Abstract:
1. A combustion engine power system comprising: a combustion chamber which burns a fuel with a pressurized mixture of steam and air to generate useful power and waste heat, the combustion chamber producing a steam-containing exhaust stream; a power take-off of the useful power from the combustion chamber; a compressor in fluid communication with the combustion chamber, the compressor pressurizing air to produce a pressurized air stream; a water supply in fluid communication with the pressurized air stream, at least a portion of the water from the supply being heated by waste heat from the power system and evaporating into the pressurized air stream to produce the pressurized mixture of air and steam; an expander in fluid communication with the combustion chamber, the expander being driven by the steam-containing exhaust stream to produce a power output in excess of the power required to pressurize the air; and a power take-off of the excess power from the expander.
