ABSTRACT:
A unit intended to supply gasoline and air mixture to an internal combustion engine in special operation conditions, such as the operation at the minimum speed, the start period, the operation as motor-brake and/or the acceleration, comprises a main air intake in the form of a venturi tube defining a restricted cross section, intended to be connected to an intake conduit downstream the carburetor shutter, a jet for the supply in the operation at the minimum speed, which has an own air intake and opens in the restricted cross section of the main air intake, a jet for the operation in the start period, which has an own air intake and opens in the main air intake dowstream the restricted cross section thereof, and two solenoid valves arranged to independently cut off, when activated, the one or the other jet or both. Both the jet for supply during the operation at the minimum speed and the jet for supply during the start period comprise each a vertical tube which plunges in the constant level bowl of the carburetor and is provided with a fuel nozzle, and this verical tube is internally subdivided, on a part of its height, by a dividing wall which defines a section of the tube which communicates with the own air intake to the jet.
