Abstract (en)
[origin: DE19848649A1] A carbon piston engine having a lower side (112) that forms a domed surface, preferably an ellipsoid surface, in the area between the enlargements of the hub (151) irrespective of the design of the lower side of the piston head, whereby said domed surface is adjacent to the enlargements of the hub. The skirt (104) of the piston has an axial profile in the form of a conical surface with straight-line generatrixes, tapering upwards as it comes into contact with the ring section.
