Bruce Crower has made a name for himself with his aftermarket performance parts business Crower Cams, but at 75 years old Crower may have done the most remarkable thing in his life. Crower has developed a six-stroke engine that may just forever change the automotive world.
Using a modified single-cylinder diesel engine Crower converted it to use gasoline, then machined the necessary parts to create the worlds only six-stroke engine. The engine works through harnessing wasted heat energy created by the fuel combustion to add another two-strokes to the engine cycle. After the combustion stage water is injected into the super heated cylinder and steam forms forcing the piston back down and in turn cools the engine. The result is normal levels of power using much less fuel and no need for an external cooling system.
Crower is now trying to develop a working diesel version of the motor which he feels will be even more efficient and could see the most promising usage in semi truck applications where huge amounts of fuel are wasted in the cooling systems for large trucks.
Much more testing is needed to be preformed on the six-stroke motor but at this early stage it looks as if it could be a very promising power plant for the future saving both on fuel costs and proving more beneficial to the environment.
