Abstract: Systems and methods for controlling fuelling of dual fuel internal combustion engines are disclosed. The control techniques maximize the substitution rate of gaseous fuel for the liquid fuel by determining a target fuelling amount for the liquid fuel and then regulating an actual fuelling amount of the liquid fuel in response to engine speed and power variations and by modulating the flow rate of the gaseous fuel to the engine.

Abstract: A system and method are disclosed for regenerating an oxidation catalyst used in an aftertreatment system of a multifuel internal combustion engine. According to at least one aspect of the present disclosure, recirculated exhaust gas is employed to enable recovery periods in which the engine generates oxygen-depleted exhaust to desulfate and deoxidize the oxidation catalyst. In certain embodiments, the system may include an exhaust gas recirculation system with a cooler and regulation valve to introduce exhaust gas into the engine.
