摘要： PROBLEM TO BE SOLVED: To provide an exhaust emission control device for a cylinder injection type internal combustion engine capable of preventing CO, THC spike and NOx spike by surely balancing reactions of emission and reduction in purging NOx in addition to shortening of NOx purging period. SOLUTION: When NOx of NOx catalyst should be emitted, stratified combustion is performed with a stoichiometric or slightly rich air-fuel ratio (14.42 in the figure) by injecting fuel in compression stroke, and a large quantity of CO, HC is thereby produced near a spark plug by incomplete combustion, while a large quantity of O2 of a lean air-fuel ratio is made to remain around there. The reactions of emission and reduction of NOx with CO, HC on the NOx catalyst and oxidation of CO, HC are mixed by feeding CO, HC and O2 to the NOx catalyst, and an amount of CO, HC contributing to the emission and reduction of NOx is decreased. Emission velocity of NOx is thereby decreased to surely reduce NOx, and excessive CO, HC to emitted NOx are oxidized with O2 to purify.
