FIELD: mechanical engineering; engine manufacture. SUBSTANCE: method involves two-stage variation in volume of cavity connected to its intake manifold at rate proportional to engine speed; minimal volume of cavity is adjusted with admission valve held open for time Δt = (1,0-0,7)to, where to is time interval within which cylinder intake element is held open. EFFECT: improved efficiency of engine supercharging. 2 cl, 5 dwg
