[0003] Not ApplicableBACKGROUND OF INVENTION

[0004] Low grade fuels (low density, low heating value solid, liquid and gaseous substances) are not competitive with higher grade commercial fuels in small scale (e.g., less than 2000 kW) mobile and stationary power plants. This is mainly due to the lack of small scale, efficient, low cost steam prime movers that can economically convert low grade fuels into usable, industrial power.

[0005] The traditional reciprocating steam engine, in its various forms, has become economically and technologically obsolete due to the availability of refined, petroleum based fuels that were better utilized in more efficient heat engine cycles (Otto, Diesel and Brayton cycles) and the development of low cost electrical power delivered by the interconnecte...

Embodiment Construction

[0031]The present invention is described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. This invention may, however, may be embodied in many different forms and should not be construed as limited to the embodiments set for herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the scope of the invention to those skilled in the art. The current invention is a high speed, two-stroke engine that is counter flow, semi-uniflow, or uniflow and is comprised of at least one variable rotary valve mechanism. Working fluid, referred to herein, may be organic and / or inorganic fluid, naturally occurring and / or man-made. Working fluid may include: Chlorofluorocarbon (CFC) (e.g. R-11, R-12); Hydro-fluorocarbons (HFC) (e.g. R-134a, R-245fa); Hydro-chlorofluorocarbon (HCFC) (e.g. R-22, R-123); Hydrocarbons (HC) (e.g. Butane, methane, pentane, propane, et...
