Exhausted particulate treatment device for an engine, engine, computer program product, computer-readable storage medium and exhausted particulate treatment method for an engine

Exhausted particulate trapping means 12 is disposed in an exhaust passage of the engine, for trapping exhausted particulate in exhaust gas. Regenerating means is provided for burning out the particulate trapped in the exhausted particulate trapping means 12 under a condition. Accelerating condition detecting means is provided for detecting the accelerating condition of the engine. When the accelerating condition detecting means detects the accelerating condition while the regenerating means is in its burning-out operation of the particulate, the temperature of the exhaust gas flowing into the exhausted particulate trapping means is raised from the exhaust-gas temperature attained while the regenerating means is out of its burning-out operation. The exhaust-gas temperature flowing into the exhausted particulate trapping means 12 is raised when the engine accelerates while the particulate is being burned out, so as to suppress the temperature-drop in the exhausted particulate trapping means 12, thereby reliably burning out the particulate.
