Hydrogen Storage and Materials

The limited quantities of oil reserves and the exhaust emissions from IC engines have become a threat to the existence of IC engines.One of the best solutions to the problem is the use of alternative fuels.Hydrogen is an alternative fuel that is called a fuel of the future.A disadvantage of hydrogen is its high combustion speed.Experimental results were used for the determination of inputs for numerical analysis.The numerical analysis is performed for a 3D model of the engine in order to determine the working parameters of the engine (pressure and temperature).The main goal of this study is to investigate a possibility of modifying the diesel engine so that it can run on hydrogen.It was found that in such an engine the greatest loads occur in the combustion chamber; thus, the vital parts of the engine are protected.Therefore, a mechanical analysis of the combustion chamber was performed (calculation of stresses and deformations).The obtained results are encouraging because they indicate that by applying the presented solution a much cheaper technology than the modern diesel engine systems is made possible.
