A review of hydrogen/diesel fuel blends in internal combustion engines

Abstract

A hydrogen fuelled internal combustion engine has great advantage on exhaust emission in comparison with a conventional engine from fossil fuel. Despite diesel engines are indispensable for the transport sector, the decreasing emission regulations limit values in recent years' force researches to find other alternative fuels to use in addition or straight without major engines modifications. A comprehensive review of the recent research activities on the use of hydrogen/diesel fuel blends is documented. Also the challenges and perspectives and main limitations are analysed in this paper.
