A heat engine system comprises a first heat exchanger, an expander, a second heat exchanger and a valve assembly. The first heat exchanger is in fluid communication with a heat source for heating a working fluid therein. The expander is downstream the first heat exchanger and is in fluid communication therewith for receiving the heat working fluid. The second heat exchanger is downstream the expander and in fluid communication therewith for cooling down the working fluid received therefrom. The valve assembly is in fluid communication with the second heat exchanger and the expander for providing for selectively injecting the expander with cooled working fluid from the second heat exchanger.

Heat engine system for power and heat production

Power systems, heat exchanger systems, electrical regeneration systems and air drag reduction systems for a wheeled vehicle are provided. The systems comprise a vehicle that includes a compressed air system and electrical system. The power and drag reduction system also comprises a plurality of pneumatic motors, one each connected to each wheel, the pneumatic motors using compressed air to drive each wheel and a plurality of electric motors, two each connected to each wheel, the electric motors using electric power to drive each wheel. Based on operator action, the vehicle is propelled by one of compressed air system operation and electrical system operation. Motors associated with each of the compressed air system and electrical system are attached to and drive each wheel separately. The compressed air system and electrical system operate separately and recharge battery systems.

The systems comprise a vehicle that includes a compressed air system and electrical system. The power and drag reduction system also comprises a plurality of pneumatic motors, one each connected to each wheel, the pneumatic motors using compressed air to drive each wheel. The electrical system supports vehicle braking and regenerates electricity for vehicle batteries. A heat exchanger heats expanding air and is configured to substantially evenly distribute said heated air to the pneumatic motors. Air from a front grill is diverted to impellers that turn electric generators to regenerate power and reduce drag. A drag reducing arrangement blending mirrors with camera into the vehicle body is included as is a plug-in 120-volt trickle charge system and a quick charge (DC) system for battery charging.

Pneumatic power and drag system

Embodiments are shown wherein ammonia is used for powering, heating and cooling of various applications including: vehicles (terrestrial, naval, aero-spatial or other engine-driven equipment), residential and commercial buildings, remote generators, refrigerated transport. An ammonia-fuelled internal combustion engine comprising; a thermally insulated fuel tank adapted to store ammonia; a heat exchangers operably connected to the fuel tank, wherein the heat exchanger is adapted to heat the ammonia; a decomposition and separation unit operably connected to the heat exchangers and having a hydrogen conduit and a nitrogen conduit, wherein the decomposition and separation unit is adapted to separate the heated ammonia into hydrogen and nitrogen and stream them into the hydrogen and nitrogen conduits respectively; and an internal combustion engine operably connected to the hydrogen conduit.
