FIELD: engines and pumps. ^ SUBSTANCE: air inlet 1 comprises cylindrical inlet duct 10 with axis of symmetry ö with one open end 101 and another closed end 102 to communicate with several outlets Ci on its side surface. Inlet channel open end 101 allows passage of inlet flow F along aforesaid axis of symmetry ö from open end 101 to closed end 102, the nearest to last outlet channel. Note that every outlet channel Ci communicates with engine cylinder. Note also that axis of symmetry i of every exhaust channel Ci is perpendicular to axis of symmetry ö of outlet channel 10. Note here that every outlet channel Ci mates with inlet channel 10 in mating radius Ri opposite inlet flow direction F so that said mating radius of every outlet channel Ci increases subject to inlet flow path length Li from open end 101 to axis of symmetry i of adequate outlet channel Ci to ensure equal distribution of inlet flow F in every exhaust channel Ci. ^ EFFECT: exhaust duct better capacity and distribution of rates in every duct. |
