In
recent years, much research has been performed in order to decrease
fuel consumption, noise, and exhaust emission levels in internal combustion
engines. In this study, the effects of excess air coefficient on performance
and exhaust emissions (CO, CO2) of an HCCI engine fueled
with primary reference fuel (PRF) were investigated for different
intake air pressure and temperature values. The simulation studies
were performed by using SRM Suite software. The chemical kinetic mechanism,
which contains 138 species and 633 reactions that are embedded into
the program, was used to simulate the combustion of the PRF fuel during
the combustion simulations. The analysis covers the full cycle and
provides data about induction, compression, combustion, expansion,
and exhaust. The exhaust emissions, cylinder pressure, and heat release
rate results were compared with the experimental data. The zero-dimensional
software (SRM Suite) gives quite reasonable results compared with
the experimental data, and it has advantages such as the shorter solution
time and the unlimited chemical kinetic mechanism compared with the
three-dimensional combustion simulation software.
