To design diesel engines adapted to future exhaust gas regulations, it is important to develop a driving mode simulator to simulate vehicle performance and exhaust emissions, including aftertreatment systems. A driving mode simulator with simple and high-speed calculation characteristics was developed with a diesel combustion model based on the Hiroyasu model. In this investigation, to expand the model for premixed compression ignition engines, the Schreiber's reduced kinetic model for ignition and combustion with the characteristic mixing time model was introduced. As a result it was possible to simulate the low-temperature oxidation and main combustion for several engine operating conditions.
