関の排気微粒子処理装置。In an exhaust particulate treatment device for an internal combustion engine, which includes a trap installed in an exhaust passage to collect particulates in the exhaust, a catalyst attached to the trap communicates with the exhaust passage upstream and downstream of the trap, bypassing the trap. This serves as the exhaust bypass passage and the active area of the catalyst. Exhaust temperature state detection means for detecting a state of exhaust gas temperature equal to or higher than a predetermined value; and a signal from the means is inputted to allow exhaust gas to flow through the trap when the exhaust temperature is equal to or higher than a predetermined value; An exhaust particulate treatment device for an internal combustion engine, comprising: a switching valve device that selectively opens and closes an exhaust passage and an exhaust bypass passage so that exhaust gas flows through the exhaust bypass passage when the above condition occurs.
