Claims (1)
燃焼室に還流させて、排気ガス中のＮＯｘ濃度を
減少させるデイーゼルエンジン用排気ガス再循環
システムにおいて、吸気系統に前記再循環ガスが
還流されない気筒を設け、当該気筒の排気ガスの
みを他の気筒に再循環ガスとして還流させるよう
にしたことを特徴とするデイーゼルエンジン用排
気ガス再循環システム。 In an exhaust gas recirculation system for a diesel engine that reduces the concentration of NOx in the exhaust gas by circulating a portion of the exhaust gas back into the combustion chamber of the engine as a recirculation gas, the intake system includes a cylinder to which the recirculation gas is not returned. 1. An exhaust gas recirculation system for a diesel engine, characterized in that the exhaust gas recirculation system for a diesel engine is provided so that only the exhaust gas of the cylinder concerned is recirculated to other cylinders as recirculation gas.
