Abstract
An exhaust purification device for an engine comprises a catalytic device for purifying exhaust by using an additive, a deflecting device for allowing the exhaust to flow through and causing the exhaust to be agitated, upstream of the catalytic device, an additive injection device for injecting an additive, downstream of the deflecting device, a temperature detection device for detecting exhaust temperature, downstream of the deflecting device, and a control unit for controlling the additive injection device on the basis of the exhaust temperature detected by the temperature detection device. The temperature detection device has a temperature detection part located within a region where the exhaust having passed through the deflecting device has increased velocity.
