摘要: An exhaust purification system of an internal combustion engine, which includes: a silver-alumina-based catalyst, which is arranged in an engine exhaust system and, when an air-fuel ratio of exhaust gas is leaner than a stoichiometric air-fuel ratio, releases adsorbed NO2 at a first set temperature and adsorbed NO at a second set temperature, a secondary air feed passage configured to suppress a temperature rise of the silver-alumina-based catalyst; and an electronic control unit, that: controls the air flow through the secondary air feed passage to: when the silver-alumina-based catalyst has reached a third set temperature, suppress a temperature rise of the silver-alumina-based catalyst to maintain the silver-alumina-based catalyst near the third set temperature, and then lift the suppression of the temperature rise of the silver-alumina-based catalyst so that at least part of the NO adsorbed at the silver-alumina-based catalyst, is oxidized to NO2 to be adsorbed at the silver-alumina-based catalyst.

摘要: A wall flow type particulate filter is arranged inside the exhaust passage of an internal combustion engine where combustion is performed under an excess of oxygen. The particulate filter carries a solid acid. The solid acid has an acid strength which is higher than the acid strength of sulfurous acid and lower than the acid strength of sulfuric acid. To remove the ash from the particulate filter, ash atomization processing for rendering the state of the particulate filter a state where the exhaust gas which flows into the particulate filter is lowered in concentration of oxygen and the particulate filter is raised in temperature is temporarily performed.

摘要: An exhaust purification system in which when an air-fuel ratio of exhaust gas is leaner than a stoichiometric air-fuel ratio, a silver-alumina-based catalyst device releases adsorbed NO2 at a first set temperature and releases adsorbed NO at a second set temperature which is lower than the first set temperature. When the air-fuel ratio of the exhaust gas is leaner than the stoichiometric air-fuel ratio and the silver-alumina-based catalyst device is a third set temperature which is lower than the second set temperature, a temperature rise of the silver-alumina-based catalyst device is suppressed to maintain the silver-alumina-based catalyst device near the third set temperature, and at least part of the NO which is adsorbed at the silver-alumina-based catalyst device is oxidized to NO2 to be adsorbed at the silver-alumina-based catalyst device, then the suppression of the temperature rise of the silver-alumina-based catalyst device is lifted.
