Abstract
Apparatus for injecting fuel into the intake pipes of an internal combustion engine. The apparatus has an air channel branching off from the intake line at a point ahead of an adjustable throttle flap; a fuel metering device supplying fuel to the air channel in dependence upon engine load; and a fuel delivery pump arranged to receive a fuel-air mixture from the air channel through a narrowed constriction. The fuel pump passes the fuel-air mixture, with additional air which may be supplied thereto, to a fuel distributor which directs the mixture to the individual intake pipes of the engine.
