Research and development of hydrogen fuelled engines in China

The present paper introduces the role of vehicles in the context of Chinese economy, Chinese energy security, Chinese environment and the sustainable development of China; expounds that hydrogen is the promising alternative fuel for vehicles in China; and points that developing hydrogen fuelled engine vehicle is inevitable for the further development of Chinese vehicle industry. Then, the paper reviews the research and development of hydrogen fuelled engines in China, and reports the most achievements obtained by Chinese researchers in the field of the hydrogen fuelled engines which involve hydrogen-enriched gasoline engine, hydrogen-enriched diesel engine, hydrogen-(compressed) natural gas dual (HNG/HCNG) fuel engine, and pure hydrogen internal combustion engine (H₂ICE).
