The internal combustion engine has played an important role in the transport industry with outstanding advantages in power generation, although the increasing pressures of fuel use and environmental pollution from the these engines are big problem. Moreover, increasingly stringent emissions targets and the rapid depletion of oil resources have prompted researchers to study the use of alternative fuels for diesel engines. Hydrogen is one of the best alternatives to traditional fuels. Hydrogen has its benefits and limitations in its use as an alternative fuel in transportation engines. Hydrogen is the most abundant element in the universe and exists mainly as a compound with other elements. Hydrogen has long been viewed as a desirable fuel for internal combustion engines. Unlike fossil fuels, these are non-polluting fuels, renewable and can be produced from endless water. On the other hand, one of the most effective ways to improve combustion efficiency on existing engines without much change in engine structure is to add a small amount of hydrogen gas or hydrogen-rich gas to the engine. This paper briefly presents the outstanding properties of hydrogen fuels that affirm their applicability in internal combustion engines. Furthermore, the evaluation of hydrogen fuel using solutions on SI and CI engines is also presented to clarify the engine characteristics and emissions when using this fuel.
