FIELD: internal combustion engines.
SUBSTANCE: invention can be used in the internal combustion engines. Proposed method consists in response to increase in vacuum demand, hollow throttle valve is displaced with perforated edge to a more closed position. In response to the transfer of the hollow throttle valve to the more closed position, the working parameter of the engine is controlled, and a vacuum is created due to the flow of sucked air flowing around the perforated edge of the hollow throttle valve. Invention discloses version of method of creating vacuum with throttle valve and versions of systems for creation of vacuum with throttle valve.
EFFECT: technical result consists in simplification of control of intensity of common air flow entering engine intake manifold.
