Abstract
Apparatus for continuously injecting fuel into the intake pipe of an internal combustion engine. The apparatus has an air channel branching off from the intake pipe 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 delivery pump is constructed to convey fuel mixed with air even under conditions of maximum engine load. The fuel metering device has fuel exit openings which are directed toward the narrow constriction of the air channel forming the fuel delivery pump inlet.
