Abstract

An injection device for an internal combustion engine having a first injection system for injecting fuel having a first fuel composition, and a second injection system for the injection of fuel having a second fuel composition that has a lower ethanol component than the first fuel composition, the first injection system having at least one first fuel injector for injecting fuel having the first fuel composition both in the direction of a first intake orifice of a combustion chamber of the internal combustion engine, and in the direction of a second intake orifice of the combustion chamber, wherein the second injection system has a second fuel injector for injecting fuel having the second fuel composition essentially only in the direction of the first intake orifice, and a separate third fuel injector for injecting fuel having the second fuel composition essentially only in the direction of the second intake orifice.
