Abstract

In diesel engines, the fuel mixture consisting of liquefied gas and hydrogen is prepared, and a process corresponding to the gasdiesel cycle is implemented, where methanol or diesel fuel are used as an explosive fuel, as a result of which the self-ignition delay period is reduced, and the fuel combustion duration during active combustion is reduced as well. That is, the limits of the working mixture combustion are expanded (hybrid combustion), the mixture formation process is improved, and the cycle carried out in the engine is closer to the Otto cycle, which improves the environmental and efficient indicators of diesel engine compared to the gas-diesel engine, where diesel fuel is used as an explosive fuel, which makes it possible for diesel engine to run: only on liquefied gas; only on hydrogen, only on a diesel fuel or on a combination of different fuel mixtures.
