Abstract

Content: The paper evaluates different strategies of dual fuel (DF) operation in search of a solution that enables DF at low load. The strategies that were explored are conventional DF with increased intake temperature, split injection, and reactivity controlled compression ignition (RCCI) combustion. The RCCI operation enabled DF operation at higher natural gas mass fractions, with higher efficiency, and lower THC, CO and NO_X emissions than in DF operation, while the efficiency of normal diesel operation (NDO) remained highest. If CO₂ emission or cost effectiveness is used as a measure of performance then RCCI provided better performance than NDO as well.
