본 고안은 차량용 증발가스 제어장치와 배기가스 재순환장치의 통합제어장치에 관한 것이다.The present invention relates to an integrated control device for a vehicle evaporative gas control device and exhaust gas recirculation device.
주지하는 바와 같이 차량에서 배출되는 가스는 그 배출원에 따라 증발가스, 배기가스, 블로바이가스로 구분되며, 상기한 가스중 증발가스는 증발가스 제어장치를 사용하고, 배기가스에 포함된 질소산화물은 배기가스 재순환장치를 사용하여 이를 저감시키고 있다.As is well known, the gas discharged from the vehicle is classified into evaporation gas, exhaust gas, and blow-by gas according to the emission source. The evaporation gas in the gas is an evaporation gas control device, and the nitrogen oxide contained in the exhaust gas is Exhaust gas recirculation equipment is used to reduce this.
즉 이들은 제3도에 도시한 바와 같이 연료탱크(미도시)에서 생성된 증발가스는 이를 캐니스터(30)의 활성탄에 흡착 저장하였다가 엔진의 정상작동중에 제어장치(ECU)(31)의 명령에 의하여 퍼지콘트롤밸브(솔레노이드밸브)(32)가 열리면 증발가스는 활성탄에서 분리되어 스로틀보디(33)로 유입되어 연소시키고, 배기가스 재순환장치는 배기파이프(미도시)와 스로틀보디(33) 사이를 도관(미도시)으로 연결하고 도관에 배기가스 재순환(EGR)밸브(40)를 설치하여 엔진에 비교적 농후한 혼합기가 공급될 때를 제외하고 제어장치(ECU)(31)에 의하여 EGR 밸브를 열어서 스로틀보디(33)에 유입하여 동력행정시의 연소온도를 낮추므로서 질소산화물의 발생량을 저감시키는 것이다.That is, they are adsorbed and stored in the activated carbon of the canister 30 as the boil-off gas generated in the fuel tank (not shown) as shown in FIG. 3 and then, at the command of the control unit (ECU) 31 during normal operation of the engine. When the purge control valve (solenoid valve) 32 is opened, the boil-off gas is separated from the activated carbon and flows into the throttle body 33 for combustion, and the exhaust gas recirculation device is connected between the exhaust pipe (not shown) and the throttle body 33. By connecting the conduit (not shown) and installing an exhaust gas recirculation (EGR) valve 40 in the conduit, the EGR valve is opened by the control unit (ECU) 31 except when a relatively rich mixer is supplied to the engine. The amount of nitrogen oxide generated is reduced by flowing into the throttle body 33 and lowering the combustion temperature during power administration.
그러나 상기 증발가스 제어장치와 배기가스 재순환장치는 각각 별개로 되어 있으므로 그 구조가 복잡하고 솔레노이드밸브(32)가 개폐될 때 소음이 발생하며, 제어장치(ECU)의 제어로조직(logic) 개발에 많은 비용이 소요되고 있는 문제점이 있는 것이다.However, since the boil-off gas control device and the exhaust gas recirculation device are separate from each other, the structure is complicated and noise occurs when the solenoid valve 32 is opened and closed, and the control unit (ECU) controls the development of logic. There is a problem that is costly.
본 고안은 상기한 문제점을 시정하여 구조를 단순화하고 소음의 발생을 줄일 수 있는 차량용 증발가스 제어장치와 배기가스 재순환장치의 통합제어장치를 제공하는 것을 목적으로 한다.The object of the present invention is to provide an integrated control device for a vehicle evaporative gas control device and an exhaust gas recirculation device that can simplify the structure and reduce the occurrence of noise by correcting the above problems.
본 고안은 상기한 목적을 달성하기 위하여 연료탱크에서 생성된 증발가스를 흡착저장하는 캐니스터의 증발가스도관에 첵크밸브를 설치하고, 배기매니폴드에 설치된 배기가스 재순환도관에 배기가스 재순환밸브를 설치하여 증발가스도관과 배기가스 재순환도관을 통합도관에 연결하며, 상기 통합도관을 냉각수온에 의하여 개폐되는 수온밸브를 경유하여 스로틀보디에 연결한 것이다.The present invention provides a check valve in the evaporation gas conduit of the canister for adsorption and storage of the evaporated gas generated in the fuel tank, and by installing an exhaust gas recirculation valve in the exhaust gas recirculation conduit installed in the exhaust manifold to achieve the above object. An evaporation gas conduit and an exhaust gas recirculation conduit are connected to the integrated conduit, and the integrated conduit is connected to the throttle body via a water temperature valve that is opened and closed by cooling water temperature.
이하, 실시예를 도면에 의하여 설명한다.An embodiment is described below with reference to the drawings.
본 고안은 제1도 및 제2도에 도시한 바와 같이 연료탱크(1)에서 생성된 증발가스를 흡착저장하는 캐니스터(2)의 증발가스도관(3)에 첵크밸브(4)를 설치하고, 배기매니폴드(5)에 설치된 배기가스 재순환도관(6)에 배기가스 재순환밸브(7)를 설치하여 증발가스도관(3)과 배기가스 재순환도관(6)을 통합도관(8)에 연결하며, 상기 통합도관(8)을 냉각수온도에 의하여 개폐되는 수온밸브(9)를 경유하여 스로틀보디(10)에 연결하여서 된 것이다.In the present invention, as shown in FIGS. 1 and 2, the check valve 4 is installed in the boil-off gas conduit 3 of the canister 2 that absorbs and stores the boil-off gas generated in the fuel tank 1, An exhaust gas recirculation conduit (6) is installed in the exhaust gas recirculation conduit (6) installed in the exhaust manifold (5) to connect the boil-off gas conduit (3) and the exhaust gas recirculation conduit (6) to the integrated conduit (8), The integrated conduit 8 is connected to the throttle body 10 via the water temperature valve 9 which is opened and closed by the coolant temperature.
이상과 같은 본 고안은 냉각수 온도가 60℃ 이하일 때에는 증발가스도관(3)에 설치된 첵크밸브(4)와 배기가스 재순환도관(6)에 설치한 배기가스 재순환밸브(7)는 닫혀있다가 냉각수온도가 60℃ 이상일 때 수온밸브(9)가 통합도관(8)을 개방하므로서 스로틀보디(10)의 부압에 의하여 상기 첵크밸브(4)와 배기가스 재순환밸브(7)가 열리고 증발가스와 배기가스가 스로틀보디(10)에 유입되어 연소실에 공급되며 이때 첵크밸브(4)는 캐니스터(2)로 배기가스가 역류하는 것을 방지하는 것이다. 상기와 같이 공급된 증발가스는 연소실에서 재연소되고 증발가스는 연소작용은 하지 않으나 연소온도를 낮추므로서 질소산화물의 발생을 저감하는 것이다.The present invention as described above, when the coolant temperature is 60 ℃ or less, the check valve (4) installed in the boil-off gas conduit (3) and the exhaust gas recirculation valve (7) installed in the exhaust gas recirculation conduit (6) is closed, but the coolant temperature Is above 60 ° C, the water temperature valve 9 opens the integrated conduit 8 so that the check valve 4 and the exhaust gas recirculation valve 7 are opened by the negative pressure of the throttle body 10, and the evaporation gas and the exhaust gas The throttle body 10 is supplied to the combustion chamber and the check valve 4 prevents the exhaust gas from flowing back into the canister 2. The boil-off gas supplied as described above is re-burned in the combustion chamber and the boil-off gas does not burn, but reduces the generation of nitrogen oxides by lowering the combustion temperature.
이상과 같이 본 고안은 증발가스도관과 배기가스 재순환도관을 통합도관에 연결하고, 통합도관에 수온밸브를 설치하여 냉각수온도에 의하여 통합도관을 수온밸브가 개폐되도록 하였으므로 그 제어구조가 종래의 전자식제어에서 기계식제어로 전환되어서 구조가 단순화되어 원가를 절감함과 동시에 작업성이 향상되고 내구성과 신뢰성이 확보되는 것이다. 또한 솔레노이드 밸브를 제거하므로서 소음이 현저하게 감소되며 배출가스 저감효과도 양호한 효과 등이 있는 것이다.As described above, the present invention connects the boil-off gas conduit and the exhaust gas recirculation conduit to the integrated conduit, and installs the water temperature valve in the integrated conduit so that the integrated conduit opens and closes the water temperature valve by the coolant temperature. By switching from to mechanical control, the structure is simplified to reduce cost, improve workability, and ensure durability and reliability. In addition, the noise is significantly reduced by removing the solenoid valve, and the effect of reducing the exhaust gas is also good.
