Setra Busses Meet EEV Standards without Particulate Filters

Daimler announced that its Neu-Ulm Setra touring coaches and rural buses will optionally be available for delivery starting from October 2010 in compliance with the EEV emissions standard without a particulate filter.

The option will be offered on vehicles powered by the six cylinder in-line MO 457 LA engine in both vertical and horizontal design. This covers the S 415 HD touring coaches and all DHD models belonging to the TopClass 400, all models of the ComfortClass 400 of up to 14 m in length and all UL and NF models of MultiClass 400.

The EEV (Enhanced Environmentally Friendly Vehicle) emissions standard is the most strict European emissions regulation, allowing levels that are inferior to those permitted by the Euro 5 standard. For example, the ETC (European Transient Cycle) has a particle emissions standard that is 30 percent lower than the one set by the Euro 5.

Daimler’s BlueTec engines achieve this levels by internal engine measures and modifications to the injection system, without requiring an additional particulate filter. The EEV solution matches the BlueTec 5 technology in terms of fuel consumption, maintenance, service life and weight.

Vehicles that comply with the EEV standard benefit for lower toll rates in transit countries, such as Austria.

For customers who need maximum separation efficiency (one example would be public transport operations), Daimler offers the EEV in combination with the SCR technology (Selective Catalytic Reduction), which includes an additional diesel particulate filter. The combination is available for the Setra NF and UL models of the MultiClass 400 line.
