  • Systems and methods for desulfation of an oxidation catalyst for dual fuel engines
    Patent number: 10100689
    Abstract: A system and method are disclosed for desulfating an oxidation catalyst in an aftertreatment system of a multifuel internal combustion engine. The oxidation catalyst can be desulfated in response to one or more desulfation triggering events. The desulfation process includes providing hydrocarbons from one or all of the multiple fuel sources to an upstream oxidation catalyst. The hydrocarbons react with the exhaust gas within the upstream oxidation catalyst to deplete oxygen in the exhaust flow to thereby reduce the desulfation temperature of the oxidation catalyst while elevating a temperature of the exhaust gas to a desulfation temperature range.
