Water powered engine

Abstract

An engine which is fuelled solely by super heater water/steam in which the super heated water/steam is used to create power via thermal expansion. The water/steam is then condensed and then recirculated in a closed circuit arrangement so as to arrive at zero consumption and zero emissions.

1 : An internal expansion engine fueled solely by water a small quantity of which is superheated, at the moment of demand, the internal expansion engine comprising an electric heating element positioned immediately prior to an injector of an expansion chamber, the superheated water being used to create power via thermal expansion in the engine, the superheated water after use is condensed and recirculated in a closed circuit to arrive at zero consumption of water.  
   
   
       2 : An engine as claimed in  claim 1  wherein the water is super heated, at the moment of demand, in small enough quantities to satisfy an engine's immediate demand and is not supplied via a reservoir of steam.  
   
   
       3 : An engine as claimed in  claim 2  which employs electro-mechanically induced thermal expansion to create an environment where small quantities of water are conditioned by heat and pressure to the extent that minimal heat energy is needed to be expended to complete the expansion process.  
   
   
       4 : An engine as claimed in  claim 3  wherein the residue of the expansion process is condensed, post the expansion phase, and cooled just enough to return it to a liquid state.  
   
   
       5 : An engine as claimed in  claim 1  wherein the engine is an internal combustion engine in which water/steam is the sole means of creating power.  
   
   
       6 : An engine as claimed in  claim 1  wherein the water is time pulsed, metered and delivered at very high pressure and pre-heated beyond normal vaporisation temperatures.  
   
   
       7 : An engine as claimed in  claim 6  wherein the residual pressure of the water/steam is controlled so that latency, vaporisation does not occur within the delivery system.  
   
   
       8 . An engine as claimed in  claim 6  wherein the delivery system metering device when active, forces the water into the engine cylinders via injectors preset to open when a metering pump creates a pressure rise above closing pressure.  
   
   
       9 : An engine as claimed in  claim 8  wherein the pressure in the engine cylinders is much less than that in the delivery system so that the preconditioned water rapidly expands to create work in the cylinders.  
   
   
       10 : An engine as claimed in  claim 9  in which in each engine cylinder a further heating process takes place, via a heating element, to ensure completion of the expansion process.  
   
   
       11 : An engine as claimed in  claim 9  wherein the metering is controlled via a piston pump metering system or constant pressure electromechanical gating mechanism.
