Exhaust gas recirculation system of car with purification function

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exhaust gas recirculation apparatus of a vehicle having a purification function, wherein a part of the combustion gas from a combustion chamber to a surge tank is reduced between a combustion chamber and a surge tank in order to reduce harmful components such as nitrogen oxides of the exhaust gas in the engine exhaust gas. By disposing the purifying means in all stages of the EGR valve on the EGR pipeline, it is possible to effectively reduce the carbon and oil contained in the combustion gas so as to prevent malfunction of various valves mounted on the surge tank. There is a purpose.;In order to achieve the above object, the present invention is provided so that both ends thereof communicate with the surge tank 3 and the combustion chamber 1, respectively, on the intake manifold 2 forming the intake passage in the combustion chamber 1, respectively. In the exhaust gas recirculation apparatus of an automobile composed of an EGR line (4) and an EGR valve (5) mounted on the EGR line (4), in the EGR line (4) to which the EGR valve (5) is mounted. An EGR line 4 adjacent to the combustion chamber 1 has a housing 8 connected at both ends through the EGR line 4 and a pipe member 7, and an element mounted inside the housing 8. It is characterized in that the purifying means (6) consisting of 9) is installed.
