Abstract: What is proposed is an emulsifying system for an internal combustion engine, wherein the emulsifying system comprises an emulsifying device for producing a water-fuel emulsion and an injector for injecting the water-fuel emulsion in a combustion chamber, the emulsifying device being arranged within the injector. Also proposed is an emulsifying method for preparing a water-fuel emulsion for an internal combustion engine, wherein fuel is pressurized in a fuel pressure accumulator and water is pressurized in a water pressure accumulator and fed separately to an injector for injecting the fuel and water into an associated combustion chamber, and/or fuel and water are emulsified by means of an emulsifying device that is integrated into an injector.

Abstract: What is proposed is an emulsifying system with an emulsifying device and an injection nozzle as well as an emulsifying device for producing a water-fuel emulsion for an internal combustion engine, wherein the emulsifying device is embodied as a rotor-stator emulsifying device and/or fluid flow machine and/or is connected or connectable directly to an injection nozzle. The emulsifying device has a housing and a shaft, the shaft being drivable in a contactless manner, the housing having a guide apparatus having a plurality of guide channels for guiding the flow, and/or the housing being made at least partially from fiber composite material.

Abstract: The invention proposes a method and an emulsifying apparatus for the operation of a diesel engine with a water-diesel fuel emulsion, wherein the water fraction is varied as a function of the engine operating point and/or the emulsifying apparatus and/or parts of the injection line are flushed with pure diesel fuel upon a shutdown of the engine.
