Rotary Engines & Solutions by Wankel Supertec

Rotary Engines of Wankel Supertec feature several unique advantages:

Due to the modular design, our motors can cover a wide power range up to 200 kW. Besides, this constructive feature ensures high standardization level of WST rotary engines, which results in low production and maintenance costs.

Another distinctive characteristic of WST engines refers to their multifuel capability. A number of unique engineering solutions in optimization of combustion chamber, fuel injection and engine control unit enable our rotary motors to run on Diesel, Jet Fuel, Gasoline and Hydrogen without any significant alteration of the basic motor.

Modern production methods along with application of new materials helped our engineers solve the sealing problem common to all Wankel engines. The optimization of material pairings between sealing parts and sliding surfaces significantly improved the durability and reliability of WST rotary engines.

KKM350: Lightweight, compact and multi-fuel!

Based on a concept of a ultra-light, compact engine unit for Diesel and aviation fuels, we designed the KKM350. Our smallest rotary engine weights only 28 kg, which can only be compared to a two-stroke engine.

  • Size from one up to three rotors
  • Power range: 5 to 90kW
  • High power-to-weight ratio
  • Simple maintenance
  • Low cost production because of modular design
  • Small rotary engine
  • Runs with Diesel, Kerosine, Petrol and gases

KKM500: Powerfull - and still lightweight!

Our KKM500 also has the possibility of burning a variety of fuels, liquid and gaseous. With a net power to weight ratio of 1kW/kg for a single-rotor up to 1,7kW/kg for a four-rotor rotary engine.

  • Size from One up to four rotors
  • Power range: 22 to 200kW
  • High power-to-weight ratio
  • Simple maintenance
  • Low cost production because of modular design
  • Very compact engine design
  • Runs with Diesel, Kerosine, Petrol and gases

Hydrogen Rotary Engine: for sustainable power & mobility

On 20 September 2019 our team accomplished the first successful test of WST rotary engine driven by Hydrogen. The technology combines advantages of rotary engines with the vast potential of Hydrogen as a clean and abundant fuel of the future.

  • Emission-free
  • Can be driven by inexpensive low-purity Hydrogen
  • Ease of repair & eco-friendly recycling
  • Low vibration levels
  • High durability
  • Modular design covering a wide power range

Engine Control Unit

In cooperation with its partners, Wankel Supertec developed a unique engine control module to ensure optimal engine performance. This compact electronic control unit enables precise regulation of the rotary engine through the integration of all required subsystems. It does this by reading values from multiple sensors within the motor bay, interpreting the data, and adjusting the engine actuators.

The possibility of two-directional data exchange between the engine and an entire system guarantees precise and flexible adjustment of the Wankel motor to a specific application.

  • Adapted to a specific application
  • Enables two-directional data exchange
  • Enables precise control of a rotary engine
  • Compact

Fuel Pump for Rotary Engines

The capability to run on multiple fuels represents one of the major competitive advantages of WST Wankel rotary engines.

To make it possible, our team had to overcome a few significant challenges. One of them referred to development of a unique high pressure pump which could effectively work with multiple liquid fuels.

Our engineers managed to solve this complex technical issue by developing a compact and light-weighted fuel-pump lubricated with engine oil.

  • Max feed pressure up to 1600 bar
  • Lubricated with engine oil
  • Compact: installation on crankshaft
  • Light-weighted: only 200g! Far lighter than regular 4kg fuel pumps
