Abstract
A piston has formed in the top thereof a part-spherical depression which forms part of a combustion chamber. The depression is so formed as to permit the flame front during the initial stage of combustion to reach the surface of the depression substantially at the same time, giving better conditions for efficient combustion and short combustion duration.
