Abstract: An air-compressing injection internal combustion engine with a main combustion space arranged in the piston and with an auxiliary chamber equipped with an injection nozzle and with a glow plug, which is in continuous communication with the main combustion space by way of a channel-shaped constriction. The pressure chamber of the auxiliary chamber is thereby disposed eccentrically in relation to the injection nozzle and the constriction while the injection nozzle injects with a first jet into the constriction and with a second jet in the direction or into the area near the glow plug which is located in the eccentrically offset part of the pressure chamber.
