Abstract
A fuel injection method and system for a Diesel engine, with an injection nozzle (1) supplied with a first fuel through a high-pressure pump (3) through a reservoir (2), wherein the engine can operate--rather than with the first fuel--with the second fuel in the form of pure fuel or of an emulsion of fuel and another substance that is insoluble in the fuel. Means are provided by which the second fuel is guided in a circuit through injection nozzle (1) and the second fuel, when the injection nozzle is actuated, is injected into the engine through the first fuel, which is under high pressure, from reservoir (2) to injection nozzle (1), with the mixture ratio of the fuel and additional substance in the second fuel being adjusted in the circuit.
