Conversion of a diesel internal combustion engine to hydrogen power

The aim of this study was to devise and design the conversion of a compression-ignition engine, to a spark-ignition engine powered by hydrogen. The second objective of the present study is to expand research into the use of hydrogen in heavy-duty engines used in rail vehicles, ships and trucks. The engine would be used to measure exhaust emissions with hydrogen fuel, noise levels, and engine performance in a controlled setting. The initial section of the article comprises an examination of the extant literature pertaining to the historical and contemporary limitations imposed on the emission of greenhouse gases in railway and truck transport operations. The subsequent section delineates the challenges associated with the application of hydrogen in combustion engines. The third chapter details the complex process of converting, a diesel compression-ignition engine into a spark-ignition engine fuelled by a hydrogen–air mixture, and the necessary modifications to engine subsystems, including fueling, ignition and control. The final chapter presents the possibilities of using the converted engine in research and development of future transport.
