Auxiliary Power Unit
KKM 351d BHS
The system consists of our diesel-powered Wankel engine KKM351d, an air-cooled generator, exhaust gas aftertreatment and self-developed electronic control unit (ECU), including all auxiliary units.
It mainly functions as a power generator for charging the batteries, as well as the on-board power supply when the locomotive is at standby.
The thermal energy generated is used to bring the locomotive's main diesel engine to an appropriate thermal level or to keep it stable.
This reduces consumption, noise and exhaust emissions when the locomotive is at a standstill and improves starting performance by preheating the main engine.
For military applications
The compact design of our engines allows us to build generator sets that are unique not only in size and weight.
The low-vibration and quiet running of our rotary engines gives us the advantage of saving on vibration dampers and sound insulation. With our systems, we achieve weight savings of 25% to 50% compared to similar units.
Our engines run on a variety of liquid and gaseous fuels such as diesel, kerosene, gasoline, hydrogen and biogas. This means they can be operated in crisis areas where neither a stable supply of a particular fuel nor the quality of the fuel can be guaranteed.
H2 Generator Set
Sustainable power generation & mobility
Key advantages of the range extender system
- Longer range
- Shorter charging stops
- Reduction of harmful emissions
- Reduced consumption of rare materials that pollute the environment
Additional advantages of hydrogen engines compared to fuel cells
- Lower weight
- Less expensive
- No use of rare materials
- Does not require high purity hydrogen
