Our engine product portfolio: TCO reduction at its best. Bringing together the very latest innovative engine technology, they are designed with focus on environement, effectiveness and performance.

Based on these characteristics our engines in all series are ideal for city buses and touring coaches. They can also be modified to create customer-specific variants for use in different bus applications.

The benefits for our customers are low fuel consumption, long engine life and extended maintenance intervals. Our new engines deliver a spontaneous response, impressive power output and the smoothest running characteristics.

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

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).

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

•
