Description

배기 매니폴드와 실린더 헤드가 일체로 형성된 엔진{ENGINE THAT EXHAUST MANIFOLD AND CYLINDER HEAD ARE INTEGRALLY FOMRED}(ENGINE THAT EXHAUST MANIFOLD AND CYLINDER HEAD ARE INTEGRALLY FOMED)

본 발명은 엔진의 배기 시스템에 관한 것으로서, 더욱 상세하게는, 배기 매니폴더와 실린더헤드가 일체로 형성된 배기 시스템에 관한 것이다.The present invention relates to an exhaust system of an engine, and more particularly, to an exhaust system in which an exhaust manifold and a cylinder head are integrally formed.

통상적인 차량용 엔진은 내연기관(internal combustion engine)으로서, 실린더 내에서 연소된 배기가스의 배출을 위한 배기 시스템을 갖추고 있다. A typical vehicle engine is an internal combustion engine, equipped with an exhaust system for exhausting exhausted combustion gases in cylinders.

실린더의 배기가스가 실린더 헤드를 통해 배출되도록, 실린더 헤드 내에는 배기 포트가 형성되어 있다. 배기 포트로부터 배출되는 배기가스는 배기 매니폴드(exhaust manifold)를 통해 촉매 컨버터(catalytic converter)에 공급된다. An exhaust port is formed in the cylinder head so that the exhaust gas of the cylinder is discharged through the cylinder head. The exhaust gas discharged from the exhaust port is supplied to a catalytic converter through an exhaust manifold.

배기 매니폴드는 엔진과는 별도의 부품으로 제작되어 실린더 헤드에 볼트 등으로 결합된다. The exhaust manifold is manufactured as a separate component from the engine and is bolted to the cylinder head.

배기 매니폴드는 외부에 노출되어 있고 엔진과는 별도의 부재로 형성되므로, 워터 재킷 등으로 냉각시키지 못하고, 단지 공기의 흐름을 통해 냉각시키고 있다. Since the exhaust manifold is exposed to the outside and is formed of a member separate from the engine, the exhaust manifold can not be cooled by a water jacket or the like, but is cooled only through the flow of air.

실린더로부터 촉매 컨버터에 이르기까지 배기가스가 배출되기 위한 배기 시스템을 기구적으로 컴팩트하게 형성할 수 있다면, 엔진룸 공간을 효율적으로 활용 할 수 있게 된다. If the exhaust system for discharging the exhaust gas from the cylinder to the catalytic converter can be formed mechanically and compactly, the engine room space can be efficiently utilized.

또한, 촉매 컨버터에 이르기까지 배기가스의 온도를 적절하게 유지하면서도 내구성을 향상할 수 있는 배기 시스템이 개발되고 있다.Further, an exhaust system capable of improving the durability while maintaining the temperature of the exhaust gas appropriately up to the catalytic converter has been developed.

한편, 실린더의 배기포트에서 배출되는 배기가스의 냉각효과가 낮아 연비가 떨어지는 문제점이 있으며, 배기 매니폴드를 엔진에 별도로 장착함으로써 원가가 상승하고 엔진 구조가 복잡해지는 번거로움이 있었다. 뿐만 아니라 배기 가스에 의해서 배기 매니폴드에서 소음이 발생하여 운전감을 떨어드렸다.On the other hand, there is a problem that the cooling efficiency of the exhaust gas discharged from the exhaust port of the cylinder is low and the fuel efficiency is lowered, and the exhaust gas manifold is separately mounted in the engine, so that the cost increases and the engine structure becomes complicated. In addition, noise was generated in the exhaust manifold by the exhaust gas and the driving feeling was reduced.

본 발명은 배기가스의 온도가 적절하게 컨트롤되는 배기 매니폴드와 실린더 헤드가 일체로 형성된 엔진을 제공한다.The present invention provides an engine in which an exhaust manifold and a cylinder head in which the temperature of the exhaust gas is appropriately controlled are integrally formed.

아울러, 본 실시예에 따른 배기 매니폴드와 실린더 헤드가 일체로 형성된 엔진은, 두 개의 제1,2배기포트를 구비한 제1실린더 및 상기 제1실린더와 인접하고 두 개의 제3,4배기포트를 구비한 제2실린더를 포함하고, 내부에 상기 제1,2배기포트와 통하는 제1통로가 형성되고, 내부에 상기 제3배기포트와 통하는 제2통로가 형성되며, 상기 제1통로와 상기 제2통로가 합쳐져 제1싱글배기구로 통한다.In addition, the engine in which the exhaust manifold and the cylinder head according to the present embodiment are formed integrally has a first cylinder having two first and second exhaust ports, and a second cylinder adjacent to the first cylinder, A first passage communicating with the first and second exhaust ports is formed therein, a second passage communicating with the third exhaust port is formed therein, and the first passage and the second passage are communicated with each other, And the second passages are joined to the first single exhaust port.

아울러, 본 실시예에 따른 배기 매니폴드와 실린더 헤드가 일체로 형성된 엔진은, 두 개의 제1,2배기포트를 구비한 제1실린더, 상기 제1실린더와 인접하고 두 개의 제3,4배기포트를 구비한 제2실린더 및 상기 제2실린더와 인접하고 두 개의 제5,6배기포트를 구비한 제3실린더를 포함하고, 내부에 상기 제1,2배기포트와 통하는 제1통로가 형성되고, 내부에 상기 제3,4배기포트와 통하는 제2통로가 형성되며, 상 기 제5배기통로와 통하는 제3배기통로가 형성되며, 상기 제1통로는 제1싱글배기구와 연결되고, 상기 제2통로와 상기 제3통로가 합쳐져 제2싱글배기구로 통한다.In addition, the engine in which the exhaust manifold and the cylinder head according to the present embodiment are formed integrally includes a first cylinder having two first and second exhaust ports, a second cylinder adjacent to the first cylinder, And a third cylinder adjacent to the second cylinder and having two fifth and sixth exhaust ports, a first passage communicating with the first and second exhaust ports is formed in the third cylinder, And a third exhaust passage communicating with the fifth exhaust passage, wherein the first passage is connected to the first single exhaust port, the second exhaust passage communicated with the second exhaust passage, The passage and the third passage join together to pass through the second single outlet.

이상 설명한 바와 같이 본 발명의 실시예에 따른 배기 매니폴드와 실린더 헤드가 일체로 형성된 엔진에 의하면, 배기가스의 온도가 적절하게 컨트롤됨으로써 연비가 상승한다.As described above, according to the engine in which the exhaust manifold and the cylinder head are integrally formed according to the embodiment of the present invention, the fuel consumption is raised by appropriately controlling the temperature of the exhaust gas.

아울러, 배기 집합부에 가깝게 정화장치가 체결됨으로써 정화장치의 효율을 향상시킬 수 있으며, 배기구의 개수를 줄임으로써 컴팩트한 엔진의 설계가 가능하다.In addition, the efficiency of the purifier can be improved by tightening the purifier close to the exhaust assembly, and a compact engine can be designed by reducing the number of exhaust holes.

아울러, 배기 매니폴드가 실린더헤드에 일체로 형성됨으로써 원가가 절감되고, 내구성이 향상된다.In addition, since the exhaust manifold is integrally formed in the cylinder head, the cost is reduced and the durability is improved.

본 실시예에 따라서, 실린더헤드에 배기 매니폴드가 일체로 형성됨으로써 원가가 절감되고, 내구성이 증진된다. According to this embodiment, the exhaust manifold is integrally formed in the cylinder head, thereby reducing the cost and improving the durability.

또한, 실린더헤드가 연장된 끝부분에 배기집합부가 형성되고, 그 통로 중간에 워터자켓이 설치됨으로써 배기온도가 용이하게 컨트롤된다. 따라서, 연료의 희박화가 가능하여 연비가 향상된다.Further, an exhaust gas collecting portion is formed at an end portion where the cylinder head extends, and a water jacket is provided in the middle of the passage, so that the exhaust temperature is easily controlled. Therefore, the fuel can be made lean and the fuel consumption is improved.

또한, 촉매를 구비한 정화장치를 엔진에 가깝게 배치함으로써 LOT가 단축되는 장점도 있다.In addition, there is also an advantage that the LOT is shortened by arranging the purifier equipped with the catalyst close to the engine.
