Which system performs engine protection and self-diagnosis functions on the RB-M 45?

The DDEC (Digital Diesel Engine Control) system is specifically designed to monitor and manage the performance of the RB-M 45’s engines. It provides critical functionalities, including engine protection measures and self-diagnosis capabilities. These functions enable the system to detect and respond to various engine parameters, ensuring the engine operates within safe and efficient limits.

Engine protection is crucial because it helps prevent damage from conditions such as overheating, over-speed, or low oil pressure. The DDEC system continuously monitors these parameters and can take corrective actions or alert the operator if a fault is detected. Additionally, the self-diagnosis feature allows for real-time assessment and troubleshooting, which is vital for operational readiness, as it informs the crew of any potential issues before they become critical.

In contrast, the other systems mentioned are responsible for different operational aspects. The transmission control system manages power transmission from the engine to the drive systems but does not inherently include engine protection or diagnostic functionalities. The A/C control system governs the climate control within the vessel, while the navigation system is focused on positioning and route planning. Each of these plays a distinct role but does not encompass the engine monitoring and protective capabilities integral to the DDEC system.
