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.
