ME-B - System for C/R ・MOP-A（all-in- one PC) ・Keyboard ・MOP-B(all-in- one PC) ・trackball Usual operation is MOP-A MOP-B is backup when MOP-A is broken.

・EICU *Engine Interface Control Unit

Interfacing with outside system (remote controller, safety system, control handle, etc.)

・PMI System PC for PMI Adapter Module *Main Operating Panel

EICU is put in the cabinet.

Measurement and Analysis of the cylinder combustion pressure ※PMI System is standard in ME-B engine 22

ME-B - System for C/R MOP Operation screen

This is MOP’s screen. MOP’s screen had a security system for a chief engineer. In order to adjusts cylinder oil feed rate and fuel oil injection rate, and P-max, The chief engineers need to put password into the screen.

ME-B - System for C/R MOP Operation screen

This MOP operation screen displays the condition of engine. It is possible to check HPS running, pressure, engine speed, scavenging pressure, fuel index, and other functions in this screen. 24

ME-B - System for C/R PMI System (Pressure Analyzer System)

Pressure Sensors

PC for PMI 25

Operation Basically, there is no possibility to adjust except for the 1 cylinder cut running.

1.Select the cylinder. 2.Slowly reduce the Chief limiter.(Adjust and Apply) 3. The finally value to 0.
