Wärtsilä engines are delivered with the UNIC embedded engine management system.

The UNIC system is designed to ensure extended lifetime for large marine diesel and gas engines operating in the toughest of conditions. Special attention has been paid to temperature- and vibration endurance throughout the design, while the highest priority has been given to operational reliability.
 

Key features of the UNIC system include the engine safety system, local monitoring, speed control with loadsharing, fuel injection- and timing control, knock detection, alarm signal acquisition, start/stop sequencing, load reduction request, system diagnostics, and a fieldbus interface as applicable for each engine configuration.

Thanks to the electronic control, the engine can be adapted to different operating conditions. Furthermore, the pre-tested configuration allows the engine or generating set to be made ready for operation with a minimum of commissioning and installation work.
