An open-loop control module for ramping up and maintaining a temperature value of an adsorber to a regeneration temperature value by controlling an air fuel ratio value of an engine to operate at an open-loop controlled variable duty cycle. A closed-loop control module is operable to take control from the open-loop control module to maintain the adsorber at the regeneration temperature value if the temperature value of the adsorber deviates from the regeneration temperature value by controlling the air fuel ratio value of the engine to operate at a closed-loop controlled variable duty cycle.

摘要： A system, method, and software for triggering regeneration of an adsorber connected with a flow of exhaust from an engine. A sulfur loading estimate module is used to generate an estimated sulfur loading value associated with an adsorber. A desulfation trigger module is used to trigger a desulfation event for the adsorber upon detection of a trigger event comprising either a cost-effective trigger event, a loading trigger event, and a forced trigger event. A combustion manager module is used to control an engine through engine management to regenerate the adsorber during the desulfation event. A interrupt module is used to interrupt the desulfation event upon detection of an interrupt event. An end desulfation module is used to stop or end the desulfation event upon detection of an end desulfation event.
