摘要
Disclosed is a method for reducing the rate of exhaust heat loss. The method comprises the steps of determining whether an engine is motoring and determining whether a diesel particulate filter needs to be regenerated. Further, the method comprises the step of closing an air throttle to a substantially closed position for reducing the flow of intake gas into the engine if the diesel particulate filter needs to be regenerated and if the engine is motoring. Further yet, the method comprises the step of opening the EGR valve to an at least partially open position for allowing the exhaust gas to recirculate through the engine if the diesel particulate filter needs to be regenerated and if the engine is motoring.
