Iveco’s concern
for the environment is one of its core values, with this
issue being of major importance to both customers and
society in general. Thanks to continued research and
development, Iveco engineers have developed eco-friendly
vehicles which are designed to reduce fuel consumption,
greenhouse gases, exhaust emissions and noise. They have
also worked hard to ensure that vehicles can be easily
recycled at the end of their life, thus saving both
materials and power resources.
Iveco’s approach to using state-of-the-art technology to
reduce emissions is far-reaching, taking into consideration
the evolution of standards on emission limits, technology
and – last but not the least – optimising purchase and
operational costs. In this way, Iveco is able to offer the
most reliable, developed and specialised solutions for any
mission. The purpose of Iveco’s extensive research goes
beyond simply observing environmental standards; thanks to
the analysis of the customer’s needs, it is aimed at
ensuring the vehicle’s performance and economy. Iveco’s
entire range of products is built around this philosophy,
optimising solutions according to the specific mission of
different vehicles in the various sectors: light, medium and
heavy, as well as those for personal transportation and for
special operations.
Euro 4/5 Technologies
At present the interventions on combustion alone
are not able to reduce at the same time the level of
particulate (PM) and nitric oxide (NOx) emissions, which are
the most critical pollutants for diesel engines. Any
intervention on the engine alone reduces the emissions of
one pollutant but increases those of the other. As a
consequence there are two options: to abate particulate
emissions by acting on combustion and to decrease the nitric
oxide through the post-treatment of exhaust gases (SCR
technology); or to reduce the nitric oxides to minimum
levels by acting on combustion (EGR technology), thanks to
exhaust gas recirculation.
The greatest advantage of the SCR technology is that it
allows a significant decrease in fuel consumption (up to 5%)
with respect to Euro 3 engines. In addition, this technology
is already able to meet the Euro 5 emission standards, which
is coming into force in 2009. The SCR technology uses only
one chemical reactant named AdBlue (water solution of urea),
which reacts with the nitric oxides once it has been sprayed
into the exhaust gases and transforms them into harmless
substances. The consumption of AdBlue can vary between
vehicle types, but is usually within 3% and 5% of fuel
consumption. The SCR makes the PM filter redundant, since
the production of particulate is minimal. Iveco has studied
and developed both EGR and SCR technologies and believes
that the adoption of SCR technology for medium and heavy
vehicles and EGR technology for light vehicles is the best
overall solution.
Iveco and the SCR system
The Iveco-SCR technology enables an ideal
compromise to be reached between two important needs of the
customer: on one hand it allows a reduction in fuel
consumption and in the cost of manufacturing engines, at the
same time, improving the performance and extending the life
of the motor-propulsion units; on the other hand it allows
full compliance with rigorous Euro 5 emission standards
established to safeguard the environment.

All Eurocargo,
Stralis and Trakker models will use SCR, which represents
the appropriate technology for vehicles where goods
transport is the core activity, since fuel consumption is of
major importance due to the likely high vehicle mileage
requirements. In addition the very low level of particulate
produced through combustion reduces the contamination of the
lubricating fluid oil and allows extended maintenance
intervals, which further enhances the vehicle’s
productivity. Thanks to its compliance with the Euro 5
standard, the SCR system also allows operators in certain
countries (such as Germany) to benefit from reduced motorway
tolls which have been introduced for early adopters. It is
also expected to result in higher residual values for used
vehicles.
With regard to the availability of AdBlue, Iveco dealers
across Europe are offering AdBlue for sale from their part’s
departments, ensuring customers have easy access to AdBlue
supplies when placing routine parts orders. AdBlue can also
be purchased from a growing number of large filling stations
and truckstops.
Iveco and the EGR system: the best choice for light
means
For vehicles across the new Daily range, EGR has
been selected as the favoured technology in terms of
balancing fuel consumption, weight and cost. This
technology is also universally accepted today on cars and
light vans, and there is no requirement for the use of
Adblue. Models up to and including the
Daily 50C will use EGR plus an oxidising catalyst and
certification will be according to the light duty van
procedure (70/220/EC). Models above the Daily 50C will use
EGR plus a diesel particulate filter (DPF) and certification
will be to the heavy duty procedure (88/77/EC). In order to
comply with the particularly restrictive rules adopted in
some towns, lighter Daily vehicles may also be equipped
also with a diesel particulate filter (DPF). This system
allows the full environmental compatibility even on
congested inner-city roads or for rigorous stop-start
distribution runs.
Iveco EEV: the winning solutions for urban transport
Iveco’s commitment to low emission vehicles does
not neglect the special requirements of local public
transport, where the safeguard of air quality is
fundamental. For years Iveco has been leader in the
production of natural-gas powered urban buses compliant with
EEV standards (Enhanced Environmental Vehicles), which are
at present the most strict among the European Union
standards.
Thanks to the experience practiced with the SCR technology
and through the evolution of particulate filters, Iveco is
able to meet these standards also with Diesel powered
vehicles. For example, Iveco urban busses are equipped with
an SCRT system (a combination of SCR and particulate trap)
and are EEV certified. It is another example of the
continuous effort to develop advanced solutions for the
specific needs of our customers.
