Volvo is ready for Euro 6

Our solution for Euro 6

What is Euro 6?
Compared with the previous standard, Euro 6 mainly targets two types of emissions: oxides of nitrogen (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 even the smallest particulates.

Euro 6 becomes mandatory for all new heavy trucks from 1 January, 2014.

Engine
A closed loop butterfly, a waste-gate turbo, a so-called uncooled EGR and more. The new engine components serve two main purposes: to improve gas-flow and make sure the exhausts reach the after-treatment system at optimum temperature.

7th injector
A special diesel injector is used for heat management of the DOC and ensures the efficiency of the DPF and good SCR functionality.

Diesel Oxidation Catalyst (DOC)
The DOC produces the NO2 necessary for the DPF to efficiently combust the particulates. In cold conditions, it also provides the heat needed for regeneration.

Diesel Particulate Filter (DPF)
The filter collects particulate matter (PM) and stores it until it’s burned off during regeneration. The regeneration is done automatically and the driver doesn’t need to take any action.

Selective Catalytic Reduction (SCR)
In the mixing zone, the exhausts are sprayed with AdBlue. When they reach the catalyst, the nitrogen oxides (NOₓ) are efficiently transformed into harmless nitrogen gas and water.

Ammonia Slip Catalyst (ASC)
The last step before the tailpipe where the remaining ammonia (NH3), if any, is removed.
