- 16/03/2006, Influence of Ambient Temperature Conditions
- Two-stroke diesel engines used as prime movers in ships are exposed to the greatly varying climatic temperature conditions that prevail in different parts of the world and must therefore be able to operate under all ambient conditions from winter to summer and from arctic to tropical areas.
- 26/11/2005, Operation on Low-Sulphur Fuels Two-Stroke Engines
- The average sulphur content of fuel oil used for marine diesel engines is 2.7%. This will undoubtedly change with the coming emission legislation, which will lower the emission limits of SOx, NOx, particulate, HC and CO.
- 19/07/2005, Thermo Efficiency System
- Following the trend of required higher overall ship efficiency since the first oil crisis in 1973, the efficiency of the main engines has increased and, today, the fuel energy efficiency is about 50% This high efficiency has, among others,led to a correspondingly lower exhaust gas temperature after the turbochargers.
- 20/05/2005, ME-GI Engines for LNG Application System Control and Safety
- Until the end of 2004 there was still one market for ocean-going cargo ships to which the two-stroke engine had not yet been introduced: i.e. the LNG market. This market has so far been dominated by steam turbines, but the first orders for two-stroke diesel engines were given at the end of 2004. Today, 16 ME engines to LNG carriers have been ordered for eight LNG carriers, which are to be built in Korea, Ref. [1].

- 01/09/2004, Emission Control MAN B&W Two-stroke Diesel Engines
- The worldwide focus on fuels is generally increasing because of the focus on exhaust gas emissions. During more than 10-15 years, the authorities have been focused on establishing rules for the exhaust gas emissions from marine engines, and today it seems that IMO Annex VI will be ratified in the course of 2004/2005. Hence, the marine industry will be under international regulation.
- 16/08/2004, The all-in-one Diesel Service

- 22/04/2004, Soot Deposits and Fires in Exhaust Gas Boiler
- The demand for the highest possible overall fuel efficiency is reflected in developments over the last two to three decades in the propulsion market for oceangoing ships. Today, this market is dominated by highly efficient two-stroke low speed diesel engines which run on low quality fuels and utilise (recover) the exhaust gas heat by means of an exhaust gas boiler/economiser.
- 22/04/2004, Basic Principles of Ship Propulsion
- Today, the primary source of propeller power is the diesel engine, and the power requirement and rate of revolution very much depend on the ships hull form and the propeller design. Therefore, in order to arrive at a solution that is as optimal as possible, some general knowledge is essential as to the principal ship and diesel engine parameters that influence the propulsion system.
- 02/04/2004, LNG Carrier Propulsion by ME-GI Engines
- LNG carriers represent the last stand for the in all other markets practically extinct marine steam turbines. With efficiencies of only about 30%, versus the diesel engines more than 50%, and in combined systems even higher, diesel engines are the propulsion system of choice in the marine industry.
- 09/12/2003, Crankcase Explosions in Two-stroke Diesel Engines
- It is generally recognized that the two-stroke diesel engine is the most economical and reliable prime mover, and MAN B&W Diesel always gives high priority to a conscientious development of the product and to providing important information to our customers, to ensure an even higher level of reliability.

- MAN B&W Diesels two-stroke low speed diesel engines and MAN B&W Holeby four-stroke diesel GenSets are designed to operate in accordance with the unifuel principle, with the same fuel for both main and auxiliary diesels.
- 25/06/2003, ME-Engines - the New Generation of Diesel Engines
- 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.
- 25/06/2003, LNG Carrier Propulsion by ME Engines and Reliquefa
- LNG carriers represent the last stand for the – in all other markets – practically extinct marine steam turbines. With efficiencies of only about 30%, versus the diesel engines' more than 50%, and in combined systems even higher, diesel engines are the propulsion system of choice in the marine industry.

- After a highly successful experience with the prototype 6L60MC/ME engine, Odfjell ASA, Norway, commissioned the World’s first dedicated ME engine, a 7S50ME-C, from MAN B&W Diesel’s Frederikshavn Works.
- 09/04/2003, Maintenance and Safety Aspects
- When designing a new engine type, the maintenance and service aspects are of great importance, Fig. 1. The safety aspects are of importance during the production, assembly, testing and installation of the engines at the licensees and the shipyards and, naturally, it is also of importance when the ship enters service.

- The Alpha Lubricator System, Fig. 1, available for all MAN B&W MC/MC-C two-stroke engines, has an algorithm controlling cylinder oil dosage proportional to the sulphur content in the fuel. This algorithm is referred to as Alpha Adaptive Cylinder-oil Control (Alpha ACC).
- 09/04/2003, Lubricator System for Cutting the Cylinder Oil
- The cylinder lube oil consumption represents a large expenditure for an engine operating with the nominal guiding feed rate and, especially for the large bore engines, even a 0.1 g/bhph reduction in the cylinder oil dosage represents a significant yearly saving for the owner.
