A fuel delivery system for an internal combustion engine having an intake air metering device, leading to individual combustion chambers several fuel injection valves, each of which is assigned to one combustion chamber, and a central fuel vaporizer to which fuel can be supplied by a fuel metering device. To reduce pollutant emissions during the warm-up phase of the internal combustion engine after start-up, fuel vapor generated in the fuel vaporizer can be added to the intake air for the combustion chambers downstream from the intake air metering device.

[ What is claimed is:] [1.] A fuel delivery system for an internal combustion engine, comprising:an intake air metering device;at least one intake tube disposed downstream of the intake air metering device, the at least one intake tube transporting intake air to a respective combustion chamber associated with each of the at least one intake tube, each combustion chamber being associated with a fuel injection valve for spray-discharging fuel to each combustion chamber through a first fuel passage;a central fuel vaporizer connected to the at least one intake tube through a second fuel passage that is different than the first fuel passage and generating a fuel vapor that is provided to the at least one intake tube through the second fuel passage, the central fuel vaporizer receiving fuel from a fuel metering system; andwherein the fuel vapor generated by the central fuel vaporizer is generated in the central fuel vaporizer independently of the fuel spray-discharged by the fuel injection valve for each combustion chamber and is added to the intake air for each combustion chamber in a respective one of the at least one intake tube downstream from the intake air metering device, and wherein the fuel vapor generated by the central fuel vaporizer is fed into the spray-discharged fuel generated by the fuel injection valve.
