ABSTRACT:
A fuel injection system for a mixture compressing spark ignition internal combustion engine includes means for injection of fuel into the air intake of the engine. A fuel metering valve dispenses to one or more injection jets a quantity of fuel related to the quantity of air flowing through the intake. An adjustable throttle valve is in the air intake as well as an air flow measuring element which is movable against a restoring force in accordance with the quantity of air flowing through the intake. The measuring element is arranged to actuate a control element of the fuel metering valve. A damping device having a damping element connected to the measuring element is movable to displace fluid between two damping chambers through a throttling passage. One damping chamber is connected to a fuel pump which delivers fuel to the metering valve while the second damping chamber is connected to a discharge port through a thermally controlled outlet valve. A metering trap chamber downstream of the outlet valve is provided with means for emptying the trap chamber after operation.
