Choices of technology<br />
<strong>Scania</strong>’s choices of technology are governed<br />
by concern for the situation of customers.<br />
Exhaust gas recirculation (EGR) is the<br />
solution that <strong>Scania</strong> prefers for reducing<br />
emissions. EGR is easiest for the driver,<br />
who only needs to fill up with standard fuel,<br />
not additives. A combination of unique<br />
<strong>Scania</strong> technologies yields an efficient Euro 4<br />
engine that has the same fuel economy as<br />
a Euro 3 engine.<br />
An EGR system utilises part of a vehicle’s<br />
cooling capacity. <strong>Scania</strong> thus also uses<br />
another technology – selective catalytic reduction<br />
(SCR) – in which a so-called urea<br />
solution known as AdBlue is continuously<br />
added to the exhaust gases in a catalyst<br />
in order to reduce the amount of nitrogen<br />
oxides in the exhaust. This technology is<br />
employed in <strong>Scania</strong>’s most powerful Euro 4<br />
engines to safeguard their cooling capacity.<br />
The vehicle must have an extra tank holding<br />
about 100 litres, as well as a separate<br />
AdBlue injection system.<br />
In its Euro 5 engine, <strong>Scania</strong> will introduce<br />
a new injection system developed in-house<br />
and a more advanced engine platform that<br />
will enable the use of EGR technology in all<br />
engines.<br />
Truck and bus driving pleasure<br />
For many years, <strong>Scania</strong> has been well<br />
known for creating a good driver environment.<br />
This has contributed to its prestigious<br />
brand image.<br />
Many man-years of experience, customer<br />
contacts and development work<br />
are behind the new driver’s workplace in<br />
<strong>Scania</strong>’s new range of trucks.<br />
One of the reasons cited by the jury<br />
that selected the new R-series for the<br />
International Truck of the Year award<br />
was <strong>Scania</strong>’s particular attention to<br />
driver comfort.<br />
The purpose of <strong>Scania</strong>’s ergonomic<br />
refinements is to enable drivers to feel at<br />
home quickly and do the best possible<br />
job. Functions and controls should be<br />
intuitively easy for drivers to understand.<br />
A vehicle should continuously communicate<br />
how effectively it is working. This is<br />
important to enable the driver to take<br />
optimal advantage of its performance.<br />
The driver of a <strong>Scania</strong> vehicle must<br />
always control the situation and be in full<br />
command. This makes it easier to drive<br />
safely, avoid accidents and save fuel,<br />
thereby causing as little environmental<br />
impact as possible.<br />
