FIELD: engines and pumps. ^ SUBSTANCE: ICE specific fuel consumption is minimised by control using feedback with transmission elements and consists in power recuperation in vehicle incorporating ICE 3, AC generator 5, rectifier 7, controlled power accumulator 10 and traction motor 13. With braking pedal depressed or motor shaft rpm exceeding electromagnetic field revolution frequency, ICE is switched over into reduced rpm conditions. Traction motor 13 is switched over to generator conditions to charge electric power accumulator 13. With running speed and accumulator 10 charge current reducing, signal is fed in accumulator control system 10.2 to change pattern of connecting single elements. Voltage fed to each elements of accumulator 10 is increased. Accumulator charge current is increased. Proposed fuel consumption minimising device comprises traction motor shaft rpm transducer 14, capacitor unit charge pickup 11, voltage comparators (18), power absorption comparator 9 and logical unit 20, fuel feed cutoff control unit 17, controller power accumulator 10, braking pedal position transducer and three-level comparator 19. ^ EFFECT: optimum use of electric power accumulators, reduced costs and specific fuel consumption. ^ 2 cl, 3 dwg |
