Modeling of compression-ignition combustion process with multi-zone spray model and detailed chemical kinetic mechanism was performed to analyse the combustion characteristics and performances of a diesel engine. In the modeling, the combustion chamber is divided into a single air zone and several fuel-spray zones. Spray penetration is obtained by an empirical formula and air entrainment into the fuel-spray zones is determined by momentum conservation. Each zone has its own histories of temperature, pressure and species, based on the energy conservation, ideal gas laws, and chemical reactions. The use of detailed chemical kinetic mechanism allows to accurately model the combustion process throughout the cycle. In further study not included in this paper, optimization between calculation time and accuracy can be found by setting the appropriate number of cells. It is also expected that the prediction of NOx formation is possible by additional consideration of NOx formation mechanism.
