Japanese Patent JP4095979
Kind Code:
B2
Abstract:
When the temperature of exhaust gas control means ( 3 ), which is provided in an exhaust passage ( 2 ) of an internal combustion engine ( 1 ) and which has oxidation function, is increased to a target temperature in order to recover an exhaust gas control ability of the exhaust gas control means ( 3 ), the method of increasing the temperature of the exhaust gas control means ( 3 ) is switched between a method in which the temperature of the exhaust gas control means ( 3 ) is increased by controlling an amount of fuel supplied to the exhaust gas control means ( 3 ) and a method in which the fuel supply to the exhaust gas control means ( 3 ) is prohibited and the temperature of the exhaust gas control means ( 3 ) is increased by controlling an amount of air taken in the internal combustion engine ( 1 ), based on an operation state of the internal combustion engine ( 1 ).
