ABSTRACT:
Apparatus and method for improving the fuel economy and noxious emission levels of a gaseous fueled engine by the use of a combustion chamber in a flat topped piston which is smaller in area and deeper than the combustion chamber in a conventional piston. The chamber is offset from the central axis of the piston to cause the squish velocity of the combustion mixture to be high in the vicinity of an ignition device. Also, the chamber is non-circular in shape to create higher turbulence throughout the combustion region.
