関の排気微粒子処理装置。 A trap with a catalyst that collects exhaust particles in the exhaust gas in the exhaust passage of an internal combustion engine, an exhaust bypass passage that bypasses the trap with a catalyst, an on-off valve that opens and closes the exhaust bypass passage, and a trap with a catalyst installed on the upstream side. In an exhaust particulate treatment device equipped with a heater device that heats incoming exhaust gas to promote combustion of exhaust particulates, when the amount of accumulated exhaust particulates collected in a trap with a catalyst exceeds a predetermined amount, the exhaust temperature is set. 1. An exhaust particulate treatment device for an internal combustion engine, which detects that the internal combustion engine is in a deceleration operating state within a value range, opens an on-off valve, and operates a heater device for a predetermined period of time.
