Reduced fuel consumption and emissions
New Bosch technologies for commercial vehicles
Hybrid technology for trucks
 Waste heat recovery for even greater efficiency
 Enhanced common-rail and exhaust-gas treatment systems
 Eco-friendly CNG technology for clean commercial vehicles
In addition to enhancing already existing technologies such as common-rail
injection systems and exhaust-gas treatment systems, Bosch is working on
new technologies that improve commercial vehicles’ fuel economy and
reduce their emissions even further. These technologies include hybrid
solutions for the powertrains of medium and heavy trucks and the recovery
of waste heat from the exhaust tract. “Apart from Euro VI, we are focusing
on further reducing commercial vehicles’ CO2 emissions. Moreover, the
additional fuel savings associated with these new technologies will mean
real cost advantages for fleet operators in the future,” said Dr. Markus
Heyn, president of the Diesel Systems division at Robert Bosch GmbH. And
wherever an infrastructure exists for compressed natural gas as an
alternative fuel, Bosch believes that monovalent and bivalent CNG systems
have a promising future. This is also a question of complying with future
emissions legislation in countries such as China or India, which take their
lead from EU legislation. “This is why we offer injection and exhaust-gas
treatment systems which are specially adapted to these growth markets,”
Heyn said.
Extensive hybrid expertise from the passenger-car segment
When designing hybrid solutions for commercial-vehicle powertrains,
Bosch draws on its experience in the passenger-car segment, where
production vehicles already feature Bosch electric motors, power
electronics, and engine management systems. The company is now
transferring this expertise to components and systems for long-haul trucks
weighing up to 40 metric tons and for medium and heavy delivery trucks –

in other words, for trucks that benefit most from electrical powertrains.
Bosch engineers are working on parallel full-hybrid technology that can be
integrated into a commercial vehicle’s drive train without taking up a lot of
space. When driving long distances and on multi-drop delivery runs,
electrical energy can be recuperated when driving downhill or braking, and
temporarily stored in a high-voltage battery. When the truck drives uphill or
starts off, this energy drives an electric motor that supports the internalcombustion engine. “We calculate that this can reduce consumption by
some six percent on long-distance journeys, and by as much as 20 percent
on delivery runs,” Heyn says.
Recovering waste heat from the exhaust tract
A concept for converting the waste heat in the exhaust tract into electrical
or mechanical energy offers a potential fuel saving of roughly five percent.
Today, roughly a part of the primary energy used is lost via the exhaust as
waste heat. Some of this energy can be recovered in a waste heat recovery
(WHR) system, using a steam power cycle. The waste heat in the exhaust
is used to generate steam, which drives an expansion machine. The
mechanical energy gained as a result can be used to drive the crankshaft,
either directly or via a gear unit. Alternatively, the expansion machine can
drive a generator that supplies electrical energy to the on-board vehicle
network or a hybrid powertrain’s traction battery. Bosch is currently
developing various designs for an expansion machine, which is the main
energy-conversion component.
CRSN3: enhanced common-rail system delivering 2,500 bar
In its latest CRSN3-25 version, maximum pressure in the CRSN3 injection
system for medium and heavy trucks has been increased to 2,500 bar.
Thanks to the optimized air-fuel mix, raw emissions are reduced. With a
pressure-balanced interior, the innovative injector concept features an
especially high level of hydraulic efficiency. In conjunction with exhaust-gas
recirculation systems and SCR catalytic converters, Bosch high-pressure
injection systems play a considerable part in reducing consumption and
nitrogen oxide emissions. For example, the Denoxtronic exhaust-gas
treatment system developed by Bosch allows nitrogen oxide emissions to
be reduced by as much as 95 percent. Variant 6.5 of this system has been
adapted to the special requirements of emerging markets. There is also
Departronic, a proven system that injects a controlled amount of fuel into
the exhaust tract to govern the regeneration of the particulate filter. Bosch
common-rail systems, as well as Denoxtronic and Departronic, help
commercial-vehicle manufacturers to comply with the US 10 and Euro VI
emissions targets.

CNG as an alternative fuel for commercial vehicles
Spark-ignition and diesel engines that can also run on compressed natural
gas are gaining in significance in the commercial-vehicle segment. CNG is
especially eco-friendly. CNG engines emit up to 25 percent less CO2 than
conventional diesel engines. Moreover, CNG is less expensive than
conventional fuel. Commercial-vehicle operators thus benefit from the
lower running cost of a CNG engine. Bosch supplies components and
systems for three different approaches to using CNG. First, for monovalent
engines. These are engines that run exclusively on CNG, and which are
mainly found in urban vehicles such as buses or garbage collection
vehicles. Second, for the dual-fuel engines to be found in medium and
heavy trucks, where gas and diesel are burned simultaneously. When using
this system, CNG can be used instead of diesel as much as 90 percent of
the time. Third, for the bivalent engines used in light trucks. Their modified
spark-ignition engines can be run either on CNG or gasoline. Both bivalent
systems and dual-fuel engines offer greater independence in areas where
the gas infrastructure is not so dense, since they can run purely on diesel
or gasoline without any restriction.

PRESS RELEASE
PC_IAA 2012_e
June 2012
World first: ZF Lenksysteme equips light commercial
vehicles with electric power steering

0.6 litres less fuel consumption compared with hydraulic power steering

Reduction in CO2 emissions

System capability enables the steering to be networked with driver assistance systems
After the passenger car market, the ZF Lenksysteme Servolectric, which is designed for optimum fuel consumption, is now also conquering the high-volume light commercial vehicle (LCV) business sector. More than
23 million Servolectric power steering systems have already been produced. Of these, around 2.6 million are
made in the paraxial design with the highest steering rack
force. With minor modifications, this electric power steering system can be adapted for light commercial vehicles.
Compared with hydraulic steering systems, the ZF
Lenksysteme Servolectric saves around 0.6 litres of fuel in
the NEDC (New European Driving Cycle) in urban traffic. A
further advantage is the system capability, i.e. networking
with electronic assistance systems. This means increased
safety and convenience for the customer.

Less fuel consumption - less carbon dioxide
The ZF Lenksysteme Servolectric only needs power when
the steering is activated. According to the latest measurements, the electric power steering system saves
0.6 litres of fuel in 100 km compared with hydraulic power steering systems. With an annual mileage of 25,000 km
per year, this means a saving of 150 litres of fuel due to
the steering alone. With a litre of diesel costing
1.40 euros, this amounts to 210 euros per year.
There are also considerable potential savings with regard
to CO2 emissions. The Servolectric produces 16.1 g/km
less CO2 compared with hydraulic power steering. With
an annual mileage of 25,000 km, this results in a saving of
around 0.4 tonnes of CO2. The legislator has also decided
to introduce an EU-wide CO2 penalty tax for commercial
vehicles which emit more than 147 g/km CO2. This will
come into force in 2014 with a limit of 175 g/km. A staggered introduction will ensure that the limit of 147 g/km
is reached step-by-step by 2020. Here too, the Servolectric shows enormous savings potential.
Power-on-demand
The Servolectric is based on the principle of rack-andpinion steering which, in the case of electric steering, is
linked to a servo unit and a highly developed electronics
system. As soon as the driver initiates a steering movement, sensors register the appropriate steering torque
and steering speed. From this data, a control unit calcu-
2 of 4
PI7786
lates the necessary steering assistance within milliseconds and the servo motor transmits the optimum
torque via a recirculating ball gear to the rack of the mechanical rack-and-pinion steering. The power limit of this
steering system corresponds to a steering axle load of
more than 2,000 kg. However, the electric steering system in paraxial design introduced in 2006 offers even
more advantages: the space-saving installation due to the
absence of steering pump and hoses simplifies assembly
and relieves the burden on the environment. Along with
passenger car steering systems, the ZF-Servolectric now
also covers light commercial vehicles (LCV) such as the
Mercedes Sprinter and the Volkswagen Crafter. This versatile steering system can therefore be found in vehicles
ranging from the mini class via the medium and luxury
class to the transporter.
System capability allows for safe driving
The Servolectric can be networked with a number of external systems. Information gathered relating to the
steering wheel angle is thus available to other systems
such as ESP or an adaptive chassis controller. It also facilitates driving safety functions such as lane departure
warning and lane change assistant. Depending on the
driving situation, the appropriate system intervenes and
recommends a steering correction to the driver by visual,
acoustic or haptic signals. It is no longer necessary to
hold the steering wheel when using the parking assistant
feature. In this case, the Servolectric completely takes
over the steering by itself.
