Abstract

A fuel vaporization system applicable for use on internal combustion engines. The fuel is supplied from a normal fuel supply (7) through a conduit (11) connected to the input of a tripartite valve (3) and from there directly to the main carburetor (1) or to the vaporizer (3) where the fuel is passed through a coil of tubing (4) heated by electronic resistor (5) and heated to the point of vaporization and then passed out of the vaporizer to the main carburetor (1).

Description

FUEL-VAPORIZING SYSTEM OF CARBURETION

The present patent refers to an apparatus whose purpose is to reduce the consumption of any type of fuel (gasoline, alcohol, kerosene, diesel oil, etc.) without affecting the power output.

The device can be installed in any type of vehicle propelled by a combustion engine (OTTO or DIESEL cycle), increasing the distance covered per liter of fuel.

On the drawings which are part of this report, or more precisely in figures 1, 2 and 3, we can see that there is no need to remove any part from the engine in the vehicle; that is, the engine may utilize its own system of carburetion and/or the system proposed in this descriptive report, with the simple disconnection of the tripartite valve (item 05 in figure 03).

Because of its extreme simplicity, the apparatus herein described practically does not require any type of maintenance; that is, in case of malfunctioning, as mentioned above, it will be enough to remove the unit installed in the vehicle.

Another important point to be emphasized (besides the financial gains for individuals, private companies and governments) is the benefit from its use (especially in great cities) in terms of public health since it will provide a reduction in pollution of approximately 75% in the levels of ambient pollution. The drawings that are an integral part of this report are the following:

Figs. 08, 09 and 10: Triple Electric Valve - views

Fig. 12: Metal housing for mounting the equipment - views The apparatus that was manufactured for testswas subsequently installed in a vehicle that has the most complicated gasoline engine in the world, besides being a vehicle with the highest fuel consumption; we refer to the 1983 CADILLAC LIMOUSINE, engine type 4-6-8, with complete fuel injection system.

The results obtained were excellent, a guarantee of a still better performance when used in any other types of vehicles.

By observing the illustrations and drawings hereto attached (especially fig. 02, Interior Section of the Vaporizer, and 03, Flow Diagram), it can be seen that the device is installed with only three (3) connections; two (2) of which provide for the entry and exit of the fuel (items 01 and 02 in fig. 02 and items 13 and 14 in figure 03) while the third is for the electric connection of the tripartite valve (triple electric valve) and the thermostat (item 03 in fig. 02 and item 15 in fig. 03).

When the tripartite electric valve is turned on (item 05 in fig. 03), the normal supply of fuel (item 11 in fig. 03) is cut off from the carburetor (item 01 in fig. 03) and the flow is redirected (item 12 in fig. 03).

As the flow goes through 15,240 mm of tubing (item 04 in fig. 02), the fuel is heated by the energy provided by the electronic resistors (fig. 11 and item 05 in fig. 02) to the "point of vaporization." The fuel vapor passes through the high-pressure tubing (item 09 in fig. 03), proceeds through connection "T" (item 02 in fig. 03), and from there it enters the carburetor (item 01 in fig. 03); in this manner, the vapor is partially condensed, bringing with it a bit of liquid in the shape of humidity droplets which are necessary for the operation of the electronic system of fuel injection (in the case of vehicles equipped with this type of system).

For all other types of vehicles, the distance from the vaporizer to carburetors "non electronic" acceptance the pure vapor with the mixture of air within the carburetor, for normal functioning of the engine.

The function of the thermostat (item 04 in fig. 03) is to regulate and maintain automatically the best operating temperature for each type of engine.

Besides that, on the intake side (item 01 in fig. 02) of the vaporizer there is a controller (item 16 in fig. 03 and fig. 04, 05, 06 and 07) of the jet of flow for the liquid fuel, which is adjustable for vehicles with engines of 4, 6, or 8 cylinders.

This controller of jet of flow is necessary because the amount of fuel required for the vaporization system is much smaller than that demanded by vehicle manufacturers for normal functioning of their engines. An exploded view of the jet controller appears in fig. 06.

The entire excess of fuel supplied by the fuel pump (item 06 in fig. 03) in the vehicle is conveyed to the line of flooding or excess flow (item 08 in fig. 03) and returns to the vehicle fuel tank to be reused (not heated).

Should there be any problem of operation with the apparatus, it would be enough to turn off the tripartite valve; in which case the engine will function normally under its original manufactured conditions, that is, through the main line (item 10 in fig. 03). The vaporizer protection (fig. 01) is simply a prototype for tests; the part, to be produced in series, will have the final shape of a box measuring approximately 177.8 x 152.4 x 101.6 mm (7" x 6" x 4"). All the connections, valves, joints and reducers are now in normal production and for sale in the market. There will be three (3) versions of the device, all with the same efficiency. Two such versions will be applicable to all types of engines operating with gasoline, alcohol, etc (OTTO cycle); the third version will be meant for stationary engines or DIESEL cycle engines.
