일반적으로, 승용 디젤엔진용 배기 매니폴드는 원가를 고려하여 회주철계열의 주물로 제작되어왔다. In general, exhaust manifolds for passenger diesel engines have been manufactured from gray cast iron series in consideration of cost.

상기 주물 배기 매니폴드는 배기가스의 보온성이 나쁘기 때문에 배기가스의 온도가 떨어져 터보챠저의 효율저하 및 낮은 배기가스의 온도로 인해 후처리 활성이 떨어지는 문제점이 있다.The casting exhaust manifold has a problem in that the post-treatment activity is inferior due to the decrease in the efficiency of the turbocharger and the low exhaust gas temperature because the exhaust gas temperature is poor because the heat retention of the exhaust gas is poor.

즉, 종래의 배기 매니폴드는 주물의 단품으로 제작되는 바, 각 실린더헤드와 연결된 런너를 통해 터보챠저로 유출되는 배기가스가 서로 간섭되어 유량계수가 저하되어 성능이 저하되는 문제점이 있다.That is, the conventional exhaust manifold is made of a single product of the casting, there is a problem that the exhaust gas flowing out to the turbocharger through the runner connected to each cylinder head interferes with each other, the flow coefficient is lowered and the performance is lowered.

본 발명은 각 런너를 통해 흐르는 배기가스의 간섭이 회피되어 유량계수가 높으며, 상기 배기가스의 온도저하를 방지하여 터보차져의 효율을 높일 수 있는 배기 매니폴드를 제공하는데 그 목적이 있다.An object of the present invention is to provide an exhaust manifold that can avoid the interference of the exhaust gas flowing through each runner to have a high flow coefficient, and to prevent the temperature of the exhaust gas from being lowered, thereby improving the efficiency of the turbocharger.

본 발명은 엔진의 실린더 배기포트와 일단이 각각 연결되는 제1런너 및 제2런너 및 제3런너와, 상기 제1런너 및 제2런너 각각의 타단과 일단이 결합되는 제1커넥터, 일단이 상기 제1커넥터의 타단 및 상기 제3런너의 타단과 결합되며 타단이 터보챠저와 연결되는 제2커넥터를 포함하는 배기 매니폴드를 제공한다.The present invention includes a first runner and a second runner and a third runner, one end of which is connected to a cylinder exhaust port of an engine, and a first connector of which one end is coupled to the other end of each of the first runner and the second runner.
