  • System for controlling triggering of adsorber regeneration
    Patent number: 7707826
    Abstract: A system, method, and software for triggering regeneration of an adsorber connected with a flow of exhaust from an engine. An exhaust sulfur flow rate module estimates a sulfur accumulation rate associated with an adsorber as a function of a flow of fuel. A sulfur removal rate module estimates a sulfur removal rate associated with the adsorber. An accumulated sulfur loading module includes a counter the value of which is increased as a function of the sulfur accumulation rate and decreased as a function of the sulfur removal rate. A combustion manager module controls an engine to regenerate the adsorber once the counter reaches an upper threshold value.

  • Optimized desulfation trigger control for an adsorber
    Patent number: 7533523
    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.
