Abstract: 

This paper brings out the performance of the “hydrogen engine”. The onset of increase in the automobile led to exploitation of fossil fuels, which result in environmental problems such as pollution and greenhouse effect. Due to constant increase in depletion of fossil fuels and its consequent effect on the environment and ecology. The alternative fuel research becomes the main purpose now a days. Hydrogen fuel is coming to the front of interest of experts from whole of the world. This paper deals with the use of hydrogen as an energy source for mobile machines or engines.

A hydrogen engine vehicle is an automobile, which uses hydrogen as its primary source of power. There is no change in the operation of vehicle; it works like a traditional gasoline engine. The specialized fuel injection system is to be needed. Hydrogen is obtained by separating the hydrogen from oxygen with in the water by using electrolysis process. However it needs energy like electricity. The power and torque developed by hydrogen engine is same as that of gasoline engines.
