MAN ME Electronic Main Engine. Troubleshooting

Greetings! In this article, I introduce the MAN ME electronic main engine, the general concept of MAN ME engines, and examine its individual components — FIVA, ELVA, ELFI, Alfa Lubricator, and Tacho Pickup — as key systems for troubleshooting. As an example, the article examines the MITSUI-MAN B&W 6S50ME-C9.5-EGRBP main engine with an EGR system.

Modern two-stroke, low-speed engines from the ME series by MAN Energy Solutions are fully electronically controlled engines. Unlike mechanical systems, fuel injection, exhaust valves, and cylinder lubrication are controlled by electronic control units via hydraulic actuators.

This article summarizes key information on the main engine systems and troubleshooting algorithms.
