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:
“Of what use, however, is a general certainty that an insect will not walk with his head hindmost, when what you need to know is the play of inward stimulus that sends him hither and thither in a network of possible paths?”
—George Eliot [Mary Ann (or Marian)
