Beschreibung
Zusammenfassung:	Combustion chamber (2) arranged in the piston (1) of an internal combustion engine is divided by constrictions (7) into at least two subchambers (T). The ratio of the minimum spacing (18) in the region of the constrictions (7) to the maximum spacing (18) in concave areas of the combustion-chamber wall (2'), in each case measured from the axis (10a) of the combustion chamber, is greater than or equal to 0.2. To improve the turbulent flow in the combustion chamber (2), it is envisaged that the ratio of the minimum spacing (18) in the region of the constrictions (7) to the piston radius (22) should be less than or equal to 0.5, the combustion-chamber wall (2') being given a convex shape in the region of the constrictions (7), and that the ratio of the maximum spacing (19) to the piston radius (22) should be greater than or equal to 0.7.
