FIELD: mechanical engineering; internal combustion engines.
SUBSTANCE: according to invention in end face of intake manifold of internal combustion engine ring slot is made around each outlet hole forming inner and out walls. At least one hole is made in outer wall and at least two tangential holes are made in inner wall which are preferably arranged symmetrically relative to longitudinal axis of outlet hole and equally spaced.
EFFECT: increased power output of engine, reduced fuel consumption owing to provision of complete combustion of fuel, and reduced toxicity of exhaust gases.
