A quasi-dimensional model for the power cycle of a hydrogen-fuelled ICE

There is a growing body of literature as well as increased demonstration of advanced hydrogen-fuelled internal combustion engines. These engines offer the potential of high power output, outperforming gasoline engines; high efficiency, approaching or bettering diesel engines; and very low emissions well within the most strict emission standards.A simulation program is developed to calculate the pressure and temperature development in hydrogen engines. A laminar burning velocity correlation published previously by the authors is combined with a number of turbulent burning velocity models in a quasi-dimensional two-zone combustion model framework. After calibration of the combustion model for a reference condition, simulation results are compared with experimental cylinder pressure data recorded on a single cylinder hydrogen engine. Correspondence between simulation and measurement is shown for varying equivalence ratio, ignition timing and compression ratio.
