Abstract
A gas engine has a first fuel feed system, a second fuel feed system and a third fuel feed system. The gas engine is operated by introducing combustion air into a combustion chamber of the engine. In a first mode of operation of the engine, gaseous fuel is added to the combustion air via the first fuel feed system and ignition fuel is injected into the mixture of gaseous fuel and combustion air via the second fuel feed system. In a second mode of operation of the engine, gaseous fuel is added to the combustion air via the first fuel feed system and ignition fuel is injected into the mixture of gaseous fuel and combustion air via the third fuel feed system.

A method of operating a gas engine comprising introducing combustion air into a combustion chamber of the engine and,
- in a first mode of operation of the engine, adding gaseous fuel to the combustion air via a first fuel feed system and injecting ignition fuel into the mixture of gaseous fuel and combustion air via a second fuel feed system, and,
- in a second mode of operation of the engine, adding gaseous fuel to the combustion air via the first fuel feed system and injecting ignition fuel into the mixture of gaseous fuel and combustion air via a third fuel feed system.
A gas engine comprising:
- an air induction means for introducing combustion air into a combustion chamber of the engine,
- a first fuel feed system for adding gaseous fuel to the combustion air,
- a second fuel feed system for injecting ignition fuel into the mixture of gaseous fuel and combustion air,
- a third fuel feed system for injecting ignition fuel into the mixture of gaseous fuel and combustion air, and
- an engine control unit for controlling the second and third fuel feed systems such that in a first mode of operation of the engine, the first fuel feed system adds gaseous fuel to the combustion air and the second fuel feed system injects ignition fuel into the mixture of gaseous fuel and combustion air, and in a second mode of operation of the engine, the first fuel feed system adds gaseous fuel to the combustion air and the third fuel feed system injects ignition fuel into the mixture of gaseous fuel and combustion air.
