BlueTec® is the forward-looking SCR diesel technology from Mercedes-Benz: a convincing solution, in economic and ecological terms, enabling your Vario to meet the Euro 4 emission standard

The SCR (Selective Catalytic Reduction) exhaust gas aftertreatment technique is the only technology that permits the necessary reduction in emissions while optimising engine performance and fuel consumption.

The BlueTec® system comprises state-of-the-art engines with enhanced peak pressures to improve combustion and reduce particulates. Other system components are a catalytic converter and an AdBlue tank. The AdBlue additive is simply obtained from a pump at a filling station and carried in a separate tank. A metering unit feeds it into the exhaust gas, whereupon the heat turns it into the ammonia needed for the chemical reduction in the catalytic converter. There the nitrogen oxides are converted by catalytic chemical reaction into ecologically harmless nitrogen and water.
