Hydrogen-fueled internal combustion engine: A review of technical feasibility

Practically, it is impossible to substitute internal combustion engine which has become an integral part of the transportation and agriculture sectors. The fossil fuel resources are limited and depleting at very fast. Therefore, in future our energy system will have to be renewable and sustainable, efficient and cost effective, convenient and safe. In order to cope with the environmental concerned there have been many studies and trials on various types of automobile engines. As indicated by recent studies hydrogen fuelled vehicles appeared to be more eco-friendly and available in abundance. However the problems associated with hydrogen fuelled engine are pre-ignition, backfiring, rapid rate of pressure rise and knocking which need to be overcome so that hydrogen fuelled driven engine could be further develop and commercialize. This review paper is basically deliberating the various problems associated with the use of hydrogen driven engines in automobile sectors and suggestions to make this technology commercially viable.
