Title:
METHOD AND STRUCTURE FOR PREVENTION OF INCORRECT FUELING OPERATIONS FOR DIESEL-POWERED VEHICLES
Document Type and Number:
WIPO Patent Application WO/2012/167062
Kind Code:
A4
Abstract:
A method and structure are described for preventing the accidental introduction of gasoline into the fuel system of a diesel-powered vehicle. In a first preferred embodiment, a gasoline fuel nozzle is configured with a magnet, such as magnetic strips, and the entrance to a fill tube of a diesel-powered is configured with a magnetic field sensor ring. When an incorrect fueling operation, such as the introduction of gasoline into the fuel tank of the diesel-powered vehicle, is attempted the sensor ring alerts the operator visually and/or audibly before fueling starts, thereby preventing incorrect fueling. In alternative embodiments, sensing of an attempted incorrect fueling operation may require only the sensor ring.
