Abstract

An exhaust gas recirculation apparatus for a vehicle is provided to actively burn carbon particles stuck to an inner surface of an exhaust valve to remove harmful components. An exhaust gas recirculation apparatus for a vehicle includes an exhaust manifold(2), an exhaust pipe(3), a cooler(4), an exhaust valve(5), a suction manifold(6), a combustion chamber(7), an introduction pipe(8), an exhaust pipe(9), a guide pipe(10), and a recycling valve(11). The exhaust manifold exhausts an exhaust gas through the exhaust pipe. The cooler cools the exhaust gas. The exhaust valve is opened or closed to control flow of the exhaust gas to introduce the exhaust gas into the suction manifold with the new air. The combustion chamber re-burns the exhaust gas. The introduction pipe introduces the exhaust gas. The exhaust pipe is in communication with the guide pipe and opened or closed by the recycling valve.

본 발명은 차량용 배기가스의 재순환장치에 관한 것으로서, 보다 상세하게는 엔진의 각 실린더에서 배출되는 배기가스를 재순환시키어 대기오염물질의 배출을 절감하고, 엔진의 각 실린더에서 배기되는 배기가스의 재순환시에 배기냉각쿨러의 내부와 배기밸브의 내측면에 배기가스의 매연물질이 침적 퇴적된 카본입자를 원활하게 연소시켜 유해성분을 제거하여 배출시킬 수 있도록 된 차량용 배기가스의 재순환장치에 관한 것이다.The present invention relates to a vehicle exhaust gas recirculation apparatus, and more particularly, to reduce the emission of air pollutants by recycling the exhaust gas discharged from each cylinder of the engine, and at the time of recycling the exhaust gas exhausted from each cylinder of the engine The present invention relates to a vehicle exhaust gas recirculation apparatus capable of smoothly burning carbon particles in which exhaust gas soot accumulated and deposited on the inner side of an exhaust valve and removing harmful components.

일반적으로 엔진의 각 실린더에서 배출되는 배기가스에는 환경에 유해간 탄화수소를 포함한 각종 대기 오염물질이 포함되어 있어, 배출되는 배기가스를 다시 연소실로 강제적으로 보내어 재연소시킴으로서 대기중으로 방출되는 오염물질을 절감하는 배기가스 재순환장치가 구비되어 있다.In general, the exhaust gas emitted from each cylinder of the engine contains various air pollutants including hydrocarbons harmful to the environment, thereby reducing the pollutants emitted to the atmosphere by forcibly sending the exhaust gas back to the combustion chamber for reburn. An exhaust gas recirculation device is provided.

상기에서 배기가스 재순환장치(50)는 일반적으로 도4에서 도시된 바와 같이 엔진의 배기매니폴더(51)를 통해 배출되는 배기가스를 배출파이프(52)를 통해 냉각쿨러(53)를 통과시켜 냉각시킨 다음 배기밸브(54)의 개폐에 의해 배기엘보우(55)로 유입되고 흡기매니폴더로 공급되어 신기와 혼합된 다음 연소실로 유입 재연소되도록 되어 있다.In the exhaust gas recirculation apparatus 50, as shown in FIG. 4, the exhaust gas discharged through the exhaust manifold 51 of the engine is cooled by passing the cooling cooler 53 through the exhaust pipe 52. After the exhaust valve 54 is opened and closed, the exhaust valve 54 is introduced into the exhaust elbow 55, supplied to the intake manifold, mixed with the new air, and then reintroduced into the combustion chamber.

상기와 같은 배기가스 재순환은 운전조건 중 저속 부분 부하 구간에서 작동을 하는바, 즉 저속 고부하 및 고속 고부하 영역에서는 배기밸브(54)가 폐쇄되어 배기가스의 재순환이 이루어지지 않도록 되어 있다.The exhaust gas recirculation as described above operates in the low-speed partial load section of the operating conditions, that is, the exhaust valve 54 is closed in the low speed high load and high speed high load regions so that the exhaust gas is not recycled.

상기와 같은 저속 부분 부하 영역에서 배기가스의 온도는 250∼400℃ 정도로서 배기밸브(54)를 통해 흡기매니폴더로 유입되는 배기가스에 포함되어 완전 연소되지 않은 매연물질이 배기밸브(54)의 내측면에 침적되어 퇴적되고, 냉각쿨러(53)의 내면에도 침적 퇴적되어 카본 퇴적물을 이루게 된다.In the low-speed partial load region as described above, the exhaust gas has a temperature of about 250 to 400 ° C., and the exhaust gas flowing into the intake manifold through the exhaust valve 54 is not completely burned so that the exhaust gas is not completely burned. It is deposited on the side and deposited, and also deposited on the inner surface of the cooling cooler 53 to form a carbon deposit.

이와 같은 카본 퇴적물은 배기밸브(54)의 마모와 손상을 주게되며 냉각쿨러(53)의 경우 냉각수와의 열교환을 방해하여 냉각쿨러(53)의 냉각성능을 저하시켜는 문제점을 유발한다.Such carbon deposits may cause wear and damage of the exhaust valve 54, and in the case of the cooling cooler 53, the heat exchange with the cooling water may be hindered, thereby causing a problem of lowering the cooling performance of the cooling cooler 53.

상기와 같은 문제점을 해결하기 위하여 배기밸브(54)에 퇴적된 카본물질을 외부로 배출하기 위해 도 5에서 도시된 바와 같이 배기밸브(54) 개폐시에 배기밸브(54)를 짧은시간(약 2초)동안 3회정도로 풀 온/오프시켜므로써 밸브(56)와 밸브내측면(57)이 부딪히는 충격에 의해 퇴적된 카본물질이 자유낙하하여 밸브내측면(57)에서 퇴적되지 않도록 하고 있으나, 이것은 떨어진 카본물질이 저속 부분 구간에서 대기가스의 재순환시에 배기밸브(54)가 개방되면서 모두 연소실로 유입되게 되어 유입되는 카본퇴적물질이 불완전연소 및 노킹을 유발하여 엔진의 내구성을 떨어트리는 또 다른 문제점을 유발하고 있다.In order to solve the above problems, in order to discharge the carbon material deposited on the exhaust valve 54 to the outside, as shown in FIG. By pulling on / off about 3 times per second), the carbon material deposited by the impact of the valve 56 and the valve inner surface 57 collides freely and is not deposited on the valve inner surface 57. Another problem is that the fallen carbon material is introduced into the combustion chamber as the exhaust valve 54 is opened during the recirculation of atmospheric gas in the low-speed part section, and the inflow carbon deposit causes incomplete combustion and knocking, thereby degrading the durability of the engine. Is causing.
