Abstract:
1. A supplemental fuel injection system for internal combustion engines comprising: a supply of primary fuel; a device supplying said primary fuel to an internal combustion engine; an air compressor supplying air to said internal combustion engine; a pressure monitor in an air outlet side of said air compressor, said pressure monitor monitoring the pressure of air leaving said air compressor; a temperature sensor in an exhaust of said internal combustion engine, said temperature sensor measuring the temperature of said exhaust of said internal combustion engine; a device supplying supplemental fuel to said air prior to said air entering said internal combustion engine; and a control device controlling the device supplying supplemental fuel, said control device including a programmable microprocessor connected to said device supplying supplemental fuel to vary the amount of supplemental fuel on an as needed, customized and preprogrammed basis for said internal combustion engine; said device supplying said supplemental fuel to said air includes a heat exchanger, said heat exchanger having a first inlet supplying said supplemental fuel in liquid form to said heat exchanger, a first outlet removing said supplemental fuel in a gaseous form from said heat exchanger, a second inlet supplying said air to said heat exchanger and a second outlet removing said air from said heat exchanger at a temperature lower than the temperature of said air entering said heat exchanger, said air exiting from said heat exchanger entering said internal combustion engine.
