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:
“If I were as I once was, the strong hoofs crushing the sand and the shells,
Coming out of the sea as the dawn comes, a chaunt of love on my lips,
Not coughing, my head on my knees, and praying, and wroth with the bells,
I would leave no saint’s head on his body from Rachlin to Bera of ships.”
—William Butler Yeats (1865–1939)
