ABSTRACT:
A supplemental fuel supply system for use in an internal combustion engine having a fuel supply and using an on-demand supplemental oxygen supply includes a fuel pump and a supplemental oxygen supply regulator. The pump has a fuel supply and a fuel discharge. The pump includes an inlet for feed from the supplemental oxygen supply. The pump is driven by a portion of the supplemental oxygen supply such that when a demand is made on the on-demand supplemental oxygen supply to supplement oxygen to the internal combustion engine, a portion of the supplemental oxygen is introduced into the fuel pump to drive the fuel pump to discharge fuel therefrom to the internal combustion engine. The discharge from the supplemental oxygen supply regulator supplies both the fuel pump and the internal combustion engine.
