Description
본 고안은 자동차의 배기가스 가열장치에 관한 것으로, 더 상세히는 시동 초기에 배기가스를 가열시켜 촉매 컨버터를 정상적으로 작동시키고 배기가스를 원활히 배출시킬 수 있도록 한 자동차의 배기가스 가열장치에 관한 것이다.The present invention relates to an exhaust gas heating apparatus for a vehicle, and more particularly, to an exhaust gas heating apparatus for an automobile which enables the exhaust gas to be heated at the initial start-up to operate the catalytic converter normally and to smoothly discharge the exhaust gas.
엔진이 작동하기 위해서는 실린더 안에 혼합기를 흡입하고, 또 혼합기가 연소한 후 그 연소가스를 외부로 배출하게 되는데 이일을 하는 것이 흡개비 장치이다.In order to operate the engine, the mixer is sucked into the cylinder, and after the mixer is burned, the combustion gas is discharged to the outside.
배기장치는 각 실린더의 연소가스를 모으는 배기 매니폴드와 연소가스가 외부로 나가는 배기파이프, 촉매 컨버터 및 소음기로 구성되어 있다. 그리고 배기 매니폴드는 시동 초기에 엔진이 정상작동 온도에 도달할 때까지 흡기를 가열시켜 기화를 촉진시켜 주는 역할을 하기도 한다.The exhaust system is composed of an exhaust manifold that collects the combustion gas of each cylinder, and an exhaust pipe, a catalytic converter, and a silencer that exhaust the combustion gas to the outside. The exhaust manifold also serves to promote vaporization by heating the intake air until the engine reaches normal operating temperature at the start of the startup.
그런데, 시동 초기에는 배기 매니폴드의 온도가 낮아 촉매 컨버터가 정상작동 되지 않고 배기 파이프의 배기작용이 원활하지 못할 뿐더러 흡기를 빠르게 가열하지 목하여 기화를 촉진시키는 역할이 부족하였다.However, in the initial stage of start-up, the temperature of the exhaust manifold was low, so that the catalytic converter did not operate normally, the exhaust pipe was not smoothly ventilated, and the intake was not heated quickly.
따라서, 시동 초기에 배기가스를 빠르게 가열시켜 촉매 컨버터를 정상적으로 작동되게 하여 배기작용을 원활하게 하고 기화를 촉진시킬 필요성이 있다.Therefore, there is a need to quickly heat the exhaust gas at the start of the startup so that the catalytic converter operates normally to facilitate the exhaust action and promote vaporization.
이러한 점을 감안하여 본 고안은 시동 초기에 촉매 컨버터가 정상작동 온도에 도달할 때까지 배기가스를 가열시켜 줄 수 있는 자동차의 배기가스 가열장치를 제공하고자 한다.In view of this point, the present invention seeks to provide a vehicle exhaust gas heating device capable of heating the exhaust gas at the initial stage of startup until the catalytic converter reaches its normal operating temperature.
본 고안은 배기 매니폴드(10)와 촉매 컨버터(30) 사이에 있는 배기 파이프(20)에 연결하여 바이패스로를 형성시킨 보조 파이프(100)와, 상기 배기 파이프(20)와 보조 파이프(100)의 1차측 연결부위에 설치한 온도반응식 밸브(200)와, 상기 온도 반응식 밸브(200)의 개도시 배기가스를 히팅시킬 수 있도록 상기 보조 파이프(100)의 중간에 설치한 설치한 히터 유니트(300)로 구성된 것에 그 특징이 있다.The present invention is connected to the exhaust pipe 20 between the exhaust manifold 10 and the catalytic converter 30 to form an auxiliary pipe 100, the exhaust pipe 20 and the auxiliary pipe 100 A heater unit installed in the middle of the auxiliary pipe 100 to heat the temperature-reactive valve 200 installed at the primary side connection part of the heat sink and the exhaust gas of the open-air shown in the temperature-reactive valve 200 It is characterized by consisting of 300).

이하, 본 고안의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.
도 1은 본 고안에 따른 자동차의 배기가스 가열장치 구성도이다.1 is a configuration diagram of an exhaust gas heating apparatus of a vehicle according to the present invention.
도1에 도시한 바와같이, 보조 파이프(100)는 배기 파이프(20)와 동일한 직경으로 바이패스로가 형성되도록 배기 매니폴드(10)와 촉매 컨버터(30) 사이에 있는 배기 파이프(20)에 양단을 연결한다.As shown in FIG. 1, the auxiliary pipe 100 is connected to the exhaust pipe 20 between the exhaust manifold 10 and the catalytic converter 30 so that a bypass path is formed with the same diameter as the exhaust pipe 20. Connect both ends.
온도 반응식 밸브(200)는 배기가스의 온도가 설정온도 이하일 때 개도되고 일정온도 이상이 되면 폐쇄되는 것을 사용하여 보조 파이프(100)의 1차측 연결부위에 설치한다.The temperature-reactive valve 200 is opened when the temperature of the exhaust gas is lower than or equal to the set temperature, and is installed at the primary side connection portion of the auxiliary pipe 100 by using the closed one when the temperature exceeds the predetermined temperature.
히터 유니트(300)는 그 내부에 예열선(310)을 장치항 배기가스의 통과시 배기가스를 히팅시킬 수 있도록 한다. 이 예열선(310)(100)은 텅스텐을 사용하여 히터 유티트(300)의 내부에 권회시키고 온도 반응식 밸브(200)의 개도시에 도시하지 않은 배터리 전원을 공급받아 발열작용을 할 수 있도록 한다.The heater unit 300 allows the preheating line 310 to heat the exhaust gas when the apparatus port exhaust gas passes therein. The preheating lines 310 and 100 are wound around the inside of the heater unit 300 using tungsten and supplied with battery power not shown in the opening of the temperature-reactive valve 200 to generate heat. .
이러한 구성으로 된 본 고안은 차량을 운행하기 위하여 시동 스위치를 킨후, 초기에는 배기가스온도가 낮으므로 온도반응식 밸브(200)가 개도된다. 이때 보조 파이프(100)는 열리고 배기 파이프(20)는 닫히게 되어 배기가스가 보조파이프를 지니게 되고, 이와 동시에 히터 유니트(300)의 예열선(310)이 발열되어 있으므로 통과되는 배기가스는 가열된다. 가열된 배기가스는 촉매 컨버터(30)를 지나면서 정화가 잘 이루어진다. 시험결과 초기 발생되는 배기가스의 정화효율이 종전보다 50% 향상되었다.According to the present invention having such a configuration, after the start switch is turned on to operate the vehicle, the temperature-reactive valve 200 may be opened since the exhaust gas temperature is initially low. At this time, the auxiliary pipe 100 is opened and the exhaust pipe 20 is closed so that the exhaust gas has the auxiliary pipe, and at the same time, since the preheating line 310 of the heater unit 300 is heated, the exhaust gas passing through is heated. The heated exhaust gas passes through the catalytic converter 30 and is purified well. As a result of the test, the purification efficiency of the generated exhaust gas is improved by 50%.
이후, 배기가스의 온도가 일정온도 이상으로 상승되면, 온도반응식 밸브(200)가 열리게 되며, 이때 보조 파이프(100)는 닫히고 배기 파이프는 열리게 되므로, 배기 파이프(20)는 평상시와 같이 배기파이프와 촉매컨버터(30)를 통하여 배출된다.Then, when the temperature of the exhaust gas is raised above a certain temperature, the temperature-responsive valve 200 is opened, at which time the auxiliary pipe 100 is closed and the exhaust pipe is opened, so that the exhaust pipe 20 and the exhaust pipe as usual It is discharged through the catalytic converter (30).
상술한 바와 같이, 본 고안은 시동 초기에 배기가스를 가열시켜 촉매 컨버터(30)를 정상적으로 작동시키고 배기가스를 원활히 배출시키므로 엔진의 워밍업시간을 단축시켜 주고 배기가스의 정화효율이 향상되어 대기오염을 줄여주는 효과가 있다.As described above, the present invention heats the exhaust gas at the initial stage of operation so that the catalytic converter 30 operates normally and the exhaust gas is smoothly discharged, thereby shortening the engine warm-up time and improving the purification efficiency of the exhaust gas, thereby reducing air pollution. It has the effect of reducing it.
