More Information
Summary:An exhaust purification apparatus of an engine, which can regulate the temperature (Te1) of an exhaust purification catalyst (52) appropriately and which can release components of an exhaust efficiently by a regeneration process, is provided. When the regeneration process is performed by a regeneration process execution means (71), the oxygen concentration of the exhaust at the time of supply of hydrocarbon by the regeneration process execution means is adjusted, as appropriate, in accordance with a temperature difference (Te3) between the temperature of the exhaust purification catalyst and a set temperature (Te2).
