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.
Famous quotes containing the word head:
“Embraces are cominglings from the head even to the feet,
And not a pompous high priest entering by a secret place.”
—William Blake (1757–1827)
