Euro 4 / Euro 5

New incentives for emissions

Volvo has released an extensive twofold approach to meet the new emissions standards known as ADR 80/02 and will include SCR (Selective Catalytic Reduction) and EGR  (Exhaust Gas Recirculation) solutions.

The new legislation for exhaust reduction imposes tough demands on all vehicle manufacturers. The difference in exhaust emission requirements between ADR 80/01 (Euro 3) and ADR 80/02 (Euro 4) engine is considerable.

Volvo has chosen the more stringent Euro 4 standard as compliance which means that emissions of nitrogen oxides (NOx) are cut from 5 (Euro 3) to 3.5 (Euro 4) g/kWh, a reduction of 30%. Particulate (PM) emissions drop from 0.1 to 0.02 g/kWh. This corresponds to a reduction of no less than 80%.  The other method of compliance is US04 and trucks aligned to this US standard emit 3.35 g/kWh of nitrogen oxides (NOx) and 0.13g/kWh of Particulates (PM). This is illustrated in the diagram below.

SCR also has some significant benefits in that it can already meet Euro 5 standards, which are not mandated in Australia until 2011. SCR technology is not only simple and cost efficient, it provides the platform for future compliance.

Customers considering the new Volvo FL or Volvo FE models are now able to choose their level of compliance and can purchase a truck with a Euro 5 option which is three years more advanced than what is officially required. This option is also available on the Volvo FM and FH models through special order.

EGR has not been ignored and we have maintained our flexibility offering EGR for those customers whose application would be better met by an EGR truck. By offering this alternative, we can meet the needs and special build requirements of our customers.
