Summary

MAN B&W ME-C series. Summary

The advantages of the ME-C range of engines are quite comprehensive, as seen below:

  1. lower SFOC and better performance parameters thanks to variable electronically controlled timing of fuel injection and exhaust valves at any load
  2. appropriate fuel injection pressure and rate shaping at any load
  3. improved emission characteristics, with lower NOx and smokeless operation

Features of ME-C engines

As mentioned in the introduction, the purpose of making electronic engines is focused around the virtues related to “ensuring fuel injection and rate, as well as exhaust valve timing exactly when and as desired”.

The mechanical difference between an MC-C engine and its electronically controlled counter-part, the ME-C engine, constitutes a number of mechanical parts made redundant and replaced by hydraulic and mechatronic parts with enhanced function, and summarised below.

Introduction

MAN B&W ME-C series. Introduction

The introduction of the electronically controlled camshaft-less low speed diesel engines, which is now gaining momentum, is a milestone in diesel technology that deserves a place in history like Rudolf Diesel’s first engine in Augsburg, the 1912 motor vessel Selandia, the introduction of turbocharging on two-stroke diesels in 1954, and the first SCR (Selective Catalytic NOx Reduction) systems on ships in 1989.
