Hydraulic Cylinder Unit (HCU) The Hydraulic Power Supply Unit supplies hydraulic oil to the HCU through double-wall hydraulic pipes. If single-wall pipes are used instead of double-wall pipes, the hydraulic pipes are typically housed within a casing. There are systems with pressures of 300 bar as well as systems with 200 bar. The Hydraulic Cylinder…

Hydraulic System The ME engine’s hydraulic system is an electronically controlled mechanical hydraulic system. The engine control system manages the engine’s fuel oil injection and exhaust valve operation using hydraulic power. The system uses lubricating oil for hydraulic oil and the Hydraulic Power Supply Unit (HPS) provides the necessary hydraulic oil. Hydraulic Power Supply Unit…

Replacing the MPC Card If an alarm goes off on an MPC card, you can read the alarm information from the MOP panel to determine what might be causing the issue. It provides explanations for all possible causes. Some issues and errors can sometimes be resolved by performing a reset. Resetting redundant cards like the…

Auxiliary Control Unit (ACU) There are three ACUs, and they are responsible for managing the Hydraulic Power Supply Pump and the Auxiliary Blower. The ACU operates the start and stop functions of the auxiliary blower based on scavenge air pressure. Additionally, it controls the flow for engine-driven hydraulic pumps and the start/stop functions for electric-driven…

EICU – Engine Interface Control Unit The EICU (Engine Interface Control Unit) is responsible for connecting the Engine Control System with external systems. There are two EICU units installed: EICU A and EICU B. If one unit fails, the other provides redundancy to ensure continued operation. The EICU interfaces with the Engine Remote Control System,…

The MC engines had cam shaft control, which made it difficult to control fuel injection and exhaust valve actuation as desired. With ME engines, instead of cam shaft control, electronic control is used, allowing for more precise adjustments to fuel injection timing and rate, as well as exhaust valve timing and operation. This improved control…
