Abstract

Abstract Translated from Japanese (57)【要約】 【構成】 4サイクルガソリンエンジンから排出され る排気ガスを該排気ガスの流路に配設された触媒に接触 させることからなる排気ガスの浄化方法において、前記 エンジンのシリンダー内に吸入された混合気の一部を意 図的に燃焼させることなく前記排気ガスの流路に供給す ることを特徴とする、排気ガスの浄化方法。 【効果】 排気ガス流路の途中に配設された浄化触媒 に、従来の方法のように特別な燃料供給装置を設置する ことなくNOx の還元剤としてHCを供給することができ る。これによって、排気ガスのNOx 浄化性能を高めるこ とができる。 (57) [Summary] [Structure] A method for purifying exhaust gas, which comprises contacting exhaust gas discharged from a four-cycle gasoline engine with a catalyst disposed in a flow path of the exhaust gas, A method for purifying exhaust gas, characterized in that a part of the air-fuel mixture sucked into the exhaust gas is supplied to the flow path of the exhaust gas without being intentionally burned. [Effect] It is possible to supply HC as a NOx reducing agent to the purifying catalyst disposed in the middle of the exhaust gas flow path without installing a special fuel supply device unlike the conventional method. This can improve the NOx purification performance of the exhaust gas.
