The article presents the results of conceptual and research works of an internal combustion engine adapted for hydrogen supply. The engine was equipped with a direct injection of hydrogen into the combustion chamber, allowing the control of the heat release rate. The developed concept of the power supply system and the fuel injection strategy were presented. Initial results of bench tests were also presented.
The article presents an analysis of phenomena affecting the formation of nitrogen oxides during the combustion of a hydrogen-air mixture in a spark-ignition engine. Studies have been carried out to determine the strategy of creating and burning a hydrogen-air mixture that guarantees a low concentration of nitrogen oxides. This strategy limits the synthesis of nitrogen with atmospheric oxygen during engine operation.
