The air duct 5 is formed, and the exhaust pipe 4 is cooled by the outside air flowing through the air duct 5 so as to improve the cooling efficiency.
Description
본 고안은 자동차용 배기다기관의 냉각구조에 관한 것으로, 특히 엔진의 소형화 추세에 따라 짧게 형성된 각 배기관이 합치되는 배기다기관부의 냉각효율을 향상시킬 수 있도록 된 자동차용 배기다기관의 냉각구조에 관한 것이다.The present invention relates to a cooling structure of an automobile exhaust manifold, and more particularly, to a cooling structure of an automobile exhaust manifold, which is capable of improving the cooling efficiency of the exhaust manifold unit in which each exhaust pipe formed shortly according to the miniaturization trend of the engine is matched.
일반적으로, 자동차 엔진의 연소실내에서 연소된 배기가스는 다수 구비된 각 연소실과 연통된 각각의 배기관을 따라 유동됨과 더불어, 상기 각 배기관이 단일관으로 합치되도록 된 배기다기관을 통해 촉매컨버터나 소음기 등을 통해 외부로 배출되도록 된다.In general, exhaust gas combusted in a combustion chamber of an automobile engine flows along each exhaust pipe communicating with each combustion chamber provided with a plurality of combustion engines, and a catalytic converter, a silencer, etc. is provided through an exhaust manifold in which each exhaust pipe is integrated into a single pipe. It is discharged to the outside through.
여기서, 상기 배기다기관은 엔진의 실린더헤드내에 구비되면서 각 연소실과 연통된 각 배기관과 접합·연통된 각각의 배기관이 일지점으로 뻗어 단일관과 연통되는 형상을 이루도록 되되, 근래 엔진의 소형화 추세에 따라 상기 각각의 배기관이 단일관과 합치되도록 뻗어지는 길이가 축소되어 형성되는 것이 보편화 되어 있다.Here, the exhaust manifold is provided in the cylinder head of the engine and each exhaust pipe connected to and connected to each exhaust pipe communicating with each combustion chamber extends to one point to form a shape in communication with a single pipe. It is common that each of the exhaust pipe is formed to be reduced in length extending to match the single pipe.
또, 상기 배기다기관은 종래에 도 3에 도시된 바와 같이, 다수의 배기관(4)이 단일관으로 합치되도록 주물 등의 공정을 통해 형성되도록 되어 상기 엔진의 실린더 헤드방향에 위치되어 각각 소정간격 이격되어 있는 각 배기관(4) 사이에 주형 등에 따라 배기다기관(2)의 몸체(3)가 이어져 접합된 이음부(6)가 형성된다.In addition, the exhaust manifold is conventionally, as shown in Figure 3, a plurality of exhaust pipes (4) are formed through a process such as casting so as to be matched in a single pipe is located in the cylinder head of the engine spaced apart by a predetermined interval, respectively Between the respective exhaust pipes 4, the body 3 of the exhaust manifold 2 is connected by a mold or the like to form a joint 6 that is joined.
그러나 상기와 같이, 각 배기관(4) 사이에 이음부(6)가 형성됨에 따라 외기 등이 배기다기관(2)의 몸체(3) 외측면을 따라 유동되면서 배기다기관(2)에서 발생되는 열을 빼앗아 상기 배기다기관(2)을 냉각시키도록 되어 엔진소형화에 따라 방열면적이 축소된 상태에서 상기와 같이 몸체(3) 외측에서의 방열만으로 배기다기관(2)이 냉각되도록 됨에 따라 상기 배기다기관(2)이 과열되거나 고온의 배기가스가 촉매컨버터 등으로 전해져 정화효율이 저하되는 문제가 발생되었다.However, as described above, as the joints 6 are formed between the exhaust pipes 4, the outside air flows along the outer surface of the body 3 of the exhaust manifold 2, and thus heat generated from the exhaust manifold 2 is collected. The exhaust manifold 2 is cooled to cool the exhaust manifold 2, so that the exhaust manifold 2 is cooled only by heat dissipation from the outside of the body 3 as described above in the state where the heat dissipation area is reduced according to the engine miniaturization. ) Overheating or high temperature exhaust gas is transferred to the catalytic converter, etc., resulting in a decrease in purification efficiency.
이에 본 고안은 상기와 같은 제반 문제점을 해소하기 위해 안출된 것으로, 주물제작에 따라 각 배기관 사이에 형성되는 이음부 등이 제거되어 이 이음부가 위치된 공간으로 외부공기 등이 유동되면서 상기 배기다기관이 냉각되도록 되어 냉각 효율을 향상시킬 수 있도록 된 자동차용 배기다기관의 냉각구조를 제공함에 그 목적이 있다.The present invention has been devised to solve the above problems, the joints formed between the exhaust pipes are removed according to the casting production, and the exhaust manifolds are moved while the outside air flows to the space where the joints are located. It is an object of the present invention to provide a cooling structure of an exhaust manifold for an automobile that is cooled to improve cooling efficiency.
