Fuel blending system, method and apparatus

摘要

The system includes an adjustable blending valve with two entry ports and one exit port. Each entry port is connected to the discharge line of the respective fuel pumps. A blending valve includes a spool device which as it moves, increases the portion of one reference fuel as it decreases the portion of the other fuel to vary the octane rating of the blended-flow from the exit port. A float controlled needle valve is positioned in the mixed fuel flow path which limits the mixed fuel flow to that which the engine is burning. An integral processing device which senses a flow from included flow meters to compute a percent of each test fuel A and B in the blend and the octane rating of the blended stream.
