FIELD: internal combustion engines.
SUBSTANCE: invention relates to propulsion engineering, namely, to turbocharger supercharging pressure control. Control method of boost pressure regulator (26) includes the following steps: using controller (12) determining pressure drop on valve of supercharging pressure regulator (26) of turbocharger of engine based on pressures measured by pressure sensors (82, 84) located upstream and downstream of turbine supercharger turbine (62), respectively. Retention current is determined from fluctuations of pressure drop on pressure control valve (26). Retention current is supplied to drive (150) of pressure control (26) of supercharge pressure, which is functionally connected to pressure control valve (26) for pressurization of pressure control valve (26) of supercharging pressure in the required position. Invention covers also control system of supercharge pressure control and version of control method of pressure control.
EFFECT: technical result consists in reduction of power consumption of the supercharger drive and reduction of heat emission in the drive.
