  • Unit for supplying combustion air to the cylinders of an endothermic engine
    Patent number: 7117837
    Abstract: Unit for supplying combustion air to the cylinders of an endothermic engine is provided with a manifold having an air inlet orifice and a plurality of supply ducts. Each supply duct extends between a first opening communicating with the manifold and an outlet orifice, and has a second opening arranged between the first opening and the outlet orifice. The supply unit is equipped with a valve member that can move between the first opening and the second opening in order to close alternately the first opening and the second opening.
    Type: Grant

  • Flow divider device for air manifolds adapted to generate turbulent flows in combustion chambers
    Patent number: 6782872
    Abstract: A device for air/fuel manifolds adapted to generate turbulent flows in combustion chambers. The device comprises a plurality of runners each of which internally comprises a longitudinal baffle adapted to form two channels each having a respective flow of air/fuel mixture to the combustion chamber. Moreover, in one channel is housed a throttle having, in its fully closed position, an aureole which extends along the whole perimeter of the throttle. The longitudinal baffle has a port for communication between the two channels, whereas a jet of fuel generated by an injector is targeted on the port for communication between the two channels.
