Power and performance.MAN engines for vehicles.

From Rudolf Diesel to Common Rail Diesel. Rudolf Diesel would have wholeheartedly approved. The great

inventor, who developed the fi rst diesel engine through to series-

production maturity at MAN between 1893 and 1897, would be

amazed at MAN‘s present-day engines and the progress they

embody. MAN‘s engines for vehicles demonstrate competence

in every aspect of technical progress: power ratings that set

standards; innovative engineering such as Common Rail injection

which points the way as regards dynamics and economy; the

latest technology to guarantee compliance with Euro 4; and the

proverbial reliability that continues to write new chapters in the

success story of MAN engines.

The best thing to do is to experience progress for yourself. Take

a look at MAN‘s diesel and gas engines for trucks and buses and

enjoy the additional input from our comprehensive advisory and

other services. If you have something big to move, just trust MAN.

Every successful vehicle is driven by a successful engine.

MAN engines – innovation and reliability.

For coaches, buses or trucks, from light to heavy: with an MAN

engine inside you‘ve got more going for you. Take advantage of

the power and dynamics of our D08 engine that drive our TGL

and TGM trucks. Or feel the thrill of the power from our D20/D26

engines. Both engine ranges will of course get your vehicles

moving too. Equipped with Common Rail injection, four-valve

technology and exhaust-gas recirculation, all MAN engines have

one thing in common: they display superb power development,

economy and environmental compatibility. In other words that

means high effi ciency. All Euro 4 engines are available with on-

board diagnosis (OBD1) as required by law.

D08 Common Rail: Today driving is so economical.

In-line power.

Four and six cylinders, 110 to 240 kW – or D08 for short.

Whichever engine from this range you look at, you‘ll discover

new top performance. The EDC7 electronic control system that

supplies the data for the Common Rail injection, ensures more

effi ciency, a higher torque and a higher power output. Almost all

engines feature two-stage supercharging; only the 110 and

176 kW engines for trucks have one-stage charging. The most

powerful models have a wastegate on the turbocharger. All

engines have the EVB (exhaust valve brake) as a series feature:

it provides high brake power, protects the service brake, saves

wear, cuts the running costs and provides extra safety.

Coming clean.

One attractive aspect of the engines is the extremely low pollutant

emissions to Euro 4. The D08 engines are not only fascinating as

far as power, economy and environmental compatibility are

concerned, but discreetly quiet as well. Their compact but robust

design will win you over too.

D20/D26 Common Rail: Putting innovation in motion.

Power to move big vehicles.

The latest chapter on future-orientated diesel engines is entitled

D20/D26. This is the most modern engine range in Europe with

common-rail injection, four-valve technology, exhaust-gas

turbocharging, air/air intercooling and cooled external exhaust-

gas recirculation and the EVB engine brake. Outstanding in its

power and quietness, environmental compatibility, effi ciency and

economy, these six-cylinder units put considerably more force

behind your success. The D20/D26 engines get more power out

of the fuel and consume approx. 5 % less diesel. They‘re low on

weight too, about 100 kg lighter than their D28 predecessors. On

the exhaust front they are lastingly cleaner than Euro 4 requires,

and in terms of noise they are so quiet that you hardly notice them.

A whole series of typical qualities go to show how reliable the

D20/D26 engines are:

n Extremely rigid crankcase made of special GJV 450 cast iron

n One-piece cylinder head with cast-on intake pipe, integrated

(overhead) camshaft and easy-action roller rocker arms

n Compact fuel and oil supply modules

n Separate coolant and lube oil supply to crankcase and cylin-

der head; this makes it possible to use a single cylinder head

gasket for all cylinders without coolant and lube-oil passages.

n etc. etc.

Making light of things.

Sometimes more is achieved if certain things are dispensed with:

the D20/D26 comes with about 25 % fewer parts than its

predecessor, the D28. This makes it some 100 kg lighter, and its

weight-to-power ratio is accordingly higher. It also has fewer

sealing points. As a result the D20/D26 range is the clear leader in

terms of service life and reliability. Built for around 1.5 million km,

it outclasses the D28 by about 50 %.

Fewer services.

In the D20/D26 “maintenance-friendly“ doesn‘t mean just easy

access to service points but extremely long service intervals too.

The D20/D26 can cover up to 120,000 km before the next service

is due. That gives you plenty of time to leave competitors

standing.

D20 power in the horizontal.

Engines for underfl oor installation

MAN offers several engines from the D20 range as horizontal

versions too for installation under the fl oor of buses. Their ratings

range from 199 to 316 kW.

All that gas.

MAN offers the natural-gas engine for scheduled-service buses

in two variants: a 12 l induction engine with 3-way catalyst and

rating of 180 kW, and a 12.8 l lean-mix turbocharged unit with

intercooling and 228 kW specially designed for powering articula-

ted buses. As in petrol engines, in natural-gas engines the power

output is controlled by a butterfl y valve and combustion is initiated

via sparkplugs. The gas tanks are mounted on the roof of the

vehicle. MAN also has a 12.8 l liquefi ed-gas engine to offer, the

G28. An induction engine with 3-way catalyst, it has an enticingly

high torque and supplies 200 kW.

Today the emissions from MAN gas engines are already well

below the limits stipulated by the Euro 5 standard and the even

stricter EEV (Enhanced Environmentally Friendly Vehicle). Their

noise emissions are low too.

E28/G28 gas engines – the clean alternative.

Everything that‘s good.

MAN‘s Euro 3 engines for markets outside Europe are state of the

art. With Common Rail injection, four-valve technology and cooled

exhaust-gas recirculation the D08, D20 andD28 engines are

convincing in their power development, cultured in their running

and low in fuel consumption.

A clean break for the future.

Progress goes on.

Diesel exhaust emissions are becoming cleaner and cleaner. The

Euro 4 limits – in force since October 2005 – brought another

major reduction in pollutant emissions. Euro 5 will be following in

October 2008 – another great step towards a clean environment.

MAN provides innovative exhaust-gas technologies that both

meet future requirements and are perfectly tailored to customers‘

requirements.

EGR and MAN PM-KAT®.

With the system consisting of Common Rail injection, cooled

exhaust-gas recirculation (EGR) and the MAN PM-KAT® parti-

culate fi lter MAN has a technically and economically convincing

solution for Euro 4. Cooled exhaust-gas recirculation (EGR)

makes it possible to reduce the proportion of oxides of nitrogen

(NOx) to extremely low levels inside the engine. To comply with

the particulate limits the PM-KAT® is used. This is a maintenance-

free particle trap system in the special-steel silencer that works

without clogging and needs no additional agent. The PM-KAT®

eliminates an above-average share of the smallest particles; its

separation rate is about 70 %.

Clean advantages with MAN PM-KAT®

n Reliable, maintenance-free system that works without

clogging

n No restrictions on space for other components

n Up to 150 kg weight advantage on other exhaust-gas

cleaning systems

n Above-average elimination of the smallest particles

MAN AdBlue® .

To comply with Euro 5 even today MAN offers SCR (Selective

Catalytic Reduction) technology under the name of MAN AdBlue®.

In this process the oxides of nitrogen are reduced in a down-

stream ceramic catalyst, the SCR CAT. The process needs the

reducing agent AdBlue®, a non-toxic, odourless urea solution.

It is sprayed into the fl ow of exhaust gas and then converts the

oxides of nitrogen into water vapour and elementary nitrogen –

a natural constituent of the air – in the catalyst. This technology

achieves NOx reduction rates of over 80 %.

CRTec® particulate fi lter.

For use in buses MAN can as an option also equip various

engines with the CRTec® (Continuously Regenerating Trap)

particulate fi lter, which reduces the particulate emission to the

Euro 4 levels. This fi lter system is electronically controlled and

self-regenerating, but not maintenance-free. To ensure that

the necessary exhaust-gas temperatures are available for an

optimum regeneration process, the CRTec® fi lter is linked to the

EDC7 engine electronics. A display tells the driver when the fi lter

needs maintenance.

One of the few alternative fuels to have met with acceptance

today is natural gas. If the mobile fuel used is gas, the engine

emissions achieved are excellent. The problems are encountered

in the higher price of the vehicle and the build-up of a national

supply network. Today the emissions from the natural-gas and

liquefi ed-gas engines (CNG, LPG) developed by MAN are already

below those laid down by the Euro 5 and EEV standards. These

full carbon winding. Depending on vehicle deployment, this en-

sures an operating range of 150 to 250 km.

The MAN hydrogen engine emits exhaust gases with pollutants

well below the limits stipulated by the EU up to Euro 5 and consi-

derably betters even the EEV (Enhanced Environmentally Friendly

Vehicle), currently the strictest exhaust-gas standard introduced

to date.

Gas engines to speed up progress.

Hydrogen has a future.

Hydrogen meets the requirements for a mobile fuel of the future.

It could put an end to the dependence on fossil fuels and to the

global warming caused by carbon dioxide emissions. We are

currently working hard on further development of this hydrogen

technology with a view to introducing it into series production in

due course. It has been successfully proved that hydrogen can be

used in MAN buses. The vehicles are powered by a 12.8 l engine

rated at 150 kW and equipped with a blow-in and spark injection

system. The gaseous hydrogen is carried in a gas storage system

on the roof of the vehicle. This consists of aluminium tanks with

Alternative drive systems. Innovations from MAN.

are 6-cylinder horizontal in-line engines which are available as

naturally aspirated units with 3-way catalyst (lambda = 1) or as

supercharged and intercooled lean-mix engines (lambda = 1.7).

They develop power outputs of 180 to 228 kW. Because of

their soft combustion the MAN gas engines also have low noise

emissions.

Powerful back-up too. MAN services.

MAN components for vehicles.

MAN offers engines and individual components, all of them practice-

proven components from MAN‘s truck and bus programme:

n Steered front axles

n Planetary and hypoid rear axles

n Leading and trailing axles

n Transfer cases for all-wheel-drive vehicles

All individual components are perfectly matched to each other.

MAN Service.

MAN‘s motto is proximity to markets and customers. Through-

out Europe some 1,200 MAN outlets ensure full presence.

Competent staff who undergo regular training provide MAN

customers with qualifi ed advice and fast, expert maintenance

and repair – if necessary via the mobility service Mobile24.

MAN parts management.

MAN‘s central spare parts organisation guarantees a reliable

supply of parts to the service outlets, the basis for this being a

well-stocked parts store and the latest logistics. In emergencies

genuine MAN parts can be supplied even more quickly – the

MAN express parts service delivers them round the clock.

MAN quality – through and through.

Over 100 years of experience and expertise in building engines

form the basis for the outstanding reputation of MAN engines.

They are reliable, environment-friendly and economical – and

frequently cover well over 1 million kilometres. The aim is to

achieve 100 % quality, and to this end MAN uses a sophisticated

quality management system certifi ed to DIN EN ISO 9001.
