ABSTRACT:
A system for modifying and utilizing hydrocarbon fuels in the operation of internal combustion engines wherein increased fuel efficiency and reduction in amount of polluting products of combustion produced are realized. Hydrocarbon fuels normally entirely consumed in the operation of internal combustion engines are modified by separating lighter, highly volatile fractions of a paraffinic and ultrafast burning nature from the fuels and utilizing substantially only the lighter fractions for fueling the internal combustion engine, with the heavier fractions being stored separately from the original hydrocarbon fuel source. The lighter fractions permit operating the engine with a lean fuel mixture having a higher than stoichiometric air-to-fuel ratio, thereby better accommodating the characteristic intermittent fuel demand of the operator, reducing the production of undesirable nitrogen oxides, permitting the engine to operate at reduced operating temperatures and prolonging the useful life of engine components.
