Abstract
A piston is arranged for reciprocal movement in a combustion engine cylinder. Protrusions are or a ridge is arranged half way between flame plume impingement areas in a plane perpendicular to the reciprocal movement and protrude to the combustion chamber having a smooth form adapted for preserving kinetic energy in a flame plume. The protrusion or ridge includes a left side flank, a top section and a right side flank, and a transition section between each of the side flanks and the top section, the transition section including a deflection edge in order to minimize flow losses.
