Engines

Powerful - Small - Light - Low in Vibrations

Our rotary engines are designed for powering generators and can run on almost any fuel, including diesel and hydrogen.

Our two engine series KKM350 with 350ccm respectively 500ccm displacement per rotor offers a wide range of configuration possibilities.

Built for high-performance use in small installation spaces

Running on diesel, our engines can generate/mechanical power from 15 kW to 140 kW, and as prototype KKM504d also up to 180 kWil the running on hydrogen, the power range reaches from 10 kW to 100 kW. Their small and almost cylindrical shape makes our engines ideal for powering generator sets and range extender systems, in stationary and mobile applications, on land and water and in the air.

Customizable to your application

We offer individual configurations of the engines for your applications. The electronic motor control unit (ECU) is manufactured and programmed by us. This enables you to adapt our motors to your system in line with your application.

You need support for the integration into your system? We support you in planning and installation!
