32/40 Four-stroke diesel engine

MAN Diesel & Turbo The responsible way in leading technology

MAN Diesel & Turbo is the world’s leading designer and manufacturer of low and

medium speed engines – engines from MAN Diesel & Turbo cover an estimated

50% of the power needed for all world trade. We develop two-stroke and four-

stroke engines, auxiliary engines, turbochargers and propulsion packages that are

manufactured both within the MAN Diesel & Turbo Group and at our licencees.

More than ever before, MAN Diesel & Turbo’s development focus is the environ-

mental performance of our engines. Using our unrivalled grasp of large engine

technology, we aim to make our engines progressively cleaner, more powerful and

more efficient.

Our absolute commitment to reducing emissions while increasing fuel efficiency

and power density starts with our active partnership in the emissions law making

process and ends with the delivery of engines that achieve an ideal synthesis of

prime mover characteristics.

332/40 – Four-stroke diesel engine

Core technologies in-house

As well as its expertise in engine design, develop-

ment and manufacture MAN Diesel & Turbo is also

a leading manufacturer of the key technologies which

determine the economic and ecological performance

of a diesel engine:

High-efficiency exhaust gas turbochargers

Advanced electronic fuel injection equipment

Electronic hardware and software for engine control,

monitoring and diagnosis

Our impressive array of computer-aided design tools

and one of the engine industry’s largest, best-equipped

foundries allow us decisively to shorten product de-

velopment, and application engineering processes.

Our mastery of these engine technologies – and, the

best brains in the large engine industry – are the firm

foundation for

Low emissions

Low operating costs

Low life cycle costs

Long service life

The range of technical measures employed comprises:

Revised injection timing

Higher compression ratios

Variable Injection Timing (VIT)

Committed to the future

Technologies which promise compliance with the

IMO Tier III emission limits valid from 2016 com-

bined with further optimised fuel consumption

and new levels of power and flexibility are already

under development at MAN Diesel & Turbo.

With this level of commitment MAN Diesel & Turbo

customers can plan with confidence.

RI – Retarded Injection

Retarded injection timing delays combustion heat re-

lease and thus lowers combustion chamber temperature

peaks.

New Piston for Increased Compression Ratio

The use of a new piston provides a higher compression

ratio and gives a faster reduction in temperature after

the ignition of the fuel, thus reducing NOx formation.

The increase in compression ratio also compensates

the reduction in firing temperature due to retarded

injection and hence the associated increase in SFOC.

Efficient, Clean and CompactNOX Reduction measures 32/40

A notable reduction in NOx, CO2 and soot emissions is a strategical factor for success

of modern diesel engines. The 32/40 combined all relevant features to significantly

reduce harmful emissions.

Engine SpecificationsModern and innovative technology

Marine main engines

Engine output is limited to 100% of rated output for

engines driving a propeller. Engine output is limited to

110% of rated output for engines driving a generator.

Overload above 100% permitted briefly to prevent a

frequency drop during sudden load application.

Fuels

The 32/40 engine can be operated on heavy fuel oil

with a viscosity up to 700 mm²/s (cSt) at 50 °C. It is

designed for fuel qualities up to the levels specified in

CIMAC 2003 H/K700/DIN ISO 8217.

Stepped piston

Forged dimensionally stable steel crown (with shaker

cooling) made from high grade materials and skirt in

spheroidal graphite cast iron (skirt also available in steel

upon request). The stepped piston and the fire ring

to gether prevent “bore polishing” of the cylinder liner,

thereby reducing operating costs by keeping lubrica-

ting oil consump tion consistently low. Chromium ceramic

coating of the first piston ring with wear resistant cera-

mic particles in the ring surface results in minimal wear

and tear, ensuring extremely long periods between

maintenance.

MAN Diesel & Turbo turbocharging system

Industry leading designed constant pres sure turbochar-

ging system using state-of-the-art MAN Diesel & Turbo

turbochargers with long bearing overhaul intervals.

High efficiency at full and part loads results in substan-

tial air surplus and complete combustion without resi-

dues and with low thermal stresses on the combustion

chamber components.

Cylinder head

The cylinder head has optimised com bustion chamber

geometry for improved injection spray atomisation. This

ensures balanced air-fuel mixture, reducing com bustion

residue, soot forma tion and improving fuel economy.

Valves

Exhaust valves are designed with armoured, water

cooled seats that keep valve temperatures down. Pro-

pellers on the exhaust valve shaft provide rotation by

exhaust gas, resulting in the cleaning effect of the valve

seat area during valve closing.

Service friendly design

Hydraulic tooling for tightening and loosening cylinder

head nuts; clamps with quick release fasteners and/or

clamp and plug connectors; generously sized access

covers.

Cylinder liner

The precision machined cylinder liner and seperate coo-

ling water collar rest on top of the engine frame and is

there isolated from any external deformation, ensuring

optimum piston performance and long service life.

SaCoSone

All medium-speed marine engines from

MAN Diesel & Turbo are equipped with the SaCoSone

safety and control system. This system undergoes a

workshop test at the factory together with the engine,

ensuring effortless fine tuning and functional testing

during ship commissioning.
