A system for blending low and high octane gasoline includes independent flow paths for each fuel between a supply source and a composite blend manifold and nozzle assembly, with the rate of flow of fuel in each flow path being under individual closed loop control, under an algorithm for comparing the ratio of the actual accumulated volumes of the low octane to the high octane fuel, relative to a statistically determined ratio of the ideal volume of said low to high octane fuel for the total actual accumulated volume of the sum of the volumes of the fuels at a given time, for providing a perfect blend relative to a preselected blend ratio.

A system for blending low and high octane gasoline, comprising: nozzle means for dispensing the blended gasoline, said nozzle means including blend manifold means having a first port for receiving low octane gasoline, a second port for receiving high octane gasoline, and a mixing chamber for blending received high and low octane gasoline together just prior to dispensing; a first flow path for delivery of said low octane gasoline from a source thereof to said first port; a second flow path, wholly independent of and isolated from said first flow path, for delivery of said high gasoline fuel from a source thereof to said second port; first flow control means responsive to a first control signal for controlling the rate of flow of gasoline in said first flow path; second flow control means responsive to a second control signal for controlling the rate of flow of gasoline in said second flow path; blend selection means for producing a blend set point signal indicative of a desired blend ratio of said low and high octane gasoline; and processor means responsive to the flow of said low and high octane gasolines for producing, after a predetermined initial volume of gasoline has been dispensed, said first and second control signals at any given time as a function of a comparision of the ratio of the actual accumulated volume of said low octane gasoline to said high octane gasoline, relative to a statistically determined ratio of the ideal volume of said low octane gasoline to said high octane gasoline for the total actual accumulated volume of the sum of the low and high octane gasoline at a given time, said processor means including means responsive to said blend set point signal for producing an idealized ratio equivalent to at a given time what the accumulated volumes of said low and high octane gasolines must be for providing said selected blend.
