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.
