Volvo Trucks - I-Torque, a top-performing driveline for energy efficient transport (new Volvo FH)

Uploaded by VolvoTrucks on 05.09.2012

In conjunction with the launch of the new FH series,
Volvo Trucks also introduces a completely new driveline: the I-Torque.
Hitting the market in autumn 2013, the I-Torque has the potential
to offer up to 10 percent fuel savings and generate exceptional drivability.
However, Volvo Trucks' standard Euro 6 engine
will be available as early as this spring.
Our new Euro 6 engine is a direct continuation of our Euro 5 engine.
It has the same drivability, same engine curves,
but it has, of course, a much more sophisticated after-treatment system.
The Euro 6 engine's enhanced after-treatment system
reduces particulate emissions by 50% and nitrogen oxide emissions by 77%.
by almost 80 percent compared to Euro 5.
This engine is, you can say, a multipurpose engine.
It's good for both city application, for construction,
and also in long and regional haul.
Volvo Trucks' next big step towards sustainable transport solutions
will be taken when the next generation of drivelines,
the I-Torque, hits the market. Unlike the standard Euro 6 engine,
it's primarily optimised for long-haul transportation,
and has the potential to save a lot of fuel.
How much you save with the I-Torque is, of course, dependent on how you drive.
We see very good saving compared to Euro 5 - up to 4 percent.
Combined with the minor hardware updates of the new FH series
and the innovative driving system I-See,
fuel consumption can be cut by as much as 10 percent.
Just like the Euro 5, the I-Torque engine is available at 460 hp.
The big difference is that the I-Torque manages to generate
a much higher torque than the Euro 5:
2800 Nm compared to the previous 2300 Nm.
The I-Torque engine is also optimised for much lower and narrower revs,
between 900 and 1200 rpm.
Within that optimised drivable span of 300 rpm,
there are fewer combustions and less friction,
which makes the engine more fuel-efficient.
However, driving within such a narrow band also means there is no margin
for the loss of power, which puts a high demand on the transmission.
Normally it shouldn't be possible to drive in such a narrow band.
But with the new I-Shift 2, that actually works with a powershift,
it gives the perfect support to the driver.
The I-Shift 2 is basically two shifts in one.
Or, more correctly, two input shafts, where each input shaft
is alternately connected to the engine through two clutches.
This makes it possible to change gear instantaneously,
without any interruption in power delivery.
When the first gear is engaged by one gearbox,
the next gear is already engaged in the other one,
and you have a seamless step from one gear to the next.
The I-Torque gives the driver the perfect drivability.
You have a quick response, you have quick and smooth acceleration.
The driver can really focus on traffic and traffic safety.
And the fuel consumption...
That is solved by the technology in the engine and transmission.
