Abstract: A diesel engine fuel system of the type which includes a fuel heater upstream of a filter in the fuel feed line from the tank to the engine injector and wherein a diverter line is connected at one end in the engine-to-tank return line and at its other end to the feed line downstream of the filter. A valve controls flow in the diverter line and is adapted to permit flow therein while substantially stopping return flow to the tank only when the heater is operating. The result is a dramatic improvement in heater efficacy.

Abstract: A carburettor or other combustible mixture generator 1 has a mixture chamber 3 surrounded by a tubular wall 2 which has an inner skin 9 and an outer skin 10 with an annular heating chamber 11 between them. Heating fluid such as exhaust gas or heated engine cooling water flows through the chamber 11 from an inlet 12 to an outlet 13 and so heats the inner skin 9. A fuel metering device 6, 7 directs the fuel on to the surface of the heated skin 9 and thus causes the fuel to be evaporated within the mixing chamber 3 upstream of a throttle 4. This greatly improves the uniformity of the mixture and the uniformity of its distribution through an inlet downstream of the throttle 4.

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.
