The paper considers the possibility of using hydrogen as an additive to the main type of fuel in special purpose vehicles with a diesel-powered internal combustion engine (ICE) in order to improve environmental safety. There has been developed a mathematical model for describing the processes of combined cycles of the internal combustion engine operating on diesel fuel and hydrogen additives. Theoretical methods for investigating the technical parameters of internal combustion engines at using hydrogen additives are presented. Based on theoretical relationships and data, the environmental safety of special purpose vehicles on the territory of St. Petersburg can be improved.
