  It is an object of the present invention to provide a multi-engine facility for each internal combustion engine that optimizes operation to improve speed and quality. Furthermore, this invention is providing the operation | movement method of the said multi-engine installation.

  The object is solved by the multi-engine facility according to claim 1 or the method according to claim 8. Further configurations of the invention are each defined in the dependent claims.

  According to a first aspect of the present invention, there is provided a multi-engine facility having a plurality of internal combustion engines belonging to a functional unit in a driving manner. Each internal combustion engine has an adaptable engine controller and at least one sensor for measuring the rating of the internal combustion engine. Each engine control device is provided to operate the attached internal combustion engine with specific operating parameters and to adapt the operating parameters during operation of each internal combustion engine to the current operating conditions of the internal combustion engine by optimization. It has been. Since the engine control devices of the internal combustion engine are connected to each other by a signal, information exchange between the engine control devices regarding the optimization of the internal combustion engine is guaranteed. Each is provided for optimizing at least one further internal combustion engine of the plurality of internal combustion engines based on the result of the optimization of one of the internal combustion engines.

  Since the engine control device of each internal combustion engine is networked based on the present invention, the optimization results can be exchanged with each other. Therefore, in the multi-engine facility according to the present invention, each internal combustion engine The optimization of the operation with respect to speed and quality is improved.

  In other words, the “experience” of the internal combustion engine is transmitted to one or more other internal combustion engines of the multi-engine facility by exchanging information between the internal combustion engines in the multi-engine facility according to the present invention. The plurality of other internal combustion engines are optimized in operating behavior.

  According to one embodiment of the present invention, an internal combustion engine that is in operation and whose engine controller is optimized for operating conditions such as, for example, existing fuel and ambient conditions is the result of the optimization. Can be transferred to one or more remaining internal combustion engines of a multi-engine facility that are in standby or have not yet reached the operating status of the first listed internal combustion engine.
