ABSTRACT:
In an internal combustion engine with spark ignition and one or more reciprocating pistons, with an ignition device and at least one fuel delivery device for each cylinder, and with a combustion chamber bounded by a roof-shaped top face, the surface of the piston top is provided with an unsymmetrical, arched flow guiding rib assisting the swirl movement of the cylinder charge. The flow guiding rib is configured as an integral part of the piston top surface, which largely conforms to the roof-shaped top of the combustion chamber, and includes an essentially centrically positioned combustion chamber recess with an entrance area in close proximity of the fuel delivery device.
