Abstract
Mercedes-Benz BlueTEC passenger cars have been on the cutting
edge of clean diesel technology since 2006. These BlueTEC vehicles
furthermore passed millions of kilometers in the hands of
customers.
SCR-equipped passenger cars already meet the most stringent
exhaust emissions standards in international markets such as the
USA, Europe and Japan. Diesel engines with BlueTEC technology also
reduce CO₂ emissions and provide the high torque and performance
associated with the diesel engine in addition to keeping exhaust
emissions at the lowest possible level.
Nowadays the requirements for SCR emission concepts are
increasing continuously. In fact the emission legislation is
getting stricter with the LEVIII emission standards in 2015.
Additionally the requirements and effort for on-board diagnosis are
increasing year after year. In combination with ambitious CO₂
targets all these issues constitute the further challenges of
BlueTEC SCR emission concepts for worldwide markets.
The following challenges are the focus of efforts to further
advance the BlueTEC drives: - Reduce development and calibration
effort, - Standardize and reduce the costs of SCR components, -
Improve performance by further reducing exhaust emissions (e.g.,
SULEV) and meeting the special requirements associated with the
ever lower exhaust temperatures of vehicles designed to minimize
CO₂ emissions, - Expand BlueTEC technology by integrating
additional emissions components, and - Combine advanced BlueTEC
emission concepts with CO₂ technology modules such as hybrid
systems.
The SCR-equipped diesel engines from Mercedes-Benz passenger
cars represent ultra-clean drive technology, with low CO₂
emissions, that can be adapted for specific markets and vehicles in
a modular fashion, ideally combined with other CO₂ technologies,
and refined to meet future requirements.
