Abstract
본 발명의 배기가스 온도가 일정온도 이하일 때 촉매장치가 제대로 작동하지 않아 유해가스가 그대로 방출됨을 방지하기 위한 엔징의 배기 정화 장치와 방법에 관한 것이다. 배기가스의 온도가 일정온도이하일 경우에는 촉매장치가 정상동작이 이루어지지 않는 바, 촉매장치가 작동하지 않게 되면 CO,HC, NOx등의 환원작용을 잘 이루어지지 못하므로서, 정화율이 떨어져 유해한 가스가 그대로 차량의 외부로 방출되어지게 된다. 본 고안에 서는 이와같은 종래의 문제점을 해결하기 위하여 일정속도이상에서 배기가의 온도가 일정온도 이하일 경우 연료공급을 줄여 촉매장치의 정상동작이 이루어지도록 유도하여 주므로서, 배기가스가 그대로 차량의 외부로유출됨을 방지하고자 하는 것이다.When the exhaust gas temperature of the present invention is below a certain temperature, the catalyst device does not operate properly, and relates to an exhaust purification apparatus and method of the engine to prevent the harmful gas is released as it is. If the temperature of the exhaust gas is below a certain temperature, the catalyst device does not operate normally. If the catalyst device is not operated, CO, HC, NOx, etc. cannot be reduced, and thus the purification rate is low and harmful gas is lost. Is released to the outside of the vehicle as it is. In the present invention, in order to solve such a conventional problem, when the exhaust gas temperature is above a certain speed at a certain speed or less, the fuel supply is reduced to induce the normal operation of the catalyst device, so that the exhaust gas is directly outside the vehicle. This is to prevent leakage.
