“…In this case, as a characteristic of energy efficiency using the ratio of fuel consump-tion rate to engine power is brake-specific fuel consumption. This approach is based on the fact that the main losses of installations fall on the internal combustion engine [5]. The second group of studies is devoted to power plant as a whole, in some cases considering the energy performance of system components.…”

The paper presents a new approach to energy indicator determination, such as specific fuel consumption and energy efficiency of the power plant. The essence of the new method is to determine the instantaneous power of the installation with subsequent data processing. The use of this method allows establishing the dependence of specific energy indicators on the generating unit load levels. The established distribution allows defining optimum parameters of experimental setup and consumption at various loading levels. The highest specific energy consumption of fuel is observed (1189–1297 g /(kW h) and 962–1147 g / / kW h)) at the lowest and the highest load for different fuels. Experimental data show that fuel without ethanol impurities can generate more electricity, which should be used at higher demand.

The use of generators at different load levels allows you to use part of the rated power of the engines, by reducing the speed of the internal combustion engine, thus reducing fuel consumption and increase the overall efficiency of the system as a whole. However, it should be noted that the optimal operation of the internal combustion engine at fixed gas distribution parameters is possible only at a certain engine speed. Reducing the engine speed leads to a deterioration of the filling of the fuel-air mixture and the release of exhaust gases from the engine, accompanied by the intake of exhaust gases into the intake manifold and the emission of part of the fuel mixture into the exhaust pipe. The paper presents the results of the study of generator parameters and the general concept of creating an autonomous power supply control system based on an internal combustion engine in order to reduce the specific indicators of electricity generation. The expediency of regulating the power level of an internal combustion engine has been experimentally proved. To achieve this goal, it is proposed to adjust the opening and closing angles of the internal combustion engine with a solenoid valve. The use of this system allows to reduce the specific costs by more than 4 times when generating electricity with low generator load. Based on the phase distribution diagram of the internal combustion engine, the dependence of the change of the opening and closing angles of the inlet and outlet valves on the power of the autonomous energy source is proposed.
