AR PUMP-ASSISTED HYDROGEN/OXYGEN gas from the electrolytic cell into the intake air. FUEL CELL FOR USE WITH INTERNAL While there is nothing in particular which is theoretically COMBUSTON ENGINE wrong with either of these approaches, we have found that in practice neither method works reliably or predictably. For example, the PCV vacuum-operated system seems to work

FIELD OF THE INVENTION reliably with some vehicles but not in others. This may be due to susceptibility to the ambient humidity or temperature,

This invention relates generally to internal combustion the condition of the PCV system, cleanliness of the PCV engines having an auxiliary electrolytic cell which produces valve itself, whether the PCV system has a vacuum leak or hydrogen and oxygen gas to enhance combustion efficiency. 10 a vacuum leak exists somewhere else, the general extent to which the engine is "in tune', and other factors which

BACKGROUND OF THE INVENTION contribute to the magnitude and quality of the vacuum force provided by the PCV system.

For quite some time now, there have been two major areas The performance of a compressed air delivery system is of concern with the millions of fossil fuel-driven internal 15 combustion engines in use in automobiles, heating systems, also unpredictable in practice, there being many potential power generators, and the like. A first problem is in the sources of difficulties with such systems. For example, pollution of the atmosphere caused by the noxious gases although the compressed air source typically available on an generated as by-products of combustion. A second problem eighteen wheel diesel truck is first fed through an air filter, is in the increasing shortage of the fossil fuels on which such 20 to ensure that oil is not mixed in with the compressed air, some oil contamination inevitably seems to occur regardless engines depend. A substantial amount of research has thus been done with the objective of increasing the efficiency of of how careful the operator is. Once oil is mixed in with the existing engines so as to use less fuel, as well as searching electrolytic process, it possibly combines with the hydrogen for alternative sources of energy. gas in some way to adversely affect the electrolytic process. In other

It has been known for many years that hydrogen has 25 may be difficult instances, the required Venturi may clog or rust, or numerous advantages over fossil fuels. For example, hydro to locate the required Venturi, air filter, and pressure regulator in a place which is not prone to damaging gen has a potential heat energy almost three times greater vibration. In a number of other instances, the air filter than any other fuel. In addition, hydrogen burns cleanly, producing only water as a combustion by product. Hydrogen air reachesclogged becomes with oil to such a degree that little or no the Venturi, thereby limiting the Venturi's ability can also be made from water by several processes, one of the 30 to transfer hydrogen and oxygen from the electrolytic cell to most convenient being simple electrolysis. the intake air.

However, the substitution of hydrogen for gasoline and other fossil fuels in engines presents practical problems SUMMARY OF THE INVENTION which have delayed commercial acceptance, probably for several reasons. Primary among these has probably been the 35 It is thus a general object of this invention to provide an fact that hydrogen stored in its pure form presents a high improved hydrogen supplementation system which over potential for explosion. comes the above-mentioned disadvantages of previously Therefore, a number of researchers have pursued the known systems.

Such cells typically use the lution and increases fuel efficiency, while at the same time electrical energy from a battery in a vehicle engine and/or being inexpensive, readily installed, reliable, and predict other nearby electrical source to provide hydrogen by the able, and which does not require modification of existing electrolysis of water. 45 emission control systems or the use of auxiliary compressed It has been found that when hydrogen from such a cell is air source.
