Application of Hydrogen and Hydrogen-containing Gases in Internal Combustion Engines

The results of studies of the influence of hydrogen and hydrogen-containing gas additives on the parameters of various types of internal combustion engines are analyzed and summarized. It made possible to identify the features of the effect on the combustion of fuel during internal combustion engine operation at partial loads. The dependences of reducing the toxicity and fuel consumption of internal combustion engine on the amount of addition of hydrogen and a hydrogen-containing gas to the air-fuel mixture were obtained. It allowed to establish quantitative effects of free hydrogen, in particular, to quantify the region of small hydrogen additives and the conditions under which hydrogen exhibits the qualities of a chemically active component of the mixture.
