    Abstract: A combination internal combustion and steam engine includes a cylinder having a piston mounted for reciprocation therein with an internal combustion chamber and a steam chamber in the cylinder adjacent the piston and at least one steam exhaust port positioned to communicate with the steam chamber through the wall of the cylinder for exhausting steam at a location in the cylinder wall adjacent to an engine cylinder cap surface that is heated externally to assist in reducing chilling or condensation of steam entering the steam chamber from a boiler fired by waste combustion heat. The invention also permits steam admitted from a steam chest jacketing the cylinder cap to be exhausted from the engine when the steam chamber is in an expanded state whereupon residual steam is then recompressed prior to admitting the next charge of steam with the stream in the steam chamber being heated directly by the combustion chamber as well as by heat from the steam chest. An I.C. exhaust powered heater is a part of an I.C. exhaust manifold which functions as an afterburner with supplemental air injection for promoting combustion of unburned exhaust constituents to superheat steam that is piped through it to the steam chest. The invention provides valves for balancing steam engine displacement with boiler output and for cylinder compounding with a boiler, heat exchange and control arrangement for efficiently recovering waste heat.

    Abstract: A pre-heater arrangement in a heat regenerative engine for pre-heating water in its delivery path from a condenser sump to a combustion chamber. The engine includes a steam generator, including the combustion chamber, for producing pressurized steam. The engine further includes at least one piston and cylinder arrangement for receiving the pressurized steam in order to drive the piston within the cylinder, and a condenser for condensing steam to liquid. A conduit formed of a heat transferring material provides the delivery path from the condenser sump to the combustion chamber. The pre-heater arrangement includes at least one exhaust port associated with the cylinder for releasing steam from within the cylinder after driving the piston, and a tubular coil connected to the steam delivery conduit and wound about the cylinder, adjacent to the exhaust port, for transferring heat from the exhausted steam to the water traveling through the coil, thereby heating the water on its delivery path to the steam generator. In giving up heat to the pre-heater coil, the exhausted steam begins the process of cooling on its path from the cylinder exhaust port to the condenser where the steam is condensed to a liquid and returned to the sump.

    Abstract: In a heat regenerative engine that uses water as both the working fluid and the lubricant, water is pumped through a single line of a coil that wraps around a cylinder exhaust port, causing the water to be preheated by steam exhausted from the cylinder. The preheated water is then directed through multiple branch lines in a steam generator to produce high pressure super heated steam. A splitter valve at the juncture of the single line and multiple branch lines equalizes the flow among the multiple branch lines. A “Y” junction within the splitter valve minimizes turbulence as the flow of water and steam is directed into the multiple branch lines. Flow control restrictors in the splitter valve allow unimpeded flow of fluid and steam towards the steam generator through each of the branch lines, while allowing any incremental over-pressure in any one branch line to “bleed” back to a branch line(s) bearing a lesser amount of pressure, thereby equalizing flow through the multiple branch lines.

    Abstract: A stem engine has a fluid container, a heating device and a cooling device. The fluid container has an outer pipe having an upper closed end, and an inner pipe provided in the outer pipe and having a fluid inlet port through which the inside of the inner pipe is operatively communicated with the outside of the inner pipe. The inner pipe has a pressure control device at its lower end, and a fluid injection port at its upper end for injecting the working fluid in the inner pipe into a space defined between the inner pipe and the outer pipe, when the pressure in the inner pipe is increased. The working fluid injected into the space between the inner and outer pipes is heated and vaporized by the heating device, so that volumetric expansion of the working fluid takes place to increase fluid pressure in the fluid container. The vaporized steam is then cooled and liquidized by the cooling device and thereby the volumetric contraction takes place, so that the fluid pressure is decreased. By repeating the above volumetric expansion and contraction of the working fluid, the pressure change is given to the working fluid in the fluid container.

    Abstract: In a steam motor with a piston engine, the piston engine is included in a closed steam circuit. This steam circuit includes a steam generator, a steam injector for injecting steam into the piston engine, a condenser for condensing the steam emerging from the piston engine to condensed water, and a water feeding pump for feeding the condensed water to the steam generator. The steam generator is heated by hot combustion gas from a combustion unit. The combustion unit burns fuel. The fuel is mixed with fresh air supplied by an air feeding device through a fresh air passage. The fresh air passage usually contains a first heat exchanger for pre-heating the fresh air by heat from the expanded steam emerging from the piston engine, and a second heat exchanger for pre-heating the fresh air by heat from hot waste gas emerging from the steam generator. In order to provide a particularly compact steam motor without adversely affecting the efficiency, a rotary piston engine is used as piston engine.

    Abstract: A vapor powered electro-mechanical generator comprises a cylinder, which is sealed at both ends in which two pistons slidingly move in opposite directions simultaneously. A tube on which the pistons also slide lies at the center of the longitudinal axis of the cylinder. The tube transfers vapor from the inlet to the pressurized side of the pistons to actuate pistons, while one or more exhaust valves are simultaneously opened on the opposite end of the piston stroke allowing the expanded vapor to flow to a condensing system. The pistons consist of magnets at their peripheral circumference. As the vapor expands, the pistons magnets move through coils of conductive wire producing electric current. Further, repulsion magnets repel corresponding piston magnets to provide a cushioned rebound effect while conserving momentum of the generator.

    Abstract: A hybrid heat engine system includes a chamber housing including an inlet and an outlet. A piston is disposed in an interior volume of the chamber housing. The hybrid heat engine system further includes a valve configured to provide a first fluid in a heated state from a heat source to the interior volume via the inlet. The first fluid in the heated state is to push against a first side of the piston to cause a second side of the piston to push a working fluid out of the interior volume and through a turbine to generate energy.
