Vehicles with internal combustion engines play a significant role in many fields, including the space industry. Vehicles with internal combustion engines are used in the production, pre-launch preparation of spaceships and spaceship cargo transportation. The use of alternative fuels for internal combustion engines of transport means is made relevant with the continuous reduction of hydrocarbon fuel reserves. One of the most promising type of alternative fuel is biofuel. This paper presents the results of the calculated analysis of the characteristics of the combustion process of biodiesel fuel with palm oil and hydrogen peroxide additives and the influence of the additives on the combustion process and the ignition-delay period. The calculated analysis performed has shown the effectiveness of the use hydrogen peroxide as an additive in for the selected biofuel to reduce the ignition-delay period and thus increased the power and economical parameters of the engine. © 2020, Univelt Inc.
