브가 형성되고 그 사이에 홈부를 형성시켜 삽입되는 결합보울트가 대기중에 노출되도록 함으로서, 실린더헤드에 결합되는 결합보울트의 체결길이의 변화와 축력변화를 억제시켜 가스켓의 기밀성을 유지하게 됨으로 배기가스의 유출을 방지하도록 된 것이다.In order to realize the above object, the present invention provides a vehicle exhaust manifold in which a gasket is inserted between an exhaust manifold and a cylinder head to be attached to a coupling bolt through a coupling portion formed on an outer circumferential surface of the exhaust manifold, wherein the coupling portion By forming the outer ribs and the inner ribs and forming grooves therebetween to expose the coupling bolts inserted into the atmosphere, thereby maintaining the airtightness of the gasket by suppressing the change in the coupling length and the axial force change of the coupling bolts coupled to the cylinder head. It is to prevent the leakage of exhaust gas.
