Abstract

In a combustion engine of piston-cylinder type, of the kind which uses preferably homogenous premixed fuel/air mixture and compression ignition, an ignition piston (3) is arranged in the engine's cylinder head (30) and a pushing device (4) is designed to impart to the ingnition piston (3) during the compression stroke of the working piston (2) a movement into the cylinder space (1) in order to control the ignition of fuel/air mixture present.
