This bachelor's thesis deals with the comparison of hydrogen as a fuel for an internal combustion engine against conventional fuels used in vehicles. The quantities compared are density, energy required for ignition, stoichiometric ratio, calorific value, octane number and flame propagation speed. The second part is devoted to the analysis of the implementation of hydrogen as a fuel for an internal combustion engine, both compression ignition and spark ignition. Important elements of prevention against hydrogen leakage or prevention of its concentration outside the combustion space were also described here. A well-to-wheels comparison of hydrogen production using the SMR method, and the solar electrolysis method was conducted, where the energy consumption and the production of harmful emissions were compared. Furthermore, the parameters of individual drive systems were compared, which included a conventional petrol engine, an electric drive, a hybrid drive, a biofuel burning engine, a hydrogen combustion engine, and a hydrogen fuel cell. The monitored parameters were the production of carbon dioxide and sulfur dioxide emissions, energy efficiency and range. Finally, the simulation compared a hydrogen spark ignition engine with a gasoline spark ignition engine. Gt-suite program was used. The monitored parameters were performance parameters, production of nitrogen oxide emissions, specific fuel consumption and the dependence of the course of pressure in the combustion chamber on the rotation of the crankshaft.
