Abstract
A method of driving a piston ( ) of an internal combustion-engined tool having a combustion chamber which is separated by a separation plate ( ) with a plurality of through-opening ( ) into a fore-chamber section ( ) and a main chamber section ( ) adjoining the piston ( ), including producing gas jets having a predetermined energy, which enter the main chamber section ( ) through the through-openings ( ) of the separation plate ( ), combusting, in the fore-chamber section ( ), at least approximately a volume of a combustible gas mixture corresponding to the pre-determined energy of the gas jets, and combusting, in the main chamber section, a combustible gas mixture for creating a pressure necessary for displacing the piston.
