본 고안은 자동차의 배기장치에 관한 것으로서, 특히, 자동차의 초기시동시 배출되는 별도의 부배기관상에 배기가스 가열수단을 설치하여 배기가스를 일정 온도 이상으로 상승시킨 후 촉매 컨버터에 보냄으로써 배기가스의 촉매 정화효율을 향상시킨 자동차의 초기시동시 배기장치에 관한 것이다.The present invention relates to a vehicle exhaust system, in particular, by installing the exhaust gas heating means on a separate exhaust pipe discharged during the initial start-up of the vehicle to raise the exhaust gas to a predetermined temperature or higher and send it to the catalytic converter The present invention relates to an exhaust system for the initial start-up of a vehicle which improves the catalytic purification efficiency of the vehicle.
일반적으로 자동차의 배기장치는 제 1 도에 도시된 바와 같이 각 실린더에서 배출되는 배기가스를 종합하는 배기 매니폴드(10)와, 상기 배기 매니폴드(10)에 연결되어 배기가스를 대기 중으로 배출하는 배기관(20)과, 상기 배기 매니폴드(10) 또는 배기관(20) 상에 설치되어 배기 가스 유해성분을 산화, 환원시키는 촉매 컨버터(30)와, 상기 배기관(20)의 뒷부분에 설치되어 배기 소음을 저하시키는 머플러(40)등으로 구성된다.In general, as shown in FIG. 1, an exhaust device of an automobile is connected to an exhaust manifold 10 that aggregates exhaust gas emitted from each cylinder, and connected to the exhaust manifold 10 to exhaust the exhaust gas into the atmosphere. The exhaust pipe 20, the catalytic converter 30 installed on the exhaust manifold 10 or the exhaust pipe 20 for oxidizing and reducing harmful components of the exhaust gas, and the exhaust noise provided at the rear of the exhaust pipe 20 It is comprised by the muffler 40 etc. which reduce this.
상기와 같이 구성된 종래 자동차의 배기장치에서 특히, 상기 촉매 컨버터(30)는 상기 배기관(20) 도중 또는 상기 배기 매니폴드(10)에 설치되는 것으로서, 상기 촉매 컨버터(30) 속을 배기가스가 통과하면 배기가스 중의 유해한 일산화탄소(CO), 탄화수소(HC), 질소산화물(NOx)을 무해한 수증기(H2O), 질소(N2), 탄산가스(CO2)로 산화, 환원시킨다.In the exhaust apparatus of the conventional vehicle configured as described above, in particular, the catalytic converter 30 is installed in the exhaust pipe 20 or the exhaust manifold 10, and exhaust gas passes through the catalytic converter 30. The harmful carbon monoxide (CO), hydrocarbons (HC) and nitrogen oxides (NOx) in the exhaust gas are oxidized and reduced with harmless water vapor (H 2 O), nitrogen (N 2 ) and carbon dioxide (CO 2 ).
그러나, 상기 촉매 컨버터(30) 내의 촉매 작용은 통과하는 배기가스가 일정 온도 이상이 되어야만 제기능을 발휘하고, 일정 온도 이하에서는 정화 효율이 떨어지게 된다. 즉, 자동차 엔진을 초기 작동하여 워밍업을 하게 되면 처음에는 엔진 각 부분의 온도가 낮은 상태에서 작동하게 된다. 특히, 각 실린더에서 배출되는 배기가스의 온도도 실린더 헤드와 배기 매니폴드(10), 그리고 배기관(20)을 통과하는 과정에서 온도가 더 낮아지게 된다.However, the catalytic action in the catalytic converter 30 is only effective when the exhaust gas passing through the predetermined temperature or more, and the purification efficiency is lowered below the predetermined temperature. In other words, when the engine is warmed up by the initial operation of the automobile engine, the engine is initially operated at a low temperature of each part of the engine. In particular, the temperature of the exhaust gas discharged from each cylinder also becomes lower in the process of passing through the cylinder head, the exhaust manifold 10, and the exhaust pipe 20.
또한, 상기 촉매 컨버터(30)가 배출되는 배기가스에 의해 충분히 예열되지 못했기 때문에 촉매 컨버터(30) 내에서 촉매 물질이 충분히 활성화되지 못하게 된다.In addition, since the catalytic converter 30 is not sufficiently preheated by the exhaust gas discharged, the catalytic material is not sufficiently activated in the catalytic converter 30.
그래서, 상기와 같이 종래의 배기장치는 자동차의 초기시동시 배출되는 배기가스가 촉매 컨버터(30)에서 충분하게 산화, 환원되지 않기 때문에 촉매 컨버터(30)의 정화 효율이 낮아 유해 가스의 상당량이 외부로 배출되는 문제점이 있다.Therefore, as described above, since the exhaust gas discharged at the initial start-up of the vehicle is not sufficiently oxidized and reduced in the catalytic converter 30 as described above, the catalytic converter 30 has low purification efficiency and a significant amount of harmful gas is There is a problem that is discharged.
따라서, 본 고안은 상기와 같은 종래 기술의 문제점을 해결하기 위하여 안출된 것으로서, 본 고안의 목적은, 초기시동시 배출되는 별도의 주배기관에 가열수단을 설치하여 초기시동시 배기가스의 온도를 상승시킴으로써 배기가스 정화 효율이 향상되도록 한 초기시동시 배기 장치를 제공하는 데 있다.Accordingly, the present invention has been made to solve the problems of the prior art as described above, the object of the present invention is to install a heating means in a separate main exhaust pipe discharged during the initial startup to increase the temperature of the exhaust gas during the initial startup In order to improve the exhaust gas purification efficiency, the present invention provides an exhaust device during initial startup.

An exhaust device of a vehicle, comprising: a sub exhaust pipe branched from the exhaust manifold and connected to the main exhaust pipe, a three-way valve provided on the exhaust manifold to open and close the main exhaust pipe and the sub exhaust pipe; And a heating means connected to the exhaust gas collecting tube installed in the exhaust gas collecting tube, the heating means for heating the exhaust gas to the catalytic converter, and the ECU controlling the three-way valve by controlling the heating temperature of the exhaust gas by the heating means. It features.
이하, 첨부된 도면을 참조하여 본 고안에 의한 자동차의 초기시동시 배기장치의 실시예 를 상세하게 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings will be described in detail an embodiment of the exhaust system during the initial startup of the vehicle according to the present invention.
본 고안에 의한 자동차 초기시동시 배기장치는 제 2 도에 도시된 바와 같이 배기 매니폴드(50) 상에 삼방밸브(60)가 설치되고, 상기 삼방 밸브(60)에서 분리되는 별도의 부배기관(70) 상에 배기가스 포집통(80)과 가열수단(90)가 설치되어 촉매 컨버터(55)에 연결되어 있다.Exhaust device at the time of initial start-up of the vehicle according to the present invention is a three-way valve 60 is installed on the exhaust manifold 50, as shown in Figure 2, a separate auxiliary pipe (separated from the three-way valve 60) An exhaust gas collecting vessel 80 and a heating means 90 are installed on the catalyst 70 and connected to the catalytic converter 55.
본 고안은 배기 매니폴드(50)에서 주배기관(53)과 별도로 연결되어 촉매컨버터(55)을 이어지는 부배기관(70)과, 상기 부배기관(70)과 주배기관(53)을 ECU(100)의 제어에 의해 개폐시키는 삼방밸브(60)와, 상기 부배기관(70) 상에 설치되어 배기가스를 포집하는 배기가스 포집통(80)과, 상기 배기가스 포집통(80)과 연결되고 배기가스를 가열하여 촉매컨버터(55)로 보내는 가열수단(90)과, 상기 가열수단(90)에 의한 배기가스의 가열온도를 조절하고 상기 삼방밸브(60)와 배기가스 포집통(80)을 제어하는 ECU(100)로 구성된다.The present invention is connected to the main exhaust pipe 53 in the exhaust manifold (50) to continue the catalytic converter 55, and the secondary exhaust pipe 70 and the main exhaust pipe 53 to the ECU (100) The three-way valve 60 to be opened and closed by the control of the exhaust gas, an exhaust gas collecting cylinder 80 installed on the secondary exhaust pipe 70 to collect the exhaust gas, and connected to the exhaust gas collecting cylinder 80 and exhaust gas. Heating means 90 to be heated to the catalytic converter 55 and to control the heating temperature of the exhaust gas by the heating means 90 and to control the three-way valve 60 and the exhaust gas collecting container 80. It consists of ECU100.
상기와 같이 구성된 본 고안에 의한 자동차 초기시동시 배기장치의 작용 및 효과는 다음과 같다.The operation and effects of the exhaust system during the initial start-up of the vehicle according to the present invention configured as described above are as follows.
자동차의 엔진이 작동하게 되면, 실린더내의 혼합가스가 폭발하여 연소후의 배기가스가 배출된다. 이 때 ECU(100)의 제어에 의해 삼방밸브(60)가 본관인 주배기관(53) 쪽은 닫고 가지관인 부배기관(70) 쪽을 개방하여 배출되는 배기가스가 부배기관(70)으로 배출된다.When the engine of a vehicle is operated, the mixed gas in a cylinder explodes and exhaust gas after combustion is exhausted. At this time, under the control of the ECU 100, the exhaust gas discharged by closing the main exhaust pipe 53 side of which the three-way valve 60 is the main pipe and opening the side of the main exhaust pipe 70 which is the branch pipe is discharged to the sub exhaust pipe 70. .
그리고 상기 부배기관(70)으로 배출되는 배기가스는 배기가스 포집통(80)에 포집되어 가열수단(90)로 보내진다. 이렇게 가열수단(90)에 인입된 배기가스는 ECU(100)의 제어에 의해 일정온도 이상으로 가열되어 본류인 촉매컨버터(55)로 보내진다.And the exhaust gas discharged to the secondary exhaust pipe 70 is collected in the exhaust gas collecting container 80 is sent to the heating means (90). The exhaust gas introduced into the heating means 90 is heated above a predetermined temperature by the control of the ECU 100 and is sent to the catalytic converter 55 which is a mainstream.
상기와 같이 가열수단(90)에서 일정온도 이상으로 가열된 배기가스는 촉매컨버터(55) 내에서 활발하게 산화, 환원되어 머플러(58)를 통해서 외부로 배출된다.Exhaust gas heated above a predetermined temperature in the heating means 90 as described above is actively oxidized and reduced in the catalytic converter 55 is discharged to the outside through the muffler (58).
상기와 같이 설치되고 작동되는 본 고안은 배기 매니폴드(50)에서 연결되는 별도의 부배기관(70) 상에 가열수단(90)가 설치되어, 엔진의 초기작동시 배출되는 배기가스의 온도를 일정 온도 이상으로 상승시켜 촉매컨버터(55)에 보내기 때문에 촉매 컨버터(55) 내의 산화, 환원작용이 원활하여 배기가스의 정화효율이 향상되는 잇점이 있다.In the present invention installed and operated as described above, the heating means 90 is installed on a separate sub-exhaust pipe 70 connected from the exhaust manifold 50, so that the temperature of the exhaust gas discharged during the initial operation of the engine is constant. Since it is raised above and sent to the catalytic converter 55, there is an advantage in that the oxidation and reduction in the catalytic converter 55 is smooth and the purification efficiency of the exhaust gas is improved.
