Analysis of the influence of substitute fuels on properties operating conditions of military hybrid drive systems

The energy density of chemical batteries makes it difficult to rely solely on cheap and eco-friendly electricity for power in many applications, such as airplanes, long-distance trains, ocean vessels, and heavy equipment. Limited charging infrastructure and power generation capacity are also problematic. However, hybrid powertrains provide a solution by combining electric and internal combustion engines to achieve better fuel economy and similar operational characteristics to traditional engines. Hybrid systems can also use alternative hydrocarbon fuels , with all advantages of conventional engines. This study aimed to determine the impact of alternative fuels on the performance of a hybrid drive system for a military wheeled platform developed for operation in urban areas. The experiment found that substitute fuels, such as, F-34, and Jet A-1, were compatible but could result in increased fuel consumption, decreased energy efficiency, and negative environmental impacts due to higher exhaust emissions.
