FIELD: machine building.
SUBSTANCE: invention relates to the engine building. Intake system comprises cylinder (30) with inlet channel, projection system (148) located in hole on lower wall of inlet channel closest to cylinder (30). Ledge system (148) comprises tongue arranged to move inside spring-loaded sealing case. Spring-loaded sealing housing is attached to area of lower wall forming said hole. Controller (12) stores long-term instructions in memory, made with possibility, during their execution, to provide activation of actuator by controller (12) for movement of lug of projection system outward from spring-loaded sealing housing through specified hole on lower wall of inlet path in compliance with operating mode. Also versions of intake system are disclosed.
EFFECT: technical result consists in improvement of fuel economy.
