A breakthrough 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

All 4 prototypes can be demonstrated at any time to customers being seriously interested in cooperating with us. We are interested in selling the complete family of HFE engines including our development costs and an exclusive sales right world wide for these 4 engines. The production of all HFE engines will stay in Germany. Another solution can be discussed. The final design of 2 engines (3W-28i and 3W-157XIB2) is ready to be discussed.

A patent is pending in the USA and Germany. From both offices we received their patent application numbers already. 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. R

unning 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.
