摘要： PROBLEM TO BE SOLVED: To implement the regeneration processing of a DPF without a need of a compressor for combustion air supply. SOLUTION: A throttle valve 5 is provided to an intake flow passage 4 of an engine body 1. A burner 8 for DPF regeneration processing is provided at the upstream side position of an installed position of the DPF 7 in an exhaust gas flow passage 6. A bypass line 12 branched from the upstream side position of an installed location of the throttle valve 5 in the intake flow passage 4 is connected to the combustor 9 of the burner 8. When regeneration processing of the DPF 7 is performed, an air 13 of which pressure is increased within the intake flow passage 4 on the upstream side by throttling the throttle valve 5 is guided through the bypass line 12 to the combustor 9 of the burner 8 serving as a combustion air. Thereby the burner 8 is operated, and a temperature of the DPF 7 is increased by a high-temperature combustion gas 18 produced by the burner 8, and thus deposited PM is burnt and removed.
