Abstract: A fuel injection system for a combustion engine having an injection valve with a fuel vaporizer into whose inlet orifice fuel can be injected from the injection valve and out of whose outlet orifice a fuel stream is discharged, and having an air supply system that supplies air to the fuel vaporizer for mixing with the fuel stream. To improve the fuel delivery from the fuel vaporizer, the air supply system has an air blow-out device mounted in the area of the outlet orifice of the fuel vaporizer through which the air to be added to the fuel stream is supplied to the fuel stream discharged from the fuel vaporizer.

Abstract: A fuel atomization device 10 is provided for an internal combustion engine having a fuel injection system with fuel injectors 15. The fuel atomization device is sealingly secured on a nozzle lip of the fuel injector nozzle. The device includes a base 1 in which a plurality of heating elements and profiled vaporizer contact baffles 3 are arranged in a sandwich-like manner. Vaporizer chambers 8 are formed between the heating elements 2 and the vaporizer contact baffles 3 for providing a passage for the fuel through the base 1. The fuel undergoes a rise in temperature and pressure while in the device; and as it exits the device at fuel outlet 6, it is atomized fuel at a lower pressure.
