The demand for energy grows along with the number of studies in the field of alternative energy. Clean energy has been the goal of numerous studies and it has been encouraged, seen by the gradual migration from conventional to hybrid or purely electric vehicles. Although clean energy is desirable, we continue to rely on traditional fuel.

The dual fuel reactivity controlled compression ignition (RCCI) concept has been successfully demonstrated to be a promising, more controllable, high efficiency, and cleaner combustion mode. A multidimensional computational fluid dynamics (CFD) code coupled with detailed chemistry, KIVA-CHEMKIN, was applied to develop a strategy for phasing control ...

Journal of Engineering for Gas Turbines and Power, 2011
The present study uses numerical simulations to explore the use of hydrated (wet) ethanol for reactivity controlled compression ignition (RCCI) operation in a heavy duty diesel engine. RCCI uses in-cylinder blending of a low reactivity fuel with a high reactivity fuel and has demonstrated significant fuel efficiency and emissions benefits using a ...

Abstract An improved multi-dimensional model coupled with detailed chemical kinetics mechanism was applied to investigate the combustion and emission characteristics of a methanol/diesel reactivity controlled compression ignition (RCCI) engine. The fuel was supplied separately by directly injecting diesel fuel into cylinder well before top dead ...

Nowadays, due to the environmental problems caused by pollution and high fossil fuels prices, the study on the internal combustion engines have attracted many researchers. Investigations show that low-temperature combustion engines play a very effective role in increasing efficiency and reducing emissions.

Abstract In an RCCI (reactivity controlled compression ignition) engine, the double injection strategy is a technical tool to control its combustion process. In this study, the effects of two key injection parameters, namely dwell and split fraction, are numerically investigated in a gasoline and biodiesel fueled RCCI engine.

Abstract Reactivity controlled compression ignition (RCCI) combustion has been shown to yield improved performance over conventional diesel combustion (CDC) in terms of efficiency and emissions at mid load conditions. However, operation under high load and low load conditions is a major challenge with RCCI combustion.
