ABSTRACT:
A fuel supply assembly for a gasoline internal combustion engine in which the amount of fuel supplied is controlled by an electromagnetic injection valve which in turn is controlled by an electronic controller subjected to operating parameters. The assembly comprises a fuel metering device and a vane pump in which is supplied a branch stream of air tapped from an inlet duct upstream of the throttle valve. The fuel is introduced into the pump chamber downstream of the air and both the fuel and air are supplied to the pump chamber substantially tangentially to be mixed for the first time in the pump chamber.
