Internal combustion engine having lean NOx catalyst |
摘要 |
An internal combustion engine having a lean NOx catalyst 39 is capable of relieving a load upon an engine fuel injection device by eliminating the use of sub-injection, and of well purifying an exhaust gas and recovering from S-poisoning even by eliminating the use of the sub-injection. The internal combustion engine has a combustion heater 17 for allowing a flow of combustion gas through an engine intake passageway 23 to raise temperatures of engine related elements, a lean NOx catalyst 39 provided in an engine exhaust passageway 42 for purifying an engine exhaust gas, and a combustion gas introducing passageway 99 for introducing at least some proportion of a combustion gas emitted by the combustion heater 17, toward upstream of the lean NOx catalyst 39 in the engine exhaust passageway 42 from the engine intake passageway 23 when making a request for a reproducing process of the lean NOx catalyst 39. <IMAGE> |
