The Beare Head engine internal combustion engine technology combines a four stroke engine bottom end with a ported cylinder head closely resembling that of a two stroke, thus 4+2= six stroke. The head piston is smaller and has half the speed of the opposing piston. Functionally, the cylinder head piston replaces the valve mechanism of a conventional engine.

“Gentlemen, no one objects to the husband being the head of the wife as Christ was the head of the church—to crucify himself; what we object to is his crucifying his wife.”
—Susan B. Anthony (1820–1906)
