ABSTRACT:
A fuel injection system for a mixture-compressing internal combustion engine has separate ignition and continuous injection into the engine inlet duct which includes an adjustable throttle butterfly valve and a baffle flap pivoted at the side of the duct under the effect of the flow through the duct acting in opposition to a return force. The flap is coupled to a damper blade, and also to a coaxial rotary control member of a fuel metering valve, the latter comprising a control cylinder and a control piston rotating inside and in relation to the cylinder, and metering a quantity of fuel to one or more injector nozzles in proportion to the air current quantity. The control cylinder being stationary and mounted alongside the baffle flap outside the inlet duct, and the rotary control piston being connected outside the control cylinder adjacent one end to the baffle flap, and adjacent the other end to the damper blade, so as to rotate with the flap and the blade.
