Claim:
1. A method for operating an internal combustion engine comprising at least one fuel injection valve for introducing fuel into a combustion chamber of the internal combustion engine, the method comprising: supplying the valve with a specific current intensity using pulse width modulation in order to set a specific throughflow cross section of a fuel flow connection into the combustion chamber, setting the specific current intensity to be equal to a first current intensity during a normal operating mode of the internal combustion engine and setting the specific current intensity to be equal to a second current intensity during a clearing operating mode, wherein the second specific current intensity is higher than the first specific current intensity, and the specific throughflow cross section is set at a maximum during the clearing operating mode, and the specific throughflow cross section is set to less than the maximum during the normal operating mode.
