Engine control system architecture.
The backbone of each X-engine is an autonomous Engine Design Control System. The system is designed to serve specific needs of a low-speed common-rail diesel and dual-fuel engine.
The Engine Control System (ECS) architecture gives not only high level of redundancy, which is required by Classification Societies, but additionally user friendly features like automatic software download in case of module replacements and a clear
and comprehensive Operator Interface.
ECS control modules are located in a separate part of the Rail Unit allowing the shortest possible cable connections to most of the control elements and sensors. This ensures uncompromised electromagnetic compatibility and economical and clear wiring.
The Rail Unit cabling is completed during the pre-fabrication of the Rail Unit. Depending on design, some engines benefit from the integrated power supply concept, which offers an even more compact solution with all of the AC/DC power supply modules located directly in the lower part of the Rail Unit.
The communication of the Engine Control System with the Propulsion Control System (Remote Control System + Safety System + Alarm Monitoring System) is facilitated via redundant CAN / ModBus systems.
In accordance with the Classification rules, the ECS is able to control the engine alone, even in the case of a Remote Control System failure. The architecture of the X-engines’ control systems allows flexible and seamless integration with IMO Tier III solutions (SCR, EGR, etc.) and with various versions of waste heat recovery systems, external data acquisition and diagnostic systems.
The commissioning procedure of the ECS at the engine manufacturer and on-board the vessel has been optimised for fast, efficient with user friendly commissioning. Software tools offer parameter settings and trending and advanced trouble shooting options.
