DEUTZ Introduces World’s First Hybrid Power Unit for Construction Equipment

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
