Description
일반적으로 자동차는 휘발유,경유 및 윤활유가 혼합된 혼합유 등의 각종 연료를 에너지원으로 사용하는데,상기 연료를 엔진의 실린더내로 유입시켜 점화플러그에 의해 점화시켜서 크랭크축을 회전시키는 흡입,압축,팽창,배기행정을 통해 상기 크랭크축의 플라이휠을 회전시키므로써 동력을 바퀴에 전달하게 된다.In general, automobiles use various fuels, such as gasoline, diesel, and mixed oils mixed with lubricating oil, as energy sources.Intake, compression, expansion, Power is transmitted to the wheels by rotating the flywheel of the crankshaft through the exhaust stroke.
상기한 자동차의 엔진은 다실린더 엔진으로서,각 실린더가 흡입, 압축,팽창,배기의 한 사이클을 피스톤의 4행정,즉 크랭크축 2회전으로 1회의 폭발을 갖는 엔진이다.The engine of the motor vehicle is a multicylinder engine, in which each cylinder has one explosion of intake, compression, expansion, and exhaust in one stroke of four strokes of the piston, that is, two revolutions of the crankshaft.
이렇게 각 실린더가 점화연소되는데,각 실린더의 동력행정인 팽창행정을 위한 점화연소 순서는 4실린더 엔진을 예를들면,제 1실린더가 상사점에 있을때는 제 4실린더도 마찬가지로 상사점에 있고,제 2,3실린더는 하사점에 있어 제 1 → 제 3 → 제 4 → 제 2실린더의 순서로 된다.In this way, each cylinder is ignition-burned, and the ignition combustion sequence for the expansion stroke, the power stroke of each cylinder, is a four-cylinder engine, for example, when the first cylinder is at top dead center, the fourth cylinder is also at top dead center. The second and third cylinders are in the order of the first → third → fourth → second cylinder in the bottom dead center.
이와같이 각기 다른 순서로 점화연소된 실린더는 배기행정을 통해 고온고압의 배기가스를,실린더의 배기가스를 종합하는 배기다기관,배기가스내의 공해물질을 무해물질로 변화시키는 촉매컨버터,배기가스를 대기중으로 배출하는 배기파이프 및 배기소음을 저하시키는 소음기를 통해서 외부로 배출시킨다.The cylinders ignited and burned in a different order as described above have a high temperature and high pressure exhaust gas through the exhaust stroke, an exhaust manifold that integrates the exhaust gas of the cylinder, a catalytic converter which converts pollutants in the exhaust gas into harmless substances, and the exhaust gas into the atmosphere. The exhaust pipe is discharged to the outside through the exhaust pipe and the silencer that reduces the exhaust noise.
상기 촉매컨버터는 배기가스에 포함된 일산화탄소(CO),탄화수소(HC),질소산화물(NOX)과 같은 공해물질을 무해한 물(H2O),질소(N2)로 산화/환원시키는 역할을 한다.The catalytic converter serves to oxidize / reduce pollutants such as carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NO X ) contained in the exhaust gas into harmless water (H 2 O) and nitrogen (N 2 ). do.
상기와 같이 배출되는 배기가스는 유해한 공해물질이기 때문에 공해감소가 현재 자동차 기술에 있어서 중요한 문제이고,또한 각 나라마다 배기가스의 규제기준이 다르고 사용연료도 달라 수출을 하려면 해당지역 또는 해당국가의 해당연료에 따른 기준에 맞추어야 하므로 자동차 생산업체들은 배기가스 분석기를 사용하여 배기파이프로부터 나오는 일산화탄소,탄화수소,질소산화물등 공해물질을 측정하고 있다.As the above-mentioned exhaust gas is a harmful pollutant, pollution reduction is an important problem in the current automobile technology, and in order to export with different emission standards and different fuels in each country, it is necessary to To meet fuel standards, automakers use an exhaust analyzer to measure pollutants such as carbon monoxide, hydrocarbons, and nitrogen oxides from exhaust pipes.
실제 우리나라의 경우도 새로 개발된 차뿐만 아니라 수입차도 배기가스 검사를 통하여 규제기준에 통과하여야 국내에서 판매가 가능한 실정이다.In fact, in Korea, imported cars as well as newly developed cars must pass the regulatory standards through the exhaust gas inspection to be sold in Korea.
그런데 배기가스가 촉매컨버터를 거쳐 외부로 배출된다 하더라도 촉매컨버터의 정화율 한계로 인해 일산화탄소,탄화수소,질소산화물등의 공해물질을 낮추는데는 한계가 있어 배기가스로 인한 환경오염의 문제가 있었다.However, even though the exhaust gas is discharged to the outside through the catalytic converter, there is a limit in reducing pollutants such as carbon monoxide, hydrocarbons, and nitrogen oxides due to the purification rate limitation of the catalytic converter.
따라서 본 고안의 목적은 상기의 문제점을 해결하기 위한 것으로서 실린더내에서 배기포트,배기다기관 및 배기파이프를 통해 외부로 배출되는 배기가스의 공해물질을,배기가스를 재연소시켜 저감함으로써 환경오염을 최소화할 수 있도록 한 자동차의 배기가스 공해물질 저감장치를 제공함에 있다.Accordingly, an object of the present invention is to solve the above problems, and to minimize environmental pollution by reducing the pollutants of the exhaust gas discharged to the outside through the exhaust port, the exhaust manifold and the exhaust pipe in the cylinder by reburning the exhaust gas. The present invention provides a device for reducing exhaust emissions of automobiles.
이와같은 본 고안은 배기포트에 에어유통 파이프를 설치하고,상기 에어유통 파이프에 에어를 공급하는 에어컴프레서와 체크밸브를 설치함으로써 달성될수 있다.The present invention can be achieved by installing an air distribution pipe in the exhaust port and installing an air compressor and a check valve for supplying air to the air distribution pipe.
이러한 본 고안은 엔진 회전수에 따라 상기 체크밸브가 에어컴프레서에 의해 공급되는 에어량을 조절하여 배기포트로 보냄에 따라 상기 에어가 실린더에서 배출되는 배기가스와 재연소됨으로써 상기의 목적을 효과적으로 달성할수 있다.The present invention can effectively achieve the above object by regulating the amount of air supplied by the air compressor to the exhaust port according to the engine speed and re-combusing the air with the exhaust gas discharged from the cylinder. .

이하 본 고안의 목적을 효과적으로 달성할수 있는 바람직한 실시예로서 그 기술구성 및 작용효과를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings the technical configuration and effect as a preferred embodiment that can effectively achieve the object of the present invention as follows.
도1은 본 고안에 의한 배기가스 공해물질 저감장치의 기술구성도룰 나타낸 것으로서,이에 나타낸 바와같이 본 고안은 배기포트(5)에 에어유통 파이프(4)를 설치하고,상기 에어유통 파이프(4)에 에어를 공급하는 에어컴프레서(1)와 엔진 컨트롤유닛(E.C.U)(3)에 의해 엔진의 회전수에 따라 개도되어 상기 에어량을 조절하는 체크밸브(2)를 설치하여 구성한 것이다.Figure 1 shows the technical configuration of the exhaust gas pollutant reducing apparatus according to the present invention, as shown in the present invention is provided with an air distribution pipe (4) in the exhaust port (5), the air distribution pipe (4) The air compressor 1 and the engine control unit (ECU) 3 for supplying air to the air supply unit are provided in accordance with the rotational speed of the engine to provide a check valve 2 for adjusting the air amount.
즉,본 고안은 배기포트(5)에 연결되는 에어유통 파이프(4); 시동시 상기 에어유통 파이프(4)에 에어를 공급하는 에어컴프레서(1); 그리고 시동시 엔진 회전수에 따라 엔진 컨트롤유닛(E.C.U)(3)에 의해 제어되어 상기 에어량을 조절하는 체크밸브(2)로 구성된 것이다.That is, the present invention is an air distribution pipe (4) connected to the exhaust port (5); An air compressor (1) for supplying air to the air distribution pipe (4) at startup; And it is composed of a check valve (2) for controlling the air amount is controlled by the engine control unit (E.C.U) (3) in accordance with the engine speed at startup.
이와같은 본 고안에 의해 시동을 걸면 에어컴프레서(1)가 작동됨과 아울러 엔진 컨트롤유닛(3)에 의해 엔진회전수에 따라 체크밸브(2)가 제어되어,즉 체크밸브(2)의 개도정도가 제어되어 에어 유통파이프(4)를 통해 에어가 흐르게 된다.When the engine is started according to the present invention, the air compressor 1 is operated and the check valve 2 is controlled by the engine control unit 3 according to the engine speed, that is, the opening degree of the check valve 2 is increased. It is controlled so that the air flows through the air distribution pipe (4).
이렇게 에어 유통파이프(4)로 흐르는 에어는 배기포트(5)로 보내져 실린더(6)에서 배기밸브(7)의 개방에 의해 배기포트(5)로 배출되는 배기가스와 혼합되어 화학반응에 의해 재연소가 일어나는 것이다.The air flowing through the air distribution pipe 4 is sent to the exhaust port 5, mixed with the exhaust gas discharged from the cylinder 6 to the exhaust port 5 by opening the exhaust valve 7, and regenerated by a chemical reaction. The cow is rising.
통상 엔진 회전수가 높으면 배기가스의 공해물질이 낮아지고,엔진 회전수가 낮으면 배기가스 공해물질이 많아지는데,엔진 회전수가 높을 경우는 체크밸브(2)의 개도정도가 적어지고,엔진 회전수가 낮을 경우는 체크밸브(2)의 개도정도가 커져 공급되는 에어량을 조절함으로써 유효적절하게 공해물질을 최소화하게 되는 것이다.In general, when the engine speed is high, the pollutants in the exhaust gas are low, and when the engine speed is low, the exhaust gas pollutants are high.In the case where the engine speed is high, the degree of opening of the check valve 2 is small, The opening degree of the check valve 2 is increased to effectively control the amount of air supplied to minimize the pollutants effectively.
다시 말해서 엔진 회전수에 따라 공해물질을 최소화할 수 있는 최적의 에어를 공급하게 되는 것이다.In other words, according to the engine speed, it is to provide the optimum air to minimize the pollutants.
이상에서 상술한 바와같이 본 고안은 배기가스 공해물질 저감장치에 의해 에어를 배기포트에 보내어 배기가스와의 화학반응에 의한 재연소를 일으키도록 한 것으로,이러한 재연소에 의해 공해물질이 최소화되어 외부로 배출됨으로써 환경오염을 최소화할 수 있게 되는 것이다.As described above, the present invention sends air to the exhaust port by means of an exhaust gas pollutant reduction device to cause reburn by chemical reaction with the exhaust gas. The pollutant is minimized by the reburn. It is possible to minimize the environmental pollution by being discharged to.
본 고안은 자동차의 배기가스 공해물질 저감장치에 관한 것으로서 더욱 상세히는 엔진의 실린더내에서 배기파이프를 통해 외부로 배출되는 배기가스를 재연소시켜 배기가스의 공해물질을 저감함으로써 환경오염을 최소화할 수 있도록 한 자동차의 배기가스 공해물질 저감장치를 제공하기 위한 것이다.The present invention relates to an apparatus for reducing exhaust gas pollutants in automobiles, and more particularly, to reduce environmental pollution by reducing the pollutants in exhaust gases by re-burning exhaust gases discharged to the outside through exhaust pipes in an engine cylinder. In order to provide an exhaust gas pollution reduction device for a vehicle.
