IMPROVING THE ENERGY EFFICIENCY OF AN AUTONOMOUS SOURCE OF ELECTRIC ENERGY BY REGULATING THE GAS DISTRIBUTION OF AN INTERNAL COMBUSTION ENGINE

Abstract

The use of generators with inverters allows, depending on the load of the network, to regulate the speed ofthe internal combustion engine, thereby reducing fuel consumption and increasing the overall efficiency of thesystem as a whole. However, it should be noted that the optimal operation of the internal combustion engine ispossible at a certain engine speed. A decrease in the engine speed leads to a deterioration in the filling of the fuelairmixture and the exhaust of the engine, accompanied by an intake of exhaust gases into the intake manifold andthe ejection of part of the combustible mixture into the exhaust pipe. The paper presents the general concept ofcreating 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 an internal combustion engine that works as a sourceof mechanical energy of an autonomous source of electrical energy is proved. The use of this system allows to reduceunit costs by 2 times when generating electric energy. Based on the gas distribution diagram of the internalcombustion engine, the dependence of the change in the opening and closing angles of the intake and exhaust valveson the power of an autonomous energy source is proposed.
