DUETZ, a leading independent gas and diesel engine manufacturer, has developed a hybrid power unit for heavy equipment. DUETZ claims the new unit has the potential to reduce fuel consumption by up to 30%. The unit is not only designed to reduce fuel costs and consumption, but CO2 emissions as well.
Here are some of the main specs and functions:
- Mild hybrid drive unit
- DEUTZ four-cylinder diesel engine, electric motor, lithium-ion battery pack, control unit
- Electrical system nominal 15kW output, peak capacity at 30kW
- Start and stop: automatic engine stop during idling phases, automatic engine start in the case of continued operation, the usual starter is omitted.
- Power boost: in the case the power peaks, the electric unit is cut in.
- Battery charging: if the diesel engine has excess power, the electric unit can charge the battery while operating as a generator.
- Recuperation: part of the braking energy is refed into the battery by the electric unit

The new hybrid drive was developed with Heinzmann, a notable manufacturer of engine control systems and long-term DEUTZ partner and supplier. DEUTZ engines are commonly used in excavators, wheel loaders, access platforms, compactors, cranes, crushers, screeners, compressors, lift trucks, tractors, ride-on mowers, chippers, shredders, gensets and other off-highway mobile plant.
