Abstract
A piston crown is formed with cavity a which includes a first flame deflecting member which divides the flame ejected from a transfer port interconnecting a swirl chamber with a main combustion chamber while the piston is relatively close to its TDC position and a second flame deflecting arrangement which divides the flame flow after the piston has descended by a given amount. The stage deflections of the flame promotes extensive dispersion thereof and the formation of a flame plume which engulfs a relatively large amount of the air in the combustion chamber and improves mixing of the burning gases and unburnt fuel with the air in the combustion chamber.
