装置。 a trap device installed in the exhaust passage to collect particulate matter in the exhaust; a burner device to burn the collected particulate matter in the trap device; and a trap device between the exhaust passage and the trap device between the trap device and the muffler. In a device comprising a bypass passage communicating with an exhaust passage on the upstream side, a first switching valve is provided at the upstream connection part of the bypass passage and the exhaust passage, and a second switching valve is provided in the exhaust passage between the trap device and the muffler. Provided with a switching valve,
During normal operation of the engine, the first switching valve closes the bypass passage inlet, and the second switching valve communicates the trap device and the muffler, and when the burner device operates, the first switching valve closes the bypass passage inlet. A particulate collection device characterized in that the bypass passage inlet is opened, the exhaust passage upstream of the burner device is closed, and communication between the trap device and the muffler is cut off by a second switching valve.
