For light heavyweight, the D11 the D13 D16 and future engines V retains its tried and tested system of catalytic emission control, SCR (Selective Catalytic Reduction). Furthermore, V has improved its SCR catalytic coating unit and AdBlue injection system.
To comply with regulations € 6The temperature of the exhaust system must be maintained at a high level more or less constant. V, Therefore, SCR solution combines Exhaust Gas Recirculation (EGR) and uncooled diesel particulate filter (DPF) in their engines € 6 D11 and D13. The technological solution for D5 D8 engines and is a combination of cooled EGR system, particulate filter and SCR.
