METHOD OF OPERATING A MULTI-CYLINDER INTERNAL COMBUSTION PISTON ENGINE

摘要

A method of operating a multi-cylinder internal combustion piston engine (10) is proposed. The engine comprises a first fuel feed system (20) and a second fuel feed system (30). While the engine is running, the engine is operated by combusting a second fuel in at least two cylinders. The supply of the second fuel to a first one of the at least two cylinders is stopped, and subsequently the supply of a first fuel to the first cylinder is commenced. Control parameters of a combustion process of the first fuel in the first cylinder are controlled and set to reach predetermined conditions of combustion. The first fuel is supplied to and combusted in the second one of the at least two cylinders, using the previously set control parameters.
