Engine having prechamber ignition and method of controlling such an engine

An engine (1) comprising prechamber ignition, in particular a gas engine, comprising:

• a main combustion space (2) in a cylinder of the engine (1) for combusting an air-fuel mixture;
• and
• a prechamber (3) having an ignition device (4) projecting into it and a fuel injector (5) projecting into it,
• wherein the prechamber (3) has at least one transfer point (6) that fluidically connects the prechamber (3) to the main combustion space (2),
• the fuel injector (5) projecting into the prechamber (3) is the only fuel injector (5) via which fuel can be introduced into the associated main combustion space (2), and
• the fuel is hydrogen or contains hydrogen as the main component or as an admixture or it is a fuel similar to hydrogen or it is another fuel that has an ignition capability for lambda above 2.5 and particularly preferably an ignition capability for lambda equal to or above 3 and very particularly preferably an ignition capability for lambda equal to or above 5.
