Multi-engine system and method for using it

The invention relates to a multi-engine plant and a method for operating said plant, wherein the multi-engine plant comprises a plurality of combustion engines belonging to a functional unit in a driving manner and each combustion engine comprises an adaptive engine control device and at least one sensor that detects operating parameters of the combustion engine, wherein each engine control device is designed to operate the associated combustion engine using operating parameters and to adapt said operating parameters to present operating conditions during operation of the combustion engine by means of optimization, and wherein the engine control devices are signal-connected to each other so that an exchange of information between the engine control devices in regard to the optimizations of the engine control devices is ensured and are each designed to use optimization results of a combustion engine as the basis for the optimization of at least one further combustion engine.
