- Abstract
- The article provides an overview of technologies and technical means for supplying a hydrogen-based fuel mixture to automotive internal combustion engines (ICE). Systems with hydrogen injection into the combustion chamber of an internal combustion engine and into the intake manifold, multi-fuel systems with synthesis gas based on hydrogen, balloon-type systems and with built-in hydrogen generators (electrolyzers), systems with technical means for neutralizing exhaust gases released during the combustion of fuel mixtures hydrogen-based systems, as well as systems containing technical means to ensure the safety of the storage process, hydrogen supply and prevent the negative consequences of leaks, fires, explosions, etc. The results of existing research and development are implemented mainly in experimental installations that allow one to study individual processes: combustion of hydrogen-based fuel with the determination of the optimal composition of the fuel mixture and the mass fraction of hydrogen, in particular, the optimal parameters of hydrogen supply; release and neutralization of exhaust gases with the determination of the amount of harmful emissions and the development of measures to reduce them to maximum permissible concentrations (MPC), etc. These studies ultimately make it possible to assess the power, fuel and economic, environmental and other parameters of the internal combustion engine. Nevertheless, it was noted that the systems for supplying hydrogen to the internal combustion engine are currently losing their relevance in view of the global trend of transition from internal combustion engines to an automated electric drive with power plants based on alternative energy sources. For further research, a review and analysis of work on the creation of power plants for transport and transport-technological facilities based on hydrogen is planned.
