1. a kind of pressure charging system, possesses:

  • First booster, it has the first compressor for being used for compressing the air supplied to engine;

    Second booster, it, which has, is used to further compress by the second compressor of the air of first compressor compresses;

    Control device, it is used to control first booster and second booster,The pressure charging system is characterised by,At least one party of first booster or second booster also has motor, and the motor is described for drivingFirst compressor or second compressor,At least one party of first booster or second booster also has:

    Turbine, is consisted of by from the hairThe exhaust rotation driving of motivation;

    Nozzle vane, consists of the flow path area for the exhaust that regulation is flowed into the turbine,The control device is included:

    Motor control part, is consisted of, and is less than first in the charge volume for the battery to the powering electric motorsDuring threshold value, the higher limit of the output order value of the motor is set to that the charge volume than the battery is first thresholdIt is low during the value above, or the motor is switched into regeneration operating;

    Blade control unit, it is when the charge volume of the battery is less than the first threshold, with the motor control partControl to the motor, controls the aperture of the nozzle vane so that the flow path area diminishes.
