High-efficiency combustion engines, including Otto cycle engines, use a steam-diluted fuel charge at elevated pressure. Air is compressed, and water is evaporated into the compressed air via the partial pressure effect using waste heat from the engine. The resultant pressurized air-steam mixture then burned in the engine with fuel, preferably containing hydrogen to maintain flame front propagation. The high-pressure, steam-laden engine exhaust is used to drive an expander to provide additional mechanical power. The exhaust can also be used to reform fuel...


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 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...
