First hydrogen combustion engines will most likely go into series with port-fuel injection, based on Diesel engine hardware. But it is already obvious that direct injection concepts will represent the second generation of mixture formation systems. Challenges like injection nozzle design and mixture formation for highest levels of homogeneity are already well known. Market participants are improving these kind of product properties. This paper discusses several additional opportunities aiming to increase the homogeneity index of direct injection concepts allowing in consequence for lower NOX and/or higher torque output at the borderline of an air-to-fuel ratio of approximately 2.5. The new Schaeffler Condă nozzle provides best results in terms of homogeneity using both flow patterns, Coandă and a straight jet, during the same engine working cycle. The Coandă fuel mass share can be varied by parameters like pressure ratios, needle lift and Coandă radius.
