Fuel storage and delivey apparatus of a multi-fuel engine and process

A fuel storage and delivery apparatus for providing one or more non-miscible fuels to a multi-fuel engine, comprising:

• a fuel reservoir adapted for storing first and second non-miscible fuels in communication with each other, said first and second fuels respectively defining a phase interface therebetween, said fuel reservoir having a bottom surface and a first outlet adapted to receive said first fuel and a second outlet adapted to receive said second fuel, said first and second outlets being respectively positioned adjacent said bottom surface and said phase interface;
• and
• a mixing chamber connectable in fluid communication with said first and second outlets, and to said engine, said mixing chamber being adapted to receive said first and second fuels and supplying a mixture of said fuels in a predetermined ratios, to said engine;
• means for respectively maintaining said first and second outlets adjacent said bottom surface and said phase interface;
• means for sensing the fluid levels of said first and second non-miscible fuels in said reservoir, and producing fluid level signals in response to the sensed fluid levels;
• flow rate sensing means for measuring fluid flow rate of said first and second non-miscible fuels passing through said fuel delivery apparatus, and producing a flow rate signal representative of the sensed fluid flow rate;
• a flow controller electrically connected to said level sensing means and said flow rate sensing means, said flow controller being adapted to receive said fluid level signals and said flow rate signals and maintain the flow rates of said first and second fuels passing through conduits at predetermined values, the values being a function of the fluid level signals and the flow rate signals.
