"6-Stroke Engines" Use Waste Heat

"6-Stroke Engines" Use Waste Heat ENGINES Engines 32-5-37 Countless inventors all over the world are trying to use water to make hydrogen they can run in their 2 and 4-stroke engines. Bruce Crower took a different tack. He decided to make an engine that uses petroleum fuel in its first four strokes and water in strokes five and six. Essentiallly, what he does is capture and use engine heat. Crower injects water into the cylinder after the exhaust from the gas ignition strokes is exhausted in the fourth stroke. As the water turns instantly to steam, expanding by a factor of 1600, the pressure carries the cylinder through a fifth stroke with the steam being expelled in the sixth stroke. The effect is to both capture cylinder wall heat for use as power and also to cool the cylinder down. Crower found he could eliminate the normal engine cooling system on the prototype single cylinder diesel he has experimented with. Crower described the benefits of this to Pete Lyons in a December 2006 article in AutoWeek, "Can you imagine how much fuel goes into radiator losses every day in America? A good spark-ignition engine is about 24 percent efficient, i.e. about 24 cents of your gasoline dollar ends up in power. The rest goes out in heat loss through the exhaust or radiator and driving the water pump and the fan and other friction losses." Crowder, an experienced inventor and engineer, was sidelined by health issues recently. His brother David Crower recently told FARM SHOW that Bruce's project is on hold until his return.
