ABSTRACT:
The injection device has a nozzle body with a needle valve controlled by id. At the front end of the nozzle body there are, in the case of a single hole nozzle, one injection channel and in the case of a multi-hole nozzle, several injection channels which may be at any angle to each other. In the narrowest cross section of the injection channel suction slots lead into the combustion chamber. Air is drawn in from the combustion chamber by the jet of fuel leaving the injection channel. This air mixes with the fuel in the narrowest cross section of the injection channel so that, at the base of the injection jet, there is a two-phase flow having particularly favorable properties for the subsequent mixture formation.
