Modern exhaust gas after-treatment

Updated


Mercedes-Benz chose the occasion of the New York Auto Show to exhibit the E 250 BlueTec, a prototype specially conceived for the North American market. Essentially, this model is an E 250 CDI with pioneering exhaust gas after-treatment technology. Core components of the BlueTec system are two SCR catalytic converters with an AdBlue injector positioned upstream. The after-treatment process is monitored and controlled by an array of sensors. According to Mercedes, the E 250 BlueTec returns a fuel consumption of 42.7mpg. This clean E-Class is due to arrive in Europe some time during autumn 2009, but with the E 350 BlueTec V6 diesel as its engine.
