Enhanced control of autonomous power supply process for internal combustion engine.

The use of generators with converters allows, depending on the load of the network, to regulate
the speed of the internal combustion engine, thus increasing the overall efficiency of the system and
reducing fuel consumption as a whole. However, it must be noted that the optimal operation of the
internal combustion engine is possible at a certain engine speed. A decrease in the engine speed leads
to a deterioration in the filling of the fuel-air mixture and the exhaust of the engine, beside an intake
of exhaust gases into the intake manifold and the ejection of part of the combustible mixture into the
exhaust pipe. We present in this paper the general idea of creating a control system for an
autonomous power source based on an internal combustion engine and an inverter. The expediency
of adjusting the opening and closing angles of the valves of an internal combustion engine that works
as a source of mechanical energy of an autonomous source of electrical energy is proved. By using
this system we could reduce unit costs by 2 times when generating electric energy. After seeing the
gas distribution diagram of the internal combustion engine, the dependence of the change in the
opening and closing angles of the intake and exhaust valves on the power of an autonomous energy
source is proposed.
