Incredible 6-Stroke Water ENGINE?! Bruce Crower
An internal combustion engine and method of operation employing timed injection of water into the combustion chamber for one or a combination of recapturing waste heat, cooling the engine, and lowering Nox emissions of the engine. The water injection subsequent to the power stroke of the engine employs residual heat and heat conducted from surfaces of the combustion chamber, to form steam to drive a second power stroke. The water injection can also be employed to pre-cool the combustion chamber to avoid formation of Nox gases during fuel combustion and by recapturing residual and conductive heat from the combustion chamber the engine is cooled thereby minimizing or eliminating exterior cooling system requirements.

The Crower 6 Cycle Engine
...Bruce has since gone to that race shop in the sky, but not without patenting the basic concepts. It works like this: The standard 4 cycle, (1) intake stroke, followed by (2) compression stroke, (3) ignition and power stroke, and then (4) exhaust stroke (except the exhaust valve stays partially closed). Bruce called it the re-compression stroke. Now, a shot of WATER is introduced into the dense 2,000+ degree combustion chamber, gases causing a steam explosion that creates a second power stroke (5). This is followed by another exhaust stroke (6) and the cycle starts over.
Not only is there a 40% increase in fuel economy, but the super-heated water molecules combine with thems nasty carbon dioxides, carbon monoxides, nitrous oxides, and other oxide baddies to create essentially carbonated water vapor coming out of the exhaust pipe...
Not only does it take advantage of the 1,500-to-one expansion ratio of steam (vs about 10 to one for gas or diesel) but the water injection cools the motor also, eliminating the need for a radiator, fan, water pump, and hoses, with their attendant cost, weight and parasitic drag....

CROWER STEAM-O-LENE ENGINE: From Two-Stroke To Four-Stroke To Six-Stroke; Crower Combines Gasoline And Steam Into One Engine
“One morning I woke up and I knew I had the answer. People don’t know that water expands 1600 times when it goes from liquid into steam. Sixteen hundred! This is why steam power is so good.”
Crower’s Steam-O-Lene engine is a six-stroke engine. Two extra strokes are added to the customary internal combustion engine four-stroke Otto cycle, which makes a six-stroke engine. A third down-stroke is a “steam stroke” and a third up-stroke exhausts the expanded steam while venting heat from the engine. The engine cold starts on the Otto cycle, coasting through the fifth and sixth strokes for a short period. After the combustion chamber temperature reaches approximately 400 degrees Fahrenheit (200 øC), a mechanical operation phases in the fifth and sixth strokes. Just before the fifth stroke, water is injected directly into the hot combustion chamber via the engine’s fuel injector pump, creating steam and another power stroke. The phase change from liquid to steam removes the excess heat of the combustion stroke forcing the piston down (a second power stroke). As a substantial portion of engine heat now leaves the cylinder in the form of steam, no cooling system radiator is required. Energy that is dissipated in conventional arrangements by the radiation cooling system has been converted into additional power strokes. By using steam to power the stroking of the piston, it is assumed that a Crower Steam-O-Lene engine will need to carry and equal amount of water as it does gasoline (distilled water).
