Blending fuel wherein two fuels are passed through a single meter and through a sensor signalling the octane level of the mixture

摘要

The fuel dispensing apparatus consists of: first and second fuel sources 100, 200 of different octane levels; a blending system (typically with blend selectors 353) including respective flow control valves 306, 308 to control the first and second fuel flow rates; first and second octane level sensors 102, 202 to sense respective octane levels; site controller 400 for receiving octane signals and controlling blending by determining if a predetermined blend can be created based on the measured octane levels and to permit fuel dispensing only if such a blend can be achieved; and a fuel dispenser nozzle 10.
