FIELD: engines and pumps. ^ SUBSTANCE: invention proposes a method to control a compressor to produce compressed air with specified pressure of injection (P1) and to prevent excessive consumption of engine capacity, besides, the compressor is actuated from the engine with controlled rotation frequency, with engine windings, at which the gas temperature at the inlet (Tin), gas injection pressure at the discharge (Pd), engine rotation frequency (Vm) and temperature of engine windings (Tmw) are continuously measured during operation of the compressor. Gas temperature at the inlet (Tin) is used to determine previously specified limit value of maximum temperature of engine winding (Tmwmax). Maximum temperature of engine winding (Tmwmax) is used to specify the limit value of the engine rotation frequency (Vmmax). Maximum frequency of engine rotation (Vmmax), the specified pressure of injection (Pt) and pressure of gas injection at the discharge (Pd) are used to control the current frequency of engine rotation (Vm), keeping it below the limit value of the maximum engine rotation frequency (Vmmax). ^ EFFECT: avoidance of engine overload. ^ 1 cl, 3 dwg |
