28 VDC / 17 kW APU
New concept: „engine with Perkins Typ 404D-15“
Basis: 4 cylinder Perkins 404D15
- Four cylinder Industrial engine from family 400
- Power 26,5 kW @ 3000 rpm
- Mechanical indirect injection system, suitable
for Diesel and Kerosene
Adaptation of the engine including:
- dry sump lubrication, which increases the
tilting angle nearly to horizontal
- modification of exhaust system
- modification of valve cover, oil pane
- interface to generator
- max. speed increased from 3000 to 3600 rpm
- different changes for APU requirements

Engine-Generator Set system system
The APU has been developed as a compact, fully integrated unit, as a result of which it
can be installed in vehicles with a relatively small amount of available space. The
sophisticated modular design enables the APU to be fitted in the vehicle in split
configurations where, for example, the generator set is mounted in one location while
the associated peripheral units are mounted next to it.
