Liquid fuel ignited gas engine with emergency operation

A liquid fuel ignited gas engine is proposed that uses, for each cylinder, a liquid fuel system with a specifically configured sole liquid fuel injector for the pilot injection in gaseous fuel operation as well as for emergency operation. The sole liquid fuel injector is configured to allow operating the liquid fuel ignited gas engine in a liquid fuel emergency mode, which provides a power output that is reduced in comparison to the maximum power output in a gaseous fuel mode and that is still sufficient, for example, to maneuver a ship safely into a harbor.
