REVIEW ON COMBUSTION AND PERFORMANCE ANALYSIS OF REACTIVITY CONTROLLED COMPRESSION IGNITION (RCCI) ENGINE
Keywords:

This paper describes recent progress to improve the fuel efficiency of diesel or CI engines through advanced
combustion and fuel research. A dual-fuel Reactivity Controlled Compression Ignition (RCCI) combustion strategy will
address these issues due to the existence of precise means for controlling the heat release rate and combustion phasing. In
the RCCI strategy two fuels with different reactivity (auto-ignition characteristics, e.g., gasoline and diesel) are blended
inside the combustion chamber. Combustion phasing is controlled by the relative ratios of these two fuels and the combustion
duration is controlled by the local equivalence ratio gradient between the two fuels. This review focuses on development of
RCCI engine combustion model and understanding the effects of key parameters controlling RCCI engine combustion.
