A Quasi-Dimensional SI Burn Rate Model for Carbon-Neutral Fuels

Sebastian Hann describes the development of a quasi-dimensional burn rate model that enables the prediction of a fuel variation, without the need for a recalibration of the model. The model is valid for spark-ignition combustion engines powered by conventional and carbon-neutral fuels.
Its high predictive ability was achieved by modeling the fuel-dependent laminar flame speed based on reaction kinetics calculations. In addition, the author discards a fuel influence on flame wrinkling by performing an engine measurement data analysis. He investigates the fuel influence on engine knock and models it via ignition delay times obtained from reaction kinetics calculations.
