자동차용 ＥＧＲ믹싱 하우징{EGR mixing housing for automobile}EBR mixing housing for automobile {EGR mixing housing for automobile}

본 발명은 자동차용 EGR(exhaust-gas recirculation)믹싱 하우징에 관한 것으로서, 더욱 상세히는 외부의 새로운 공기와 엔진으로부터 배출된 EGR가스를 혼합하여, 다시 자동차 엔진의 인테이크 시스템으로 유입시키는 EGR믹싱 하우징의 믹싱구간 중 일 부위에 둔턱부를 형성하고, 둔턱부 내부에 EGR가스 믹싱용 포켓이 형성되는 EGR가스 믹싱포트를 구비하되, 몸체부와 EGR가스 믹싱포트가 일정거리 이격되도록 차단막을 형성하며, 둔턱부의 일측에 엔진에서 배출된 EGR가스가 EGR 믹싱포트로 유입되는 EGR가스 유입홀을 형성하여, 몸체부를 통과하는 새로운 공기와 EGR가스 유입홀을 통해 유입되는 EGR가스가 EGR 믹싱포트에서 고르게 혼합되어 인테이크 메니폴더로 유입될 수 있도록 한 자동차용 EGR믹싱 하우징에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exhaust-gas recirculation (ECR) mixing housing for automobiles, and more particularly to mixing an EGR mixing housing for mixing external fresh air and EGR gas discharged from an engine and introducing the same into an intake system of an automobile engine. A barrier is formed at one portion of the section, and an EGR gas mixing port is formed in which the pocket for EGR gas mixing is formed. The barrier film is formed so that the body portion and the EGR gas mixing port are separated by a predetermined distance. The EGR gas discharged from the engine forms an EGR gas inlet hole into the EGR mixing port. The new air passing through the body and the EGR gas flowing through the EGR gas inlet hole are evenly mixed in the EGR mixing port. The present invention relates to an EGR mixing housing for an automobile that can be introduced into a car.

일반적으로 배기가스 재순환장치인 EGR장치는, 연소 후 배출되는 배기가스속의 질산산화물을 감소시키기 위해 실린더에서 스로틀바디 부분에 위치한 흡입다기관 포트로 재순환시켜 가능한한 출력감소를 최소로 하면서 최고연소온도를 낮추어 NOX의 배출량을 감소시킨다.In general, EGR, an exhaust gas recirculation device, is recycled from the cylinder to the intake manifold port located in the throttle body to reduce the nitrate oxide in the exhaust gas discharged after combustion. Reduces NOx emissions

혼합기에 공기중의 질소(N2)에 비해 열용량이 큰 이산화탄소(CO2)가스를 함유한 배출가스를 적절한 혼입하면 동일한 발열량의 연소를 하더라도 배출가스를 혼입하지 않는 경우에 비하여 연소온도가 내려가 질소산화물(NOX)의 발생을 억제할 수 있기 때문에 배출가스 EGR장치는 질소산화물(NOX) 저감장치로 많이 이용되고 있다.When the exhaust gas containing carbon dioxide (CO2) gas having a larger heat capacity than the nitrogen (N2) in the air is properly mixed into the mixer, the combustion temperature is lowered compared to the case where the exhaust gas is not mixed even if the same calorific value is burned. Since the generation of NOX) can be suppressed, the exhaust gas EGR apparatus is widely used as a nitrogen oxide (NOX) reduction apparatus.

한편, 배출가스를 연소실내로 재순환할 경우 혼합기의 착화성이나 엔진출력은 떨어지기 때문에 질소산화물(NOX)의 배출량이 많은 중속 운전영역을 선택하여 배기가스 재순환을 실시하여야 한다.On the other hand, when the exhaust gas is recycled into the combustion chamber, the ignition of the mixer and the engine output are reduced, so the exhaust gas recirculation should be performed by selecting a medium speed operation region having a large amount of NOx.

배출가스 재순환 제어량의 지표로서 EGR율이 사용된다.The EGR rate is used as an indicator of the exhaust gas recirculation control amount.

The engine efficiency is reduced because EGR gas flowing through is not uniformly mixed but simply meets and flows into the intake system. An object of the present invention is to provide an EGR mixing housing for an automobile that can effectively solve the problem.
