Abstract
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.
