From MC to ME



ME Design Basis

•Based on same structural parts and specific

design features as MC design

•Well proven technology from more than 100

years of engine evolution

•Continuous design review due to a large

population of engines, which provide valuable

service feed back

•Future engine development is based on

innovative focus and studies of market demands

and trends.

Utilisation

Engine at low load:

No activation of timing piston

“short cam” early closing of X/V increased Pcomp

Engine at high load:

Activation of timing piston

“short cam” + hydraulic delay delayed closing of X/V

decreased Pcomp

ME Design - Summary

MC/-C

For many years the preferred engine by

the market

• Low production and installation cost

• High reliability

• MC/C cylinder condition

• Cylinder lube amount optimisation

• MC/C extended overhaul intervals

• Experience from more than 15000 engines

• MC/C flexibility in engine programme

• The MAN B&W engine after sales

programme/troubleshooting

ME/-C added value

•Adaptive for continuous updating of the future market

& environmental demands.

•Lower SFOC at Tier II (.2)

•Improved operability and monitoring

•Improved trouble shooting guides

•Rate shaping, fuel injection, NOX balancing

possibilities

•Autotuning, PMI on-line and lifetime saving of

SFOC/LOC

•Integrated Alpha lubricator,

•Low load fuel oil optimisation, ECT

•Integrated electronic control of added equipment

(EGB, TC cut out, VTA, etc.)


What else!

The trend within the shipping industry for operation on lower load and for more fuel and propeller

efficiency has lead to the introduction of a new engine series.

Using the experience from previous long stroke “S-type” engines, a new series of engines has been

launched, the Ultra –Long –Stroke –Engine …

The “G-Type”


The Principles of the G-Series

Ultra-long stroke G-engines are stretched super-long stroke S Mk 9 engines

Low force exhaust valve (ME-

New components• Double wall gas pipes

• Gas injection valves

• Large volume accumulators

• ELGI valves

• Control and safety system

Modified components• Cylinder cover

Simple modifications enable two-

stroke gas injection:

• Proven engine design

• High fuel efficiency ~50%

• High fuel flexibility

• High reliability


ME-GI DesignChain Link Double Walled Gas Supply Pipes


ME-LGI Combustion Principle

The ME-LGI engine is a dual

fuel engine

Diesel combustion process

High effciency

Main injection

Pilot injection


7S50ME-LGI engine >>Top section<< designDesigned for LPG – available from January 2018

The ME-GI is derived from the industry’s standard MC and ME engine.

Diesel cycle high fuel efficiency ~50% versus much lower for other engine types.

High fuel flexibility – burn most LPG grades without derating. Exa. Propane, Buthane, LVOC etc.

High reliability – same as fuel engines.

No derating because of knocking danger.

Negligible fuel slip.

A robust gas combustion – unchanged load response – unaffected by ambient condition
