Abstract
An engine assembly includes a diesel internal combustion engine and an aftertreatment system coupled to the diesel internal combustion engine. The aftertreatment system includes a diesel oxidation catalyst coupled to the diesel internal combustion engine such that the diesel oxidation catalyst receives exhaust gases from the diesel internal combustion engine. The aftertreatment system includes a plasma generator in fluid communication with the diesel oxidation catalyst, wherein the plasma generator is upstream of the diesel oxidation catalyst and downstream of the diesel internal combustion engine, and the plasma generator is configured to generate oxidizers to at least partially oxidize hydrocarbons in the exhaust gases exiting the diesel internal combustion engine.
