METHOD AND SYSTEM FOR PREVENTING VEHICLE MISFUELLING

摘要

A method and system for preventing vehicle misfueling by utilizing an apparatus (300) that receives a fuel nozzle into the filler neck (302), and activates a vacuum on the nozzle inserted therein. Using the pump~s internal shut-off mechanism, this prevents the fuel pump from dispensing fuel until t he sensing unit (310) within the apparatus (300) is able to identify the fuel proposed to be added to the tank. If the fuel is deemed acceptable, the vacu um is released, and the fuel is permitted to enter into the desired fuel tank.< /SDOAB>
