ABSTRACT:
A fuel storage and delivery apparatus for providing one or more non-miscible fuels to a multi-fuel engine has a fuel reservoir adapted for storing first and second non-miscible fuels in communication with each other. The first and second fuels define a phase interface therebetween. The fuel reservoir has a bottom, and first and second outlets adapted to respectfully receive first and second fuels. The first and second outlets are positioned adjacent the bottom and the phase interface. The fuel delivery apparatus has means for respectfully maintaining the first and second outlets adjacent the bottom and the phase interface. The fuel delivery apparatus also has means for sensing the fluid levels of the first and second non-miscible fuels in the reservoir, and producing fluid level signals in response to the sensed fluid levels. The fuel delivery apparatus further has flow rate sensing means for measuring fluid flow rate of the first and second non-miscible fuels passing through conduits and producing a flow rate signal representative of the sensed fluid flow rate. The fuel delivery apparatus still further has a flow controller electrically connected to the level sensing means and the flow rate sensing means. The flow controller is adapted to receive the fluid level signal and the flow rate signal, and maintain the flow rate of the first and second fuels at predetermined values, the values being a function of the fluid level signal and the flow rate signal.
