Abstract
In a method for operating an internal combustion engine of a motor vehicle, in particular, pressurized fuel is conveyed to a fuel accumulator. The fuel is injected into a combustion chamber via a fuel injector. Coking of the fuel injector is determined. A first fuel-pressure increase is implemented when the coking exceeds a threshold value.
