Abstract
A fuel injection system for internal combustion engines in which fuel is metered out on the basis of the relative rotation of an air flow rate metering flap in the induction tube to a location upstream of the throttle valve. In order to prevent fuel condensation on the throttle valve during engine idling, the idling fuel quantity is delivered to a separate point in the induction tube lying downstream of the throttle valve.
