چکیده

Abstract The European Green Deal for halving greenhouse gases emissions by 2030, compared to those of 1990s, and the resulting conversion in road transport from 2035 imply need automotive field. Hydrogen-fueled internal combustion engines show a good potential satisfy transition towards carbon neutrality. In particular, direct injection hydrogen spark-ignited have great efficiency potentialities, nonetheless design optimization systems needs extensive analysis evaluation hydrogen-air mixing processes under different engine operating conditions. Transient simulations gas-exchange process fuel are fully described within this paper two commercial CFD codes namely, AVL-Fire Ansys-Fluent. Both use finite-volume approach discretize governing equations. Numerical results been against experimental data provided Argonne National Laboratories terms contours mole-fractions velocity-field vectors, applying laser-based techniques on an optically accessible, single-cylinder engine.
