ABSTRACT:
A spark-ignited reciprocating-piston internal combustion engine is provided with a combustion chamber subdivided in the top dead center zone into two chambers. These two chambers are separated from one another by overlapping parts of the piston and cylinder and cylinder head when in the top dead center zone, such that when in this position a cross-connection between the chambers exist only at one position along the circumference of the piston. An ignition source is provided adjacent one circumferential end of a first of the chambers which forms a combustion duct between the ignition source and the cross connection. The ignition is controlled so as to take place only after the piston and cylinder are in respective positions separating the combustion chamber into the two chambers.
