Abstract

The eccentrically located combustion chamber 9 in the piston 3 has substantially flat sloping side walls extending between the approximately eliptical opening 12 and the substantially flat approximately eliptical chamber bottom 11. The regions 18 and 18a of the piston head about the opening 12 approach the facing flat cylinder head surface to provide squish. A spark plug 20 and valve controlled inlet and exhaust ports 5 and 6 are located in the cylinder head (1), Fig. 1 (not shown), over the opening 12.
