Review of Hydrogen as a Fuel in IC Engines

The Internal Combustion Engines are used widely in present generation. The internal combustion engine is an engine in which the combustion of a fuel occurs with an oxidizer in a combustion chamber that is an integral part of the working fluid flow circuit. Hydrogen plays an important role for energy diversity. It stores energy from different local sources which includes clean nuclear, coal, and various available renewables for use in many applications. Vehicles operating on hydrogen can dramatically reduce our nations dependence on oil and significantly reduce tailpipe emissions. Hydrogen offers a potential means to store and deliver energy from locally available resourceswhile reducing our nations economy on fossil fuels. This paper presents the use of Hydrogen as an alternative fuel in IC engines and relevant facts and scope for future work. This paper also focuses on different researches and existing method of hydrogen generation system for producing hydrogen and injecting the hydrogen as a fuel supplement into the air intake of carburettor. Detailed review of the work in combustion and emission characteristics was done. The scope of this paper is to perform a detailed review of the use of Hydrogen in IC engines. The data about production, storage, and the effects of hydrogen on performance of engines was collected from research papers of various authors and then systematically presented here.
