Volvo is ready for Euro 6

Volvo is ready for Euro 6. Here’s D13K460.

Euro 6 is here. It’s the most stringent European emission standard to date. D13K460 is our first engine to fulfil the demands. Here are all the facts. 

What is Euro 6?
Compared with the previous standard, Euro 6 mainly targets two types of emissions: nitrogen oxides (NOX) and particulate matter (PM).

The limits are extremely strict:

  • NOX is reduced by 80% – to 0.40 g/kWh (steady-state cycle)
  • NOX is reduced by 77% – to 0,46 g/kWh (transient cycle)
  • PM is reduced by 50% – to 0.01 g/kWh

The latter is actually even tougher, since not only the weight, but also the number of particulates count. To fulfil this demand, a Diesel Particulate Filter (DPF) is needed, to capture also the smallest particulates. 

Euro 6 becomes mandatory for all new heavy trucks from 1 January, 2014. But it may be a good option to invest in the new technology sooner than this.

Our solution for Euro 6
Selective Catalytic Reduction (SCR) was our choice for Euro 4 and Euro 5. We’ve now refined this technology further to comply with Euro 6 without compromising engine performance.

To keep the NOX levels down, we’ve added an un-cooled EGR (Exhaust Gas Recirculation) system to the engine. It makes sure the driveability is maintained, while optimising exhaust-gas temperature and NOX levels for efficient after-treatment.

In addition to the SCR catalyst, the after-treatment system has been equipped with a DOC (Diesel Oxidation Catalyst), a Diesel Particulate Filter (DPF) and an Ammonia Slip Catalyst (ASC) – all contained within the same muffler.

D13K460 – many news but few differences
Except for it being considerably cleaner, you won’t notice many differences between D13K460 and its Euro 5 sibling.

Power and torque curves are exactly the same, providing the same excellent driveability. And the fuel consumption is almost on par with the efficient Euro 5 engine.

Furthermore, the particulate filter regenerates itself under normal driving conditions, and is changed at regular service intervals.
