Volvo Trucks will produce engines-
-tailored for the tough Euro 6 environmental standards.
First off the mark is Volvo's D13 460 hp engine-
-which today powers more than one third of all Volvo trucks.
Compared with today's Euro 5 standards-
-nitrogen oxide emissions dropped by nearly 80 %-
-and particulate emission are halved.
The Euro 6 engine will hit the market during the spring of 2013.
Euro 6 is important as we want to contribute, become a better player-
-and support the environmental aspect of what we are doing.
Let's have a closer look at the new engine.
First the exhaust gas reaches the DPF, the Diesel Particulate Filter-
-where particulates are captured and burned.
The flow continues to the AdBlue mixing box-
-where AdBlue is injected into the exhaust stream.
The exhaust and AdBlue mix goes through two parallel SCR catalysts-
-where the nitrogen oxides are converted into pure nitrogen-
-and water vapour.
At the end a Slip Cat takes care of any remaining ammonia.
The cleaned exhaust gas comes out of the tail pipe.
Let's take a closer look at some of the details.
To treat NOx, especially in cold driving conditions like in a city-
-the EGR, Exhaust Gas Recirculation, is activated.
It mixes with the cold charge air to get less NOx in the combustion-
-and to get a higher exhaust temperature-
-which is needed for good SCR functionality.
Another way to increase exhaust gas temperature-
-is to create back pressure by means of the exhaust engine brake.
Under normal and tough driving conditions-
-the DPF filter is self-regenerating.
In cool cycles the catalysts and filter need some extra heat.
Diesel in sprayed into the exhaust by the 7th Injector.
When the diesel hits the oxidisation catalyst-
-it burns and creates heat for the filter regeneration.
In the near future, Volvo will expand its range of Euro 6 engines.
We will start with the most frequent 13 litre engine-
-which is the 460 horsepower engine.
We will of course have a full range of Euro 6 engines-
-before we get into legal demand for Euro 6 on the 1st January 2014.
