Zusammenfassung:	A combustion system includes a cylinder having a main chamber and a fuel injector positioned to inject fuel into the main chamber. A cylinder head is disposed at a top of the cylinder and forms an upper end of the main chamber. A prechamber adapter has a prechamber volume and a nozzle with a plurality of orifices for communication between the prechamber volume and an external environment. The prechamber adapter is threaded into a bore in the cylinder head and positioned to expose the nozzle to the main chamber. A spark plug is positioned within the prechamber adapter with a spark emitting end exposed to the prechamber volume. A piston movably disposed within the cylinder has a piston head forming a lower end of the main chamber. The piston head has a dome shape and a bowl formed in a top center of the dome shape.
