Dear Reader

In Western Europe, diesels have long been a success story. More than

50 percent of all new passenger cars sold here are now diesels, and in

many countries that proportion is over 70 percent.

And for good reasons: diesel engines offer considerable savings in fuel

consumption and their high torque provides a noticeably enhanced per-

formance. This delights the driver as much as it benefits the environment.

Reducing CO emissions by a quarter lightens the load for all of us.

You profit from the benefits of diesel even if you do not drive one your-

self. Think about all the diesel vans, trucks, construction and agricultural

vehicles around you. Everywhere, diesels are doing their jobs reliably

and economically.

At Bosch Diesel Systems, we are continuously improving diesels, making

them more economical, more powerful and environmentally friendly.

A diesel hybrid, for example, combines the benefits of the diesels reduced

fuel consumption and CO emissions with the advantages of electric drive.

Modern exhaust-gas treatment reduces emissions to a minimum and

makes diesels clean.

On the following pages, you will find some interesting facts about diesel.

As you will see, you are more involved with todays diesel and our future

with Clean Diesel than you might think.

Will dieselsave the world?

Answering this question with yes might perhaps be an overstate-

ment; yet, diesel does offer solutions to problems which plague

politicians, societies and economies the world over. The important

questions of our day and age such as climate protection, the finite

nature of fossil fuels or globalization and its co nsequences each

raise countless challenges. Challenges which at first sight seem

unconnected with diesel. But it is well worth taking a second look,

as you will now see for yourself.

CleanThe big bangcreatedby modern compressionignition

The Common Rail System, put into serial production by Bosch

in 1997, marks the moment that the modern diesel powertrain

came to be as we know it today. Imagine the weight of a 2,000-kilo

rhinoceros standing on your fingernail. This ought to give you a

clear impression, in the truest sense of the word, of the pressure

to which the system compresses the fuel before injecting it at

a supersonic speed into the combustion chamber as a finely dis-

tributed spray, thus ensuring particularly clean and economical

combustion combined with a maximum amount of driving fun.

Tomorrows solutionswill not prevent the COemissions of today

Electromobility is the way of the future. But when exactly will that

future begin? The internal combustion engine will dominate for the

next 20 years at least. Therefore, anyone who wants to improve our

carbon footprint today can only achieve this with combustion engines,

which is where diesel vehicles come into play because they emit

around 25 percent less CO than a comparable gasoline model.

Thus, the CO emissions of a diesel today are already at the same

level as those of gasoline hybrids. The technology needed to achieve

this is also comparatively less complex.

That which is good can always be better. This means that the diesel

vehicles of 2020 will co nsume around a third less fuel and emit a

third less CO than today. This will depend on measures such as

start/stop systems and downsizing just as much as it will on low-

friction tires, lightweight construction and the reduced atmospheric

resistance of the vehicles. All in all, this means that diesels will

certainly be able to fall below the future limit of 100 grams of CO

emissions per kilometer. This corresponds to fuel consumption of

less than four liters per 100 kilometers.

Its not a trick.Its a hybrid

Efficient hybrid vehicles represent a decisive step forward on the

path to electromobility. So what would make more sense than to

pair an economical diesel engine with an electric motor? 2011 saw

one such completely new concept from Bosch going into large-scale

series production: the Axle Split Hybrid System. Here, the diesel

drive to the front axle is supplemented by an electric drive to the rear

axle. The particularly clever feature is that existing vehicle concepts

can be adapted with ease, thus, avoiding the expense of integrating

a completely new powertrain.

Just how emission-free areelectric vehicles?

Driving an electric vehicle produces no CO. But, to ensure a fair com-

parison between the various types of powertrain, it is important to know

how the electricity driving the vehicle is generated because the more fossil

fuel used, the heavier the total carbon footprint becomes. The table on

this page shows the amount of CO released during fuel refinement and

electricity generation (well-to-tank) while driving (tank-to-wheel) and the

overall carbon footprints of the individual types of powertrain (well-to-

wheel) in comparison. So, with todays electricity mix, diesels are, in fact,

on the same carbon-footprint level as electric vehicles.

Be honest now...Do you still believe, as many people do, in those fairy tales of diesels

being smelly, soot-spewing monsters? We can assure you that those

days are long gone. Modern diesel engines of today emit only a tiny

fraction of the particulate they used to. Thanks to intelligent engine-

design measures and highly efficient exhaust-gas treatment, even those

noxious nitrogen oxides have been reduced to a minimum. Since the

introduction of exhaust-gas legislation in Europe in 1990, emissions of

nitrogen oxides and particulate have dropped by an impressive 96 and

98 percent respectively.

When its gone, its goneConserving our natural resources is not just a topic for the future. It is,

rather, a concern of the here and now. Fossil fuels produced over millions

of years can neither be regenerated nor used again. No one can seriously

predict today precisely when the oil age will come to an end, nor can

anyone predict if and when any new natural resources will be discovered

that will allow us to postpone the inevitable. What seems certain from

todays point of view is that there will be a gradual increase in the demand

for fuel in the years and decades to come; however, the available amounts

will fall. Every liter of mineral oil that can be saved today should definitely

be saved.

In Germany, every percentage point by which the relative number of

diesel vehicles can be increased could save around 90 million liters of fuel.

The position in the USA is even more drastic: if every third vehicle were a

modern diesel, the country would be able to cancel its entire crude-oil

imports from Saudi Arabia 1.4 million barrels every day! Taking an

average market price of 80 US dollars in 2010, this would have generated

economic savings of around 40.8 billion dollars, a great deal of money

which could have been invested in the modernization of electricity networks

particularly in the USA Driving a diesel today supports the electromobility

of tomorrow.

Think ahead.Drive farther

A diesel car is generally more expensive to buy than a comparable

gasoline model. All things considered, a diesel is generally more eco-

nomical. No wonder, since a diesel burns about 30 percent less fuel,

which gives an improved range of up to 40 percent. So those who think

ahead not only drive farther, but also drive more economically.

From algae todieselScientists the world over are doing intensive research into sustainable

raw materials for fuel production: raw materials which are neither food-

stuffs nor require precious arable land on which to be grown. Algae may

provide a promising solution here. Diesel fuel processed from this source

can power existing diesel engines without the need for adaptation.

The existing logistics and filling-station infrastructure can also be retained.

Furthermore, there is potential for transforming used cooking oils and

fats into diesel fuel in an environmentally compatible way.

A speedy way to saveIn 2006, most motor-racing fans were surprised when the

Audi team not only entered a diesel into the legendary Le Mans

24-hour race, but actually won it as well! After six more diesel

victories in succession one of which featured a Peugeot

spectators and competitors have meanwhile become used to

seeing the energy of the diesel powertrain virtually sweep the

board. Even the ParisDakar Rally has seen nothing but diesels

in the lead over the past few years.

Daddy, when I grow up,I want to drive an

excavator

Huge, powerful machines such as the diesel engines used for mining,

immense dump trucks and excavators used for highway construction,

to name but a few, continue to fascinate every generation, often in-

spiring our children to dream about their futures. Diesel passenger cars

possess similar power to that enjoyed by their big brothers but on a

smaller scale. Depending on the class of vehicle, a diesel has more torque

than a comparable gasoline model. Take your kids on a test drive.

Afterwards maybe they will also say, Daddy, when I grow up, I onlywant to drive a diesel.

Breaking the iceThere is hardly anything that seamen fear more than pack ice, which

can be a serious threat to supertankers if they fail to stop in time. How

comforting to know that diesel-powered icebreakers can clear paths for

passenger and cargo vessels. And while on the subject of clearing the

way, mining vehicles do a remarkable job clearing out Australias ore

mines. They can remove an incredible 400 tonnes of rock at a time. This

is around 26 times the payload of a normal big truck. And these are but

a couple of examples of the many special fields of application for whichdiesels due to their enormous power and strength are designed.

Admittedly, this statement may seem a bit of an exaggeration to all

those who grow fruit and vegetables in their own gardens, but for

everyone else, its pretty close to reality. All over the world it is mainlydiesel engines which drive the combine harvesters, the root-crop

and potato diggers and the cucumber gatherers (there really are such

things!) that help to bring the harvest home. And there is no need

to remind you that it is diesel commercial vehicles that transport

our food safely and efficiently to local supermarkets.

Fine time for apower cut...

Our electricity networks do not always match up to what we require of

them. And while our reactions to such blackouts in the private sphere

can vary from annoyance to romanticism, critical situations may arisein circumstances where human lives are in acute danger. But before

the lights in operating rooms go out, or the monitors in traffic-control

towers and computer centers cut out, ultra-modern, diesel-powered

emergency generators spring into action within fractions of a second

to avoid catastrophes and where necessary provide the source of

electric power in isolated areas.

Your first diesel

We all know what it feels like to hold our breath, or to get butter-

flies in our stomach or when the hair rises on the back of our neck.

Those very same feelings are experienced by many people whenthey put their foot on the accelerator of a modern diesel vehicle for

the first time. Maximum torque is always there even at low engine

speeds, guaranteeing dynamic and superior forward movement.

And, without breaking any taboos, we can safely say that this is

just good, clean fun. Fun that may be enjoyed with a totally clear

conscience, thanks to the clean and economical diesel engine.Get a

There are still places in the world that are suspicious of diesel.

Fed by the false assumption that the electrically mobile future is

just around the corner, a distorted view of reality has been created.Todays modern, economical, clean and powerful diesels can

actually do much more than many people think. There is a world-

wide network of diesel technology. The relevant infrastructure is

available virtually everywhere. In short, the diesel powertrain brings

us all just that much closer to solving the worldwide challenges

that we face today. Our future with Clean Diesel.
