理装置。 An exhaust particulate treatment device for an internal combustion engine in which a trap with a catalyst for collecting particulates in the exhaust gas is interposed in an exhaust passage, an exhaust bypass passage bypassing the trap with a catalyst, and an engine rotation speed detection means for detecting the engine rotation speed. and an engine load detection means for detecting an engine load, and when both the detection means detect a pre-known engine load and rotational speed at which the exhaust gas temperature exceeds a predetermined value, the exhaust gas is caused to flow through the catalyst trap. On the other hand, an exhaust particulate treatment device for an internal combustion engine, comprising a switching valve device that selectively opens and closes the exhaust passage and the exhaust bypass passage so that the exhaust gas otherwise flows through the exhaust bypass passage.
