It is well-known that hydrogen energy has the characteristics of zero carbon, green, high energy, and renewable. Recently, the pure hydrogen internal combustion engine (PH-ICE) has become one of the essential directions of hydrogen energy application due to its outstanding advantages, such as no carbon emission, high efficiency, high reliability, and low pollution. So far, the PH-ICE has aroused great attention from both domestic and foreign auto companies and research institutions. This paper first introduces the latest development status of PH-ICE. Secondly, from the in-engine and out-engine technologies aspects of the PH-ICE, a comprehensive summary of its combustion performance improvement and nitrogen oxide control technology is given. Finally, the future challenges and development trends of the hydrogen ICE are discussed.

Current Progress in Automobile Design and Manufacturing

“…So far, the PH-ICE has aroused great attention from many automotive companies and research institutions. Lu and Liu et al [7] highlighted the latest development status of the PH-ICE. A comprehensive summary of the combustion performance improvement and nitrogen oxide control technology of the PH-ICE was provided, from the in-engine and outengine technologies.…”
