Abstract

Abstract of the Disclosure The invention comprises a chamber to be mounted between a carburetor and an intake manifold of an internal combustion engine so as to provide increased gasoline mileage and reduced exhaust pollutants.

Description

6~457 This invention relates to the field of efficiency of, and pollution abatement in, internal combustion engines.
Many modifications have been made to internal combustion engines to increase their efficiency and decrease their fuel consumption. At the same time, advances have been made in controlling the various gaseous pollutants emitted from internal combustion engines. Known devices for achieving these ends are often complexJ difficult to service, and expensive. The present invention is surprisingly simple and can be fitted onto existing engines to yield greater engine efficiency and, at the same time, to reduce the amount of gaseous pollutants emitted. The production of carbon monoxide is especially ~ -reduced.
Although the theory of why the device according to the invention operates is unknown, the results of the use of the device are significant.
~; The invention is a chamber adapted to be mounted between a carburetor :, :
, and an intake manifold in an internal combustion engine wherein the chamber has .
~.; a first opening on a first face of the chamber, the dimensions of the first ^~i . : .~ ~ opening adapted to conform the dimensions of the outlet port on the carburetor, , a second opening on a second face which is opposite and parallel with the first face, the second opening being aligned with the first opening, the dimensions of the second opening adapted to conform with the dimensions of the inlet port of the intake manifold, connecting means proximal the first and second openings whereby the chamber is capable of being connected between the car-buretor and the intake manifold, and the ratio of the volume of the passage , in the chamber between the first opening and the second opening to the total ~; .
` internal volume of the device is in the range of 1:6 to 1:10.
Since the device in use is mounted between the intake manifold of the engine and the carburetor, the path length of the airluel mix is ; i. ;~
increased and may result in more thorough vaporization of the fuel.

An embodiment of the invention will be hereinafter described with reference to the accompanying drawings, in which:

Figure 1 is a schematic drawing of the device as installed 6etween 3 an intake manifold and a carburetor, and Figure 2 is an isometric drawing of the device, ,., ~ -1-1~ 57 Figure 1 shows schematically the atomizer device 6 mounted between the base portion 2 of a carburetor 1 and the intake manifold 8 with suitable gaskets 7 therebetween. The upper surface 11 and the lower surface 12 of the atomizer 6 are parallel with each other. The device may be of any shape, for example round or rectangular and it may also be indented so as to fit around - part of the carburetor or engine. Holes 15 in the upper surface 11 are in ~- alignment with similar holes in the lower surface and are adapted to receive bolt studs 4. Connection is by means of nuts 3. The bolt studs are the same as normally provided on an engine except that they are somewhat longer so that they may accommodate the thickness of the atomizer. Support sleeves 9 extend in sealing manner between the upper and lower surfaces. These sleeves 9 are coaxial with and slightly larger than the holes 15 which receive the bolt studs 4.
The drawings show a bore 5, with a plug 10 therein (Figure 2).
Plug 10 can be removed, and an electrical heater element inserted to provide heat and thus assist in starting the engine on cold days. The electric heater could be placed in a trough containing fuel and thereby aid starting of the engine on cold days. In addition, the bores can be used to vacuum test the air tight mass of the joints in the chamber.
Opening 13 is centrally located in the upper surface 11 of the device 6. Similarly and in alignment therewith is opening 14 in the lower .
surface 12 of the atomizer. The size and shape of opening 13 is the same as the size and shape of the opening in the exit of the carburetor. In the same way, the size and shape of the opening 14 in the lower surface 12 is the same as the size and shape of the opening of the intake port of the intake manifold.
Since normally the opening in carburetor exit matches the opening in the intake manifoldl all these openings are of the same size and shape.
The inside depth of the device 6 is approximately one inch. Also the ratio of the volume between the openings 13, 14 and the internal volume of the device is in the range 1:6 to 1:10 but preferably is 1:8. Since the J
size of the opening for the carburetor is matched for the engine capacity, the size of the device will also be matched to the capacity of the engine.

~(~63457 This device facilitates an improved air/fuel mixture entering the intake manifold of an internal combustion engine. The spray of fuel mixture combines with the flow of air in the carburetor and enters the chamber, the internal space of which is below normal atmospheric pressure. Turbulence results in this chamber and because of the turbulence and par~ial vacuum, improved vapourization results. As a result of the improved vapourization and mixing there is a reduction in fuel consumption, improved engine efficiency and reduced gaseous pollu~ant emitted.
