Growing environmental concerns mandate ever more stringent fuel economy
and emission regulations to the automotive industry, which require synergy of
advanced in-cylinder combustion and aftertreatment. Therefore, it is important to
develop new strategies such as direct injection lean burn combustion in order to dras-
tically reduce in-cylinder pollutant formation and fuel consumption. To achieve this
goal more effectively, it is necessary to develop a more comprehensive mathematical
model to accurately predict combustion and emissions in order to complement
experimental efforts to develop next-generation internal combustion (IC) engines.
The main objective of the present study is to develop a high-fidelity turbulent com-
bustion model for modern direct injection compression ignition (DICI) engines with
a wide variety of injection strategies.
Among many existing turbulent combustion models, the flamelet approach and
its derivatives has been successfully applied to many types of IC engine simulations
