Abstract
Abstract The fuel consumption of an internal combustion engine is decreased by the sue of steam, wherein the steam is produced by maintaining a constant flow of water past the internal combustion engine which acts as the boiler, without the need for any external source of heat. The steam that is produced is injected in a timed, pulsed manner into the engine at such a time as to allow the expansion of the steam in the chamber to supplement the expansion of the gases caused by the explosion of the fuel consumed.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
170 words
A device to supplement the power produced by burning fuel in an internal combustion engine with steam, said device comprising: a means for producing a constant flow of water past a boiler means; a means for allowing the said water to flow in the direction of the said boiler; a boiler means external to the said internal combustion engine to convert the said water into superheated steam; a means for controlling the pressure of the said water such that the said water pressure is greater than the pressure of the said steam produced by the said boiler; and a means for injection of the said superheated steam directly into a cylinder of the said internal combustion engine, a means for producing a constant flow of water at a pressure greater than the pressure of said superheated steam, wherein said constant flow means at greater pressure comprises a chamber with a gaseous component, with said gaseous component being of constant volume and exerting constant pressure upon water within the said chamber.
Claim 2
Independent Claim
170 words
A device to supplement the power produced by burning fuel in an internal combustion engine with steam, said device comprising: a means for producing a constant flow of water past a boiler means; a means for allowing the said water to flow in the direction of the said boiler; a boiler means external to the said internal combustion engine to convert the said water into superheated steam; a means for controlling the pressure of the said water such that the said water pressure is greater than the pressure of the said steam produced by the said boiler; and a means for injection of the said superheated steam directly into a cylinder of the said internal combustion engine, a means for producing a constant flow of water at a pressure greater than the pressure of said superheated steam, wherein said constant flow means at greater pressure comprises a chamber with a gaseous component, with said gaseous component being of constant volume and exerting constant pressure upon water within the said chamber.
Claim 3
Dependent Claim
25 words
The boiler means described in claim 1 wherein the said boiler means is the heat radiating from the exhaust system of the said internal combustion.
Claim 4
Dependent Claim
23 words
The injection means described in claim 1, wherein the said injection means is a timed, pulsed injection control by an external timing device.
Claim 5
Dependent Claim
33 words
The device in claim 3, wherein the said timed, pulsed injection of steam is maintained at a pressure wherein the said timed, pulsed injection of steam is less than the said water pressure.
Claim 6
Dependent Claim
28 words
The device in claim 1, wherein the said means for allowing the said water to flow in the direction of the said boiler comprises a uni-directional valve means.
