To prevent engine damage through hydraulic impact due to excessive oiling of the combustion chamber, the
engine must be started at least once a month as a countermeasure.
Electronic system
Electronic control and monitoring system with integrated safety and test system, providing interfaces to Re-
mote Control System (RCS) and Monitoring and Control System (MCS).
Engine Interface Module (EIM)
The Engine Interface Module (EIM) is the central connection box on the engine. It covers the complete mini-
mum scope of a marine engine. It does not have any controls or components requiring maintenance.
Functions:
• Starter control (start repetition, tooth alignment, starter protection)
• Battery-charging generator monitoring
• Open bus interface to the plant (SAE J1939)
• Emergency stop function with wire break monitoring
• Redundant power supply
• Optional control of emergency-air shutoff flaps
• Key switch logic
• Interface to ECU and EMU
• MCS5 dialog interface
• Control of an MTU lube oil priming pump (power components in separate MTU PPC Box)
• Connection facility for an MTU Local Operating Station (LOS)
Serial RS422 interface for diagnosis
The engine interface comprises two parts. The first section is integrated in the engine cable harness via a
Tyco male connector X52, 62-pin. The second part refers to signals associated with higher currents. These
signals are guided out via M-threaded pins and are also integrated in the engine wiring harness.
Functions
• Power supply of ECU
• Power supply of EMU
• Plant signals (ECU7 connector X1)
• Bus interface (2x MCS5 CAN)
• CAN dialog output (1xMCS5 CAN)
• Emergency stop from EMU and ECU
• Electric starter
• Terminal 45 starter A/B (engaged)
• Pneumatic starter
• Starting-air pressure valve
• Starting-air pressure sensor
• Barring gear (Barring Gear 1 and 2)
• Battery-charging generator (with exciter control)
• Optional emergency air-shutoff flaps
• Activation of emergency-air shutoff flaps 1+2
• Feedback from emergency-air shutoff flaps 1+2
Electronic engine governor (Engine Control Unit, ECU)
Functions:
• Engine speed control with fuel and speed limitation according to engine status and operating conditions
• Control of sequential turbocharging, cylinder bank cut-out and air recirculation function
• Data processing logistics for analog and binary signals
• Interface for data transfer to CAN field bus for remote control and ship-side monitoring
