Mercedes-Benz BlueTec EEV trucks

  • In certain output classes of the Actros and Axor, the BlueTec EEV version will be gradually introduced from autumn 2009 to July 2010
  • Atego > 12 t available in all output classes from March 2010
  • For the Econic, BlueTec EEV is part of the extended specification from January 2010
  • Particulates reduced by one third versus Euro 5
  • Country-specific subsidies for EEV technology

EEV (Enhanced Environmentally Friendly Vehicle) is a classification used for engines which comply with an even more stringent exhaust emission standard than Euro 5. The EEV standard reduces particulate emissions by roughly a further one third compared to the already stringent Euro 5 limits. In extending its truck range, Mercedes-Benz will be gradually introducing EEV versions in certain output classes of the Mercedes-Benz Actros, Axor and Atego up to July 2010. BlueTec EEV is already part of the extended specification for the Mercedes-Benz Econic from January 2010.

Incentives are offered for this technology in some European countries. The engines in the OM 920 and OM 501 series have been developed even further for this purpose. Mercedes-Benz commercial vehicles equipped with this feature can be recognised by the additional “BlueTec EEV” model plate.

Since October 2009, the optional, ex factory availability of BlueTec EEV vehicles has applied to on-road Mercedes-Benz Actros trucks in the output classes 300 kW (408 hp), 320 kW (435 hp) and 335 kW (456 hp), as well as the Mercedes-Benz Axor in output classes 210 kW (286 hp) and 240 kW (326 hp). From July 2010 the Actros will be available in a BlueTec EEV version for the variants with 235 kW (320 hp) and 265 kW (360 hp), thereby extending the BlueTec EEV range in the OM 501 LA engine series (the largest engine developing 350 kW is not available in an EEV version).

From March 2010 the entire Mercedes-Benz Atego series with all output classes of the OM 924 LA engines (130 kW (177 hp), 160 kW (218 hp)) and OM 926 LA engines (175 kW (238 hp), 188 kW (256 hp), 210 kW (286 hp)) will be available in EEV versions.

As a significant product enhancement and to improve value retention even further, BlueTec EEV is included in the extended standard equipment of the Mercedes-Benz Econic, which is frequently in service as a municipal or distribution vehicle in environmentally sensitive inner-city areas. This applies to both the 210 kW (286 hp) and the 240 kW (326 hp) diesel engine variants.

The technology for compliance with the voluntary EEV emission standard is based on the new BlueTec 5 diesel ­technology from Mercedes-Benz, which involves the installation of additional technological features. In the EEV version of the OM 501 LA engine, a change to the engine’s characteristic map has led to a reduction in particulate emissions by more than 30 percent.

To this end the injection nozzle pressure was increased, and the injection nozzle/line/attachment system was redesigned. Substantial technical modifications were made to the OM 920 LA engine series, of which EEV versions can be ordered in all available output classes as the OM 924 LA EEV and OM 926 LA EEV. Additional exhaust gas aftertreatment is not necessary. In terms of maintenance, operating life, fuel consumption, weight and installation space, the EEV solution adopted for Mercedes-Benz trucks is at the same level as with the well-proven BlueTec 5 technology.

Subsidies for EEV technology: in Germany, EEV is subsidised for trucks over 12 t permissible gross vehicle weight under a government-approved support programme operated by the KfW Bank (redefined figures will apply from spring 2010 in Germany) In the Netherlands there is also a subsidy available under a government support programme. A subsidy in the form of a ten percent reduction in motorway toll charges is also granted for EEV vehicles in Austria. Customers whose Actros is already equipped with an NOx sensor (from autumn 2007) are able to retrofit the EEV technology, thereby also benefitting from the reduced toll charges.
