Flow divider device for air manifolds adapted to generate turbulent flows in combustion chambers

A device (12) for air/fuel manifolds (11) adapted to generate turbulent flows in combustion chambers. The device (12) comprises a plurality of runners (16) each of which internally comprises a longitudinal baffle (17) adapted to form two channels (18, 19) each having a respective flow of air/fuel mixture to the combustion chamber. Moreover, in one channel (18) is housed a throttle (20) having, in its fully closed position, an aureole (24) which extends along the whole perimeter of the throttle (20). The longitudinal baffle (17) has a port (23) for communication between the two channels (18, 19), whereas a jet (GET) of fuel generated by an injector (22) is targeted on the port (23) for communication between the two channels (18, 19).
