Clean from start to finish: EURO VI exhaust after-treatment box. In view of the high requirements stipulated by the EURO VI emission standard, Mercedes-Benz has developed cooled exhaust gas recirculation (EGR), particulate filters and SCR technology for its new generation of engines. This has already proven to be a winning combination in its use in commercial vehicles from Daimler Buses. Together, the systems results in an extremely efficient exhaust after-treatment. Product features Low exhaust back pressure NOx reduction at a broad range of exhaust gas volume flows and exhaust gas temperatures Small installation space and low weight Significant Long Maximum Consistent possible soot burn-off in the diesel particulate filter (DPF) by means of automatic regeneration service lifetime, adapted to the engine's service lifetime Many addition, adaptive regeneration of the DPF in all relevant driving cycles common parts strategy different variants for exhaust gas inlet and outlet In Large capacity for ash storage in the DPF to make maintenance intervals as long as possible 22 Metering of AdBlue without compressed air; very low AdBlue consumption

Retarder. The integrated secondary water retarder and hydrodynamic oil retarder from Voith offer a high braking torque in combination with a compact, weight-saving design. The weight advantages of the new retarders are between 25 kg (VR 123) and 43 kg (SWR) compared to previous oil retarders. The braking power of the retarder is also independent of selected gear or current engine speed. A gear change does not result in any interruption in the retarder braking action and the retarder braking power depends only on the current driving speed. 36 The braking power can be controlled precisely in five stages using the right hand control stalk on the steering column. In addition to the engine brake, the retarder provides a maximum braking torque up to 3500 Nm (SWR) or 1500 Nm (VR 123).

Secondary water retarder Hydrodynamic retarder VR 123 The secondary water retarder comes with: The hydrodynamic retarder comes with: Power Stainless loss reduction by axial rotor displacement No heat exchanger required since the cooling water is used as the operating medium directly steel heat exchanger Optimized hydrodynamics Integration Compact unit requires only minimal installation space Freedom from maintenance for reduced vehicle service costs into the vehicle management Standard Significantly Increased lighter than comparable hydrodynamic retarder Same comfort through low noise emission Integration Between prop shaft length is determined by the retarder unaffected prop shaft length with or without retarder Power loss reduction by axial rotor displacement into the vehicle management 20 30 % higher constant brake power than current oil retarders 3500 max. braking torque [Nm] 800 max. braking power [kw] 5000 max. rotation [min -1] 1500 max. braking torque [Nm] 350 max. braking power [kw] 3150 max. rotation [min -1] Mercedes-Benz transmission systems Retarder 37
