摘要： PROBLEM TO BE SOLVED: To regenerate DPF 17 in a short time without fusing the DPF 17 and worsening the rate of fuel consumption. SOLUTION: When the amount of particulates accumulated on the DPF 17 is a preset value or larger, subsidiary injection control for injecting fuel in an expansion stroke after main injection of the fuel is executed to supply unburnt fuel to an oxidation catalyst 16 so that the temperature of exhaust gas flowing into the DPF 17 is increased by the oxidizing reaction to burn and remove the particulates. At first, a subsidiary injection amount is controlled depending on the operated condition of an engine, and after the temperature of the DPF 17 is increased, the subsidiary injection amount is feedback controlled so that the temperature of the DPF 17 gets to a target temperature.
