A dual-substance nozzle (3) for injecting fuel and supplementary fluid into a combustion chamber of an internal combustion engine, having a nozzle body (3.0) with at least one inlet bore (3.2) for delivery of fuel at high pressure into the dual-substance nozzle (3), and nozzle bores (3.8) for injecting fuel from the dual-substance nozzle into the combustion chamber. A jacket (7), preferably metal, is disposed around the nozzle body (3.0) enclosing at least one hollow chamber (8), adjoining the outside of the nozzle body (3.0) and extending around the nozzle body (3.0) for receiving supplementary fluid. A feed line (5) for delivering supplementary fluid at high pressure into the hollow chamber and one or more injection nozzles for injecting supplementary fluid from the hollow chamber into the combustion chamber are provided. The injection of fuel and supplementary fluid are separate, insuring no mixing thereof upstream of the combustion chamber.
