Novel Fuel Sensor - Innovation for Cold Start Improvement and for the Prevention of Misfuelling

The fuel sensor determines quickly and reproducibly the evaporation characteristics of the fuels based on the heat flow of a heating element. Thus the micro sensor can classify the cold start characteristics of the different Gasoline fuels and can distinguish different diesel derivatives. For diesel vehicles, an electronic false refueling protection was realized based on a sensor installation into the fuel receptacle. It combines the advantages of an analysis of the diesel derivatives with that of a fast warning in the case of misfuelling.
