Abstract

See full text

A spark ignited engine is disclosed. The spark ignited engine includes a main combustion chamber and a cylinder head at least partially surrounding the main combustion chamber. A spark plug having a central axis is arranged in the cylinder head and an ignition end of the spark plug faces the main combustion engine. A pre-chamber with at least two nozzles is arranged in the main combustion chamber and connects the ignition end and the main combustion chamber via the at least two nozzles. A pre-chamber volume ratio corresponds to a ratio of a volume of the pre-chamber to a volume of the main combustion chamber at a top-dead-center and is between 1.9% and 3.1%. A nozzle factor corresponds to a ratio of a summed flowed-through area of the at least two nozzles to the volume of the pre-chamber and is between 0.085 l/cm and 1.15 l/cm.
