FIELD: internal combustion engines.
SUBSTANCE: invention can be used in the internal combustion engines. System (50) of the engine contains rotary inlet channel (204), circumscribing at least part of rod (206) of intake valve (18) connected to cylinder (16). Rotary inlet channel (204) has first curved section (220) extending inward toward axis of rotation (224) of rotary inlet channel (204) or out to the side opposite to axis of rotation (224). Drive (230) of the inlet channel is connected to rotary inlet channel (204) and is configured to rotate rotary inlet channel (204) around axis of rotation (224) depending on the engine operating conditions. Engine system variant and a method for controlling an engine system is disclosed.
EFFECT: technical result is to provide instability of the air flow around the head of the inlet channel to ensure the required levels of turbulence in the engine cylinder.
