摘要

The two inlet ducts are arranged at least nearly vertical to the symmetry axis to the cylinder bore. At least one approximately half moon shaped recess (3) is located in the piston head (2) of the piston (1). Which lies at least approximately symmetrical to the axis of symmetry. The two spark plugs are arranged in the cylinder bore, which lie at least approximately symmetrical to the axis of symmetry.
