| Abstract(E) | The promotion of mixing between hydrogen and air is effective for improvement of thermal efficiency of hydrogen direct injection engines. This study proposed an engine system with air direct-injection in order to improve mixing characteristics, and implemented zero-dimensional simulation to evaluate the thermal efficiency of proposed engine. Moreover, CFD analysis of hydrogen jets and air jets into a constant-volume container was conducted in order to investigate the effects of air injection to the mixture formation. |
