In order to simulate the combustion system work process for an internal combustion engine accurately,the paper simulates the combustion process which based on the modified 4JB1 engine and used the KIVA-3V software. Variables such as cylinder pressure, cylinder temperature, NOX and SOOT emission are predicted and analyzed by using single injection strategy.It was found that the production of NOX begins from the moderate burning period, reaches a peak quickly and keep constant. The production of SOOT is mainly in the late of fast burning period to the moderate burning period and most of the SOOT is oxidized.

A model for the thermal part of an ionization signal is presented that connects the ionization current to cylinder pressure and temperature in a spark ignited internal combustion engine. One strength of the model is that, after calibration, it has only two free parameters: burn angle and initial kernel temperature. By fitting the model to a measured ionization signal, it is possible to estimate both cylinder pressure and temperature, where the pressure is estimated with good accuracy. The model approach is validated on engine data. Cylinder pressure and ionization current data were collected on a Saab four-cylinder spark ignited engine for a variation in ignition timing and air-fuel ratio. The main result is that the parametrized ionization current model can be used to estimating combustion properties as pressure, temperature, and content of nitric oxides based on measured ionization currents. The current status of the model is suitable for off-line analysis of ionization currents and cylinder pressure. This ionization current model not only describes the connection between the ionization current and the combustion process, but also offers new possibilities for engine management system to control the internal combustion engine.
