In this thesis, a quasi-dimensional spark-ignition burn rate model for predicting the effects of changing fuel, air-fuel ratio λ, exhaust gas recirculation (EGR) and water injection was developed and validated for a wide range of boundary conditions. In the validation process, a high predictive ability was proven, especially concerning the prediction of fuel influence on engine performance. The investigated fuels were methane, CNG substitutes, methanol, ethanol, gasoline, hydrogen, methyl formate and DMC+ (65 vol−% dimethyl carbonate, 35 vol−% methyl formate). Based on the model calibration for one fuel at one λ, the change of heat release rate (HRR) with a variation of fuel and λ could be predicted, without recalibration.
