Hydrogen-Air Mixing Evaluation in Reciprocating Engines

    Research output: NRELTechnical Report


    This report presents the results of a computational study of fuel-air mixing in a hydrogen jet using a spark-ignited, hydrogen-fueled engine. The computational results were compared with experimental measurements being conducted at the Musashi Institute of Technology in Tokyo, Japan. The hydrogen-air mixing work was directed at understanding the extreme sensitivity of ignition to spark pluglocation and spark timing in direct-injected, hydrogen-fueled engines.
