Description
본 고안은 자동차의 배기계통 2차 공기 공급장치에 관한 것으로서, 보다 상세하게는 배기가스의 대책 일환으로 배기다기관에 공기를 공급하여 배기가스 속의 유해물질을 감소시키기 위한 자동차의 배기계통 2차 공기 공급장치에 관한 것이다.The present invention relates to a secondary system for supplying the exhaust system of an automobile, and more particularly, to supply the secondary system of the exhaust system for supplying air to the exhaust manifold as a countermeasure of the exhaust gas to reduce harmful substances in the exhaust gas. Relates to a device.
배기가스는 연료가 실린더 내에서 연소된 후 대기중으로 배출되는 가스로 유해한 가스인 일산화탄소, 탄화수소, 질소산화물, 납산화물, 탄소입자와 무해성 가스인 수증기, 이산화탄소가 혼합되어 배출된다. 따라서 인체에 해로운 유해 가스를 무해가스로 정화시켜 배출하도록 의무화하고 있기에 다음과 같은 방법을 사용하여 배기가스에 함유된 유해가스를 제거하려고 노력하고 있다Exhaust gas is a gas discharged into the atmosphere after fuel is combusted in a cylinder. The exhaust gas is a mixture of harmful gases such as carbon monoxide, hydrocarbons, nitrogen oxides, lead oxides, carbon particles, water vapor and carbon dioxide, which are harmless gases. Therefore, it is mandatory to purify and discharge harmful gas harmful to human body by harmless gas, so we are trying to remove harmful gas contained in exhaust gas by using the following method.
배기가스 속의 일산화탄소나, 탄화수소의 배출농도는 주로 혼합기의 혼합비에 따라 좌우되고, 질소산화물의 배출농도는 주로 연소 온도에 따라 좌우된다. 따라서, 연소실을 비롯하여 연료, 점화, 흡배기 계통을 종합적으로 개량하거나 연소 상태를 제어하는 부가장치를 설치하는 방식인 기관 개량방식과, 희박한 혼합기를 효율적으로 연소시키기 위해 일부 짙은 혼합기를 동시에 흡입시키는 방식인 성층급기 연소방식과, 기관의 각 부분을 개량함과 동시에 실린더에서 배출된 직후의 배기가스를 단열재로 감싼 더어밀 리액터에 유도하여 고온 상태를 유지하면서 공기를 넣어 일산화탄소와 탄화수소를 재연소시키는 방식인 더어멀 리액터(Thermal Reactor)방식과, 기관의 각 부분을 개량함과 동시에 유해가스를 산화 또는 환원촉매로 제거하는 방식인 촉매 컨버터방식이 있다.The emission concentration of carbon monoxide and hydrocarbons in the exhaust gas mainly depends on the mixing ratio of the mixer, and the emission concentration of nitrogen oxide mainly depends on the combustion temperature. Therefore, the engine improvement method, which is a method of comprehensively improving the combustion chamber, fuel, ignition, and intake / exhaust systems, or installing an additional device to control the combustion state, and a method of simultaneously inhaling some dense mixers to efficiently burn the lean mixture, In addition to improving the stratified air supply method and each part of the engine, the exhaust gas immediately after being discharged from the cylinder is introduced to a dust mill reactor wrapped with heat insulator, and the air is kept in a high temperature to reburn carbon monoxide and hydrocarbons. There is a thermal reactor method and a catalytic converter method that improves each part of the engine and removes harmful gases with an oxidation or reduction catalyst.
상기 기관 개량방식중 배기계통을 개량하여 배기가스를 줄이는 장치로는 2차 공기 공급장치와, 배기다기관 보온장치가 있다.The apparatus for reducing the exhaust gas by improving the exhaust system of the engine improvement system includes a secondary air supply device and an exhaust manifold thermostat.
상기 2차 공기라함은 엔진에 혼합기로서 흡입되는 공기를 1차 공기로 생각할때 상대적으로 배기계통에 공급되는 공기를 2차 공기로 하는 것이다.The secondary air refers to the air supplied to the exhaust system as the secondary air when considering the air sucked as a mixer in the engine as the primary air.
도1에는 기관 개량방식중 배기계통을 개량하여 배기가스를 줄이는 2차공기 공급장치를 나타낸 블록구성도를 도시하였다. 도1에 도시된 바와 같이 공기를 저장하는 서지탱크(10)와, 서지탱크(10)의 부압에 의해 개폐되는 콤비네이션밸브(40)와, 서지탱크(10)와 콤비네이션밸브(40)을 서로 연결하며 전기적으로 개폐되는 솔레노이드밸브(30)와, 솔레노이드밸브(30)를 개폐제어하는 ECU(20)와, 콤비네이션밸브(40)의 아웃포트(412)에 연결된 배기다기관(70)과, 공기를 정화하는 에어크리너(50)와, 에어크리너(50)의 공기를 콤비네이션밸브(40)의 인포트(410)로 공급하기 위한 공기펌프(60)로 이루어진다.Figure 1 shows a block diagram showing a secondary air supply device for reducing the exhaust gas by improving the exhaust system of the engine improvement method. As shown in FIG. 1, the surge tank 10 for storing air, the combination valve 40 opened and closed by the negative pressure of the surge tank 10, and the surge tank 10 and the combination valve 40 are connected to each other. And the solenoid valve 30 electrically opened and closed, the ECU 20 for opening and closing the solenoid valve 30, the exhaust manifold 70 connected to the outlet 412 of the combination valve 40, and purifies the air. The air cleaner 50 and the air pump 60 for supplying the air of the air cleaner 50 to the inlet 410 of the combination valve 40.
도2는 상기의 콤비네이션밸브(40)를 나타낸 부분 단면도로써 부압이 부압제어포트(402)를 통해 걸리면 막(404)이 상승하여 스톱퍼를 상승시킨다. 그러면 포트(408)가 열려 공기의 흐름이 인포트(410)에서 아웃포트(412)로 흐르게 된다. 그리고 부압이 제거되면 스톱퍼가 하강하여 포트(408)를 막게 됨으로 공기의 흐름이 차단된다.2 is a partial cross-sectional view of the combination valve 40 described above. When the negative pressure is applied through the negative pressure control port 402, the membrane 404 is raised to raise the stopper. The port 408 is then opened so that a flow of air flows from the inlet 410 to the outlet 412. When the negative pressure is removed, the stopper descends to block the port 408, thereby blocking the flow of air.
상기와 같이 이루어진 2차 공기 공급장치의 작동을 설명하면 다음과 같다. 시동초기에 ECU(20)에서 솔레노이드를 1분∼2분 가량 개방한다. 그러면 흡기행정시 발생되는 서지탱크(10)의 부압이 콤비네이션밸브(40)로 전달되어 콤비네이션밸브(40)가 개방된다. 그러면 이때 공기펌프(60)에 의해 에어크리너(50)에 의해 정화된 공기를 배기다기관(70)으로 공급하게 된다.Referring to the operation of the secondary air supply device made as described above are as follows. At the start of startup, the solenoid is opened in the ECU 20 for 1 to 2 minutes. Then, the negative pressure of the surge tank 10 generated at the intake stroke is transmitted to the combination valve 40 to open the combination valve 40. Then, the air purified by the air cleaner 50 by the air pump 60 is supplied to the exhaust manifold 70.
그런데 상기와 같이 콤비네이션밸브(40)가 서지탱크(10)에서 발생되는 부압에 의해 개폐되기 때문에 서지탱크(10)의 부압은 실린더의 각 행정에 따라 부압이 걸리기도 하고 걸리지 않기도 한다. 따라서 콤비네이션밸브(40) 또한 개폐를 반복하게 된다. 이렇게 작동됨으로써 배기다기관(70)에 공급되는 공기양은 일정하게 공급되지 않는다는 문제점이 있다.However, since the combination valve 40 is opened and closed by the negative pressure generated in the surge tank 10 as described above, the negative pressure of the surge tank 10 may or may not be applied according to each stroke of the cylinder. Therefore, the combination valve 40 also repeats the opening and closing. By such operation, there is a problem that the amount of air supplied to the exhaust manifold 70 is not constantly supplied.
또한 콤비네이션밸브(40)의 개폐작동을 서지탱크(10)의 부압에 의해 이루어지기 때문에 전체적인 장치들의 배치가 복잡해지고 부압에 대한 신뢰도가 떨어진다는 문제점이 있다.In addition, since the opening and closing operation of the combination valve 40 is performed by the negative pressure of the surge tank 10, the arrangement of the entire apparatus is complicated and the reliability of the negative pressure is low.
본 고안은 상기와 같은 문제점을 해결하기 위해 창작된 것으로서, 본 고안의 목적은 서지탱크의 부압에 의한 밸브 개폐작동 없이 ECU에 의해 일괄적이고 연속적인 공기공급이 이루어지도록 한 자동차의 배기계통 2차 공기 공급장치를 제공함에 있다.The present invention was created to solve the above problems, and an object of the present invention is to provide a secondary and continuous air supply system of an automobile in which a continuous and continuous air supply is made by an ECU without opening and closing a valve by a negative pressure of a surge tank. In providing a supply device.

When the combination valve is opened in the ECU for a certain period of time at the start-up, it is operated to forcibly supply the air purified by the air cleaner to the exhaust manifold by the air pump.
이하, 본 고안의 바람직한 실시예를 첨부된 도면을 참조하여 설명한다. 또한 본 실시예는 본 고안의 권리범위를 한정하는 것은 아니고, 단지 예시로 제시된 것이며 종래 구성과 동일한 부분은 동일한 부호 및 명칭을 사용한다.Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. In addition, the present embodiment is not intended to limit the scope of the present invention, but is presented by way of example only and the same parts as the conventional configuration using the same reference numerals and names.
도3은 본 고안에 의해 이루어진 2차 공기 공급장치를 도시한 블록구성도이다. 도3에 도시된 바와 같이 ECU(20)에서 제어하는 전기적인 신호에 의해 개폐작동되는 콤비네이션밸브(80)의 인포트(814)에는 공기펌프(60)가 연결되고 아웃포트(816)에는 배기다기관(70)이 연결된다. 그리고 공기를 정화하는 에어크리너(50)에는 공기펌프(60)가 연결되어 공기가 콤비네이션밸브(80)를 통해 배기다기관(70)으로 흐르도록 연결된다.Figure 3 is a block diagram showing a secondary air supply device made by the present invention. As shown in FIG. 3, an air pump 60 is connected to the inlet 814 of the combination valve 80 that is opened and closed by an electrical signal controlled by the ECU 20, and an exhaust manifold is connected to the outlet 816. 70 is connected. In addition, an air pump 60 is connected to the air cleaner 50 for purifying air so that air flows to the exhaust manifold 70 through the combination valve 80.
도4는 전기적인 신호에 의해 개폐되는 콤비네이션밸브(80)를 도시한 부분 단면도로써 일측에 공기의 흡입구인 인포트(814)가 형성되고 하측에 공기의 출구인 아웃포트(816)가 형성된 케이스(818)와, 케이스(818) 내부의 하측에 설치되며 포트(810)가 형성된 밸브시트(808)와, 밸브시트(808)의 포트(810)를 개폐하기 위한 스토퍼(806)와, 스토퍼(806)의 상부에 형성된 자성체(812)와, 케이스(818) 상부에 형성되어 전기를 공급받으면 자력을 발생하는 솔레노이드장치(802)와, 자성체(812)와 솔레노이드장치(802)사이에 형성된 스프링(804)을 포함하여 이루어진다.4 is a partial cross-sectional view of the combination valve 80 that is opened and closed by an electrical signal, and an inlet 814, which is an air inlet, is formed at one side, and an outlet 816, which is an outlet of air, is formed at one side thereof. 818, a valve seat 808 provided below the case 818, and having a port 810, a stopper 806 for opening and closing the port 810 of the valve seat 808, and a stopper 806. Magnetic body 812 formed on the upper part of the upper part of the case), and a solenoid device 802 formed on the case 818 to generate magnetic force when supplied with electricity, and a spring 804 formed between the magnetic body 812 and the solenoid device 802. )
상기와 같이 이루어진 콤비네이션밸브(80)의 작용을 설명하면 전기적인 신호를 입력받으면 솔레노이드장치(802)에 자력이 발생되어 자성체(812)를 끌어당겨 스토퍼(806)가 상승된다. 이 때 밸브시트(808)에 형성된 포트(810)를 통해 공기가 인포트(814)에서 아웃포트(816)로 흐르게 된다. 그리고 전기적인 신호가 끊기면 솔레노이드장치(802)에 발생된 자력이 상실되어 스프링(804)의 복원력에 의해 스토퍼(806)는 다시 하강하여 포트(810)를 막게 됨으로 공기의 흐름이 차단된다.Referring to the operation of the combination valve 80 made as described above, when the electrical signal is received, the magnetic force is generated in the solenoid device 802 to attract the magnetic material 812, the stopper 806 is raised. At this time, air flows from the inlet 814 to the outlet 816 through the port 810 formed in the valve seat 808. When the electrical signal is cut off, the magnetic force generated in the solenoid device 802 is lost, and the stopper 806 is lowered again by the restoring force of the spring 804 to block the port 810, thereby blocking the flow of air.
상기와 같이 전자제어에 의해 개폐되는 콤비네이션밸브(80)를 사용하는 2차 공기 공급장치의 작동을 설명하면 다음과 같다.Referring to the operation of the secondary air supply device using the combination valve 80 that is opened and closed by the electronic control as described above are as follows.
시동초기의 약1분에서 2분가량의 시간동안에 발생되는 배기가스는 불완전 연소되는 경우가 많아 배기가스 중에 포함된 유해한 탄화수소와 일산화탄소를 연소시키기 위해 ECU(20)에서 콤비네이션밸브(80)를 개방하여 에어크리너(50)에 의해 정화된 공기를 공기펌프(60)를 통해 일정하고 연속적으로 공기를 배다기관으로 공급하게 된다.The exhaust gas generated during a period of about one to two minutes from the beginning of the start-up is often incompletely burned, so the combination valve 80 is opened in the ECU 20 to burn harmful hydrocarbons and carbon monoxide contained in the exhaust gas. The air purified by the air cleaner 50 is supplied to the exhaust pipe through the air pump 60 in a constant and continuous manner.
2차 공기를 일정시간 계속주입하다 일정시간이 경과하면 ECU(20)에서 콤비네이션밸브(80)를 닫게 되면 배기다기관(70)으로의 공기공급이 차단된다.While the secondary air continues to be injected for a predetermined time, when a certain time elapses, when the combination valve 80 is closed in the ECU 20, the air supply to the exhaust manifold 70 is cut off.
상기한 바와 같이 본 고안은 배기다기관으로의 공기공급을 부압에 의해 제어하는 것이 아니고 전기적인 신호에 의해 제어함으로써 부압을 전달하기 위한 장치를 설치하지 않아도 가능하기 때문에 장치의 배치가 간단하다는 이점과 가격절감의 효과가 있다.As described above, the present invention does not control the supply of air to the exhaust manifold by the negative pressure, but does not require the installation of a device for transmitting the negative pressure by controlling the electrical signal. There is a saving effect.
그리고 전기적인 신호에 의해 공기공급을 제어하기 때문에 공기공급의 신뢰성이 향상된다는 이점이 있다.And since the air supply is controlled by an electrical signal, there is an advantage that the reliability of the air supply is improved.
