Abstract
An internal combustion engine, in a motor vehicle, has a fuel filter system in a fuel line leading to the internal combustion engine. The operation of this motor vehicle exclusively with fuel of filtered quality is ensured. To this end, a valve is provided inside the fuel line preventing the internal combustion engine from being started when the fuel is unfiltered.
