A BREAK THROUGH IN HEAVY – FUEL TECHNOLOGY!!

3W –MODELLMOTOREN GMBH

Proudly announces the development of a family of 4 Heavy –Fuel –Engines:

3W – 28i HFE / 3W- 56iB2 HFE
3W – 110i B2 TS HFE / 3W – 157 XI B2 TS HFE

Some highlights:

  • Standard cylinders and pistons are used .The same we use for our gas engines.
  • Standard 3W-ignition (s) with standard spark plug (s).
  • Modified standard diaphragm carburettor.
  • Special air intake system.
  • Cold start system using cartridge heaters only for the cold start.
  • Special mufflers or headers.
  • Fuel used for testing: JET A-1 with 5% oil.
  • No power loss compared to gasoline engines.
  • HFE engines run 30 - 40°C cooler than gas engines.
  • Running characteristics are soft due to the lower compression compared to gas engines.
  • The modified carburettor operates like a mechanical fuel injection system in combination with our air intake system.
  • More details have to be discussed personally.

Some test results:

3W – 28i HFE:
Stable idle: 1500 RPM
Max. RPM 10.000, no drop in RPM was noticed during a 10 min test run

3W-56i B2 HFE:
2 x 3 hrs test run with 6600 RPM, no drop in RPM was noticed
Other 3W-engines can be converted to HFE upon request or custom made engines can be designed.
