Abstract:
A cylinder head, for an applied-ignition reciprocating-piston internal combustion engine, includes a prechamber ignition system. The prechamber ignition system has a cavity in which an ignition device is arrangeable. The cavity is covered with respect to a combustion space of the reciprocating-piston internal combustion engine with a cover. The cover has at least two apertures which connect the cavity and the combustion space to one another in a gas-conducting fashion. The cavity is divided into a first ignition chamber and a second ignition chamber by a partition, and each ignition chamber is assigned an aperture.
