ABSTRACT:
A combustion chamber in a reciprocating-piston internal combustion engine having at least one inlet duct and at least one outlet duct is formed by a cylinder head and piston each having respective annular squish surfaces for acceleration of fresh gases. A mixture guide element having a recess in its top adjoins the piston crown and the inlet duct to the cylinder is arranged to cause fresh gases to flow with a circulatory movement into the combustion chamber. The configuration increases power output while reducing pollution emissions.
