Claim Text:
1. An injection device for an internal combustion engine, comprising: a first injection system for injecting a fuel having a first fuel composition; and a second injection system for injecting a fuel having a second fuel composition with a lower ethanol component than the first fuel composition, the first injection system having at least one first fuel injector for injecting the 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 the fuel having the second fuel composition essentially only in the direction of the first intake orifice, and a separate third fuel injector for injecting the fuel having the second fuel composition essentially only in the direction of the second intake orifice, wherein the distance between the second fuel injector and the first intake orifice, and the distance between the third fuel injector and the second intake orifice is smaller in each case than the distance between the at least one first fuel injector and the first or second intake orifice, and wherein at least one of the second fuel injector and third fuel injector are configured to inject the fuel having the second fuel composition into the combustion chamber such that the fuel having the second fuel composition evaporates in the combustion chamber and the combustion chamber is cooled.
