(57) [Summary] To improve the exhaust purification performance of an internal combustion engine (diesel engine). In an area where operation of a diesel engine mounted on a parallel hybrid vehicle is required, an operating point of the engine collects PM collected by a DPF (diesel particulate filter) disposed in an exhaust passage. D The region II was set to be capable of self-regeneration by purifying by continuous combustion using NO 2 generated by oxidation of an oxidation catalyst disposed upstream of the PF. |
