摘要： In one embodiment, the present invention relates to a method to operate an internal combustion engine equipped with an Electronic Control Unit (ECU) with memory, an exhaust system including a Diesel Oxidation Catalyst (DOC), a Diesel Particulate Filter (DPF), upstream of a Selective Catalyst Reducer (SCR). A doser is in the DPF and actuated by commands from the ECU. The method includes sensors at the DPF and SCR electronically connected to the ECU to transmit data signals indicative of operating conditions at the DPF and SCR. The method includes sensing the temperature at an outlet of the DPF and an inlet at the SCR determining whether that temperature is at least a predetermined temperature for a predetermined period of time, and introducing heat to the SCR to raise its temperature to a predetermined level for a predetermined period of time, such as light off temperature, to operate more efficiently. Heat may be introduced in the exhaust stream by engine thermal management strategies as well.
