浄化装置。 In a diesel engine exhaust purification device in which a particulate trap filter is installed downstream of the exhaust brake shutter in the engine exhaust passage, a bypass passage is provided that branches from the exhaust passage downstream of the exhaust brake shutter and bypasses the trap filter. In addition to installing a switching valve that selectively opens and closes the trap filter side and the bypass passage side,
1. An exhaust purification device for a diesel engine, comprising a controller that controls a switching valve to open a bypass passage for a predetermined period of time when the exhaust brake is released.
