An exhaust purification device comprising an opening/closing control valve that controls the inflow of exhaust gas into the bypass passage .

Claims

[Claims for Utility Model Registration] 1. An exhaust gas temperature detector is arranged in the exhaust passage of the engine, and the exhaust passage is branched into a main exhaust passage and a bypass passage, and the main exhaust passage has the above-mentioned An opening/closing control valve operated by a signal from a detector is provided, an adsorbent for adsorbing malodorous components in exhaust gas is arranged in the bypass passage, and the opening/closing control valve is operated when the detector detects that the temperature of the exhaust gas is below a predetermined value. An exhaust gas purification device characterized in that a control valve is closed, and when a predetermined value or more is detected, the opening/closing control valve is opened. 2. The exhaust gas purification device according to claim 1, wherein the on-off valve is arranged so that the bypass passage is closed when the on-off valve is opened. 3. The exhaust purification device according to claim 1, wherein a catalyst located downstream of the adsorbent is provided in the bypass passage. 4. The exhaust gas purification device according to claim 1, wherein a catalyst is disposed in the exhaust passage downstream of the confluence of the main exhaust passage and the bypass passage. 5. The exhaust purification device according to claim 1, wherein a filter for removing particulates in exhaust gas is disposed in the exhaust passage upstream of the branching point between the main exhaust passage and the bypass passage.
