Rakh cycle engine

Abstract

A new thermodynamic cycle engine consisting of six events repeated continuously. Event 1 is adiabatic compression of a carrier gas to raise its temperature. Event 2 is liquid Injection into the hot carrier gas near the end of event 1. Event 3 is temperature equalization between the carrier gas and injected liquid with the liquid's full or partial vaporization. Event 4 is adiabatic expansion of the mixture. Event 5 exhausts the mixture. Exhaust should be captured to save and separate the mixture into its components to increase efficiency. Event 6 is the induction of a new charge of carrier gas, bringing the cycle back to initial conditions of event one. This cyclical sequence of six events numbered from any starting point in an engine will be referred to as the RAKH CYCLE Engine. Devices reversing this cycle using compression to concentrate heat, and injecting water to cool the carrier gas are RAKH CYCLE Refrigerators.

1 . A thermodynamic engine using a heated carrier gas, compressed adiabatically to further increase temperature and induce rapid heat transfer into a nearly boiling liquid injected into the lower pressure, hot carrier gas, forcing vaporization due to a combination of the heat received from the high temperature carrier gas and its own excess enthalpy over its saturation enthalpy after injection into the lower than saturation pressure environment of the compressed carrier gas, yielding an overall pressure increase from the combined partial pressures at the point of maximum compression, which will then generate an excess of mechanical work via expansion over the work expended to compress the gas.  
   
   
       2 . An engine using a gas or combination of gasses, unburned, and compressed adiabatically to increase temperature for the purpose of accelerating transfer of additional heat to a previously heated injected liquid, or other substance above its critical temperature and pressure, which when injected to form a mixture, thereby produces a sum of partial pressures, without combustion after the induction of the carrier gas, greater than the carrier gas pressure at its most compressed volume, which produces a net work output.  
   
   
       3 . A thermodynamic refrigeration cycle, which uses any said real carrier gas in an adiabatic compression to concentrate thermal energy during the compression event to increase the temperature of the carrier gas and achieves rapid cooling upon injection of a liquid substance that takes up part of the heat of the carrier gas.  
   
   
       4 . An engine having any arbitrary selection of a first cycle event selected from the present RAKH Cycle with the remaining events in the same relative cyclical sequence described in the present invention, where the essence the cycle relies on a transfer of concentrated thermal energy in the form of increased temperature due to compression of a carrier gas and subsequent transfer of a portion of that thermal energy to an injected substance without resort to internal combustion, which increases overall mixture pressure after equalization of their temperatures to produce a net positive work output.  
   
   
       5 . An engine, independent of the number of strokes required to implement the thermodynamic cycle, not excluding a turbine or any other mechanical compression type engine, which implements the said thermodynamic cycle in the sequence specified or continuously at various locations in the engine simultaneously, as in a turbine.
