M 43 C – The World’s Number One!

com ponents, low fuel and lubricating oil consump tion as well asextended life be tween main component overhauls – these havebeen the factors most decisive for the M 43’s high acceptancerate.

Power demands in marine propulsion, particularly in the container ship, RoRo ferry and cruise liner markets – as well as new technical solutions for components – were the reasons behind the development of the M 43 C engine.

The re-design concentrated on further improvement through in-creased component operational reliability, further simplificationof maintenance, easier installation and simpler operation. Simpli-fied engine control was also a major consideration. All these factors improved overall economy and are generally advanta-geous to the customer.

As a result, the market now has a high power-density series of engines of 5–9 MW.

Since its introduction to the market, the MaK long-stroke engineseries M 43 has achieved an outstanding position on the marineapplications market as an in-line engine in 6, 7, 8 and 9 cylinderversions. More than 650 engines with a total power of more than6,500 MW have already been sold, making the M 43 the marketleader in the 5–9 MW power class. All the cylinder configura-tions have contributed to this market success. More than 90% of the marine engines run on heavy fuel within IMO regulatorylimits.

The series has been particularly successful in the containerfeeder ship, RoPax vessel, RoRo ferry and cruise liner markets,but M 43 engines have also been installed in fishing vessels andspecialized ships. Whether as a single-engine or multi-engine installation with mechan ical transmission or as a generator driveunit for diesel-electric operation of electric motors, the M 43 has proved itself in service. Features, such as compact modularconstruction with less pipework, easy maintenance access to

M 43 C – Design Features

The turbocharger group consists of a high-performance turbocharger, a cartridge-type air cooler casing andcharge air coolerThe cast charge air cooler casing forms a secure foundation for the turbocharger.The rigidity of the casing and a 40% increase in the base area for the turbo -charger fastening ensure reliable, low vibration operation.

The governor driveis of simple and robust design. Thestraight-tooth gearwheel drive is safeand requires no further adjustment. Designed as a complete module.

Engine with high safety levelThe M 43 C is an engine with a high safetylevel, not only inside in terms of compo-nent life and availability but also with re-gard to external peripheral safety. SOLASregulations are consis tently observed.There is an explosion pro tection cover for the engine block, cladding for thecomplete fuel system from fuel filter to injection pump, while the exhaust gas and turbine casing, including the exhaustgas outlet casing, is in stainless steel – all part of an overall safety concept forthe exhaust gas manifold.

The media duct systemis integrated into the components wherever possible. External pipe work has been reduced to a minimum. Mainte-nance requirements have been cut andwork simplified by plug-in pipe connec-tions.

The turning deviceis of compact construction, safely flangedonto the engine block. An irreversiblegear and an engagement unit en sure simple operation and increased opera-tional safety.

M 43 C – Design Features

Flex Cam Technology (FCT); optionalThe FCT system is a cornerstone of our emission reduction techno logy.Characteristic fuel injection and inletvalve timing are load controlled.

Valve timing changes at part load levelraise effective compression and en-hance complete combustion. In addition,shifting the relative position of the leverto the fuel cam increases injection pres-sure, producing a finer atomization offuel in a load range where it is other-wise difficult to control smoke.

Lower valve drive and injection pump drive“Keep it simple” – this design prin ciple is consistently applied in this component.Of modular construction, the componentis of simple and robust design and boastsincreased operational safety because no ad justment work is necessary.

Control stand with monitoring componentsAll the engine performance data can besimply inspected on a new control standarrangement with reliable, analog dis-plays. The monitoring components arearranged centrally, directly above thecontrol stand. This ensures in creased operating convenience and simplifiedmaintenance.

Cooled injection nozzlesThe design of the cooled injection nozzle provides a number of advantages, particularly during heavy fuel operation.

The engine blockconsists of compact nodular cast ironcomponents. There is a large inspection opening forsideways removal of the crankshaft vibration damper. Increased rigidity hasbeen achieved by means of an integratedpump mounting plate. Fewer componentsmean fewer areas for sealing.

The long-stroke concept for ecological operationEnvironmental protection is also becomingincreasingly important for seagoing ship-ping. Caterpillar Motoren recognized thistrend in good time and, with the design anddevelopment of the modern long-stroke engine concept, created the conditions for engine operation at reduced emissionlevels. The NOx emissions of the M 43C engine lies well below the International Maritime Organisation`s limiting curve.

The long-stroke concept for engine operation at reduced emission levelsThe following features characterise theconcept which ensures, in addition tosmooth running, maximum operational reliability and also permits operation onheavy fuel oil up to 700 cSt /50°C.■ Long piston stroke■ Large stroke/bore ratio■ Intensive injection■ Shaped injection curve■ Optimised control times■ High ignition pressure

For MDO operation the engine is also avail-able with less NOx emission: Det NorskeVeritas DNV “Clean Design” and FederalMinistry of Environment “Blue Angel”.

A further step to reduce soot and emissionsis the introduction of Cat® Common Rail,where the injection pressure is independentfrom load and speed. Utilizing injectionmaps the injection characteristics are opti-mized for every engine operating point. As aresult, NOx and soot emissions are reducedwith the amount of reduction dependent onthe actual engine operating condition.

For areas that are especially emissions-sensitive, soot emissions at low engine load remain well below the visibility limit.Furthermore, during normal load operationNOx emissions can be reduced without influencing fuel consumption. In general, the Cat Common Rail fuel system enablesvessel operation without visible sootthroughout the whole operating range.

Key criteria are: ■ Compliance with current and future

required emission limits for the respective power ranges

■ Customer expectations in terms of engine performance, maintenance practices, fuel quality and mode of operation

By adopting well proven elements of thistechnology for medium-speed engines, it is our goal to meet and exceed customerexpectations by maximizing product valuethrough:■ Superior reliability in heavy fuel

operation■ Best fuel efficiency in its class■ Lowest engine emissions without

additional equipment

Caterpillar Marine Power SystemsSales and Service Organization

The Program: Quality is our MottoFor more than 80 years we have devel-oped, built, supplied and serviced dieselengines – worldwide. Today CaterpillarMarine with its brands Cat and MaK offer high-speed and medium-speed engines with power ratings from 11 kW to 18,000 kW. Many different engine families are available to meet your specific application needs.

Caterpillar has combined the sales andservice activities and responsibility oftheir Cat and MaK brand marine enginebusiness into Caterpillar Marine Power Systems with headquarters in Hamburg/Germany.

In setting-up this worldwide structure, we have concentrated on integrating theCat and MaK brand groups into a single,united marine team, which utilises the particular expertise of each group.

Commercial marine engine business is split into three geographic regions, n Europe, Africa, Middle Eastn Americas n Asia-Pacific,

Cat and MaK diesel engines are distin-guished by high reliability, extremely lowoperational costs, simple installation andmaintenance and compliance with IMOenvironmental regulations.

The application of engines in main andauxiliary marine power systems variesgreatly and extends from high-speedboats and yachts, through tugs, trawlersand offshore vessels to freighters, ferriesand cruise liners.
