| Summary: | Reactivity Controlled Compression Ignition (RCCI) is an efficient dual-fuel engine combustion technology that can offer low
emission level in internal combustion engine technology. RCCI technology works by generating reactivity stratification in
the cylinder with two fuels of different cetane numbers. To accomplish reactivity stratification, the fuel with lower reactivity
is premixed with air before charging into the combustion chamber. The fuel with higher reactivity is injected subsequently
using a direct injector. By properly manipulating the fuel ratio and the injection timing, one is able to regulate the combustion
phasing and lessen the rates of pressure rise and heat release thanks to the reactivity gradient. Meanwhile, factors such
as compression ratio (CR) and piston bowl geometry could influence the characteristics of RCCI. Evaporation, mixing, and
combustion processes are dependent on the fuel type. In this paper, recent progress to improve the combustion processes
with several aspects of changing of RCCI engine parameter are reviewed, such as management strategy, compression ratio,
EGR rate, and bowl geometry. |
