3W-International GmbH a new company focused in marketing and selling to the industry: 3W-Modellmotoren GmbH´s 2-stroke Heavy Fuel and gasoline engines.

3W-International GmbH signed exclusive contracts with 3W-Modellmotoren GmbH for:

• Marketing and selling the complete line of Heavy Fuel Engines and Gasoline to the industry world wide
• Production and R & D of HF-Engines and gasoline engines
• Purchase of 3W-Modellmotoren GmbH ´s patents in Germany and USA

Now we proudly present a range of Heavy Fuel Engines (HFE) reed controlled:

• 3W-28xiHFE
• 3W-34xiTS HFE
• 3W-56iB2 HFE
• 3W-68xiB2 TS HFE
• 3W-110xiB2 TS HFE
• 3W-157xiB2TS HFE
• 3W-170xiB2 TS HFE
• 3W-210xiB2 TS HFE

All our Heavy Fuel Engines are available with carburettor or Fuel Injection ( FI ). We successfully converted our 3W-342iB2 TS into Heavy Fuel operation. Very smooth running characteristics. Please note that only 1 prototype is available yet. Our new 3W-370xiB2 TS but piston ported will be shown at the AUVSI in Washington this year in August. We selected a piston ported version to eliminate the reed , a part which can wear. The cylinder bore is the same like our 3W-342iB2 TS , only the stroke is a bit longer.Some more time has to be invested in R&D to find the correct timing for a piston ported engine.

Our know how in piston ported engines is 25 years old and it was used in the beginning of our company start.

The following engines will be converted into Piston Ported Engines in the near future.

1. Engines:

• 3W-34xiTS HFE FI
• 3W-68xiB2 TS HFE FI
• 3W-114xiB2 TS HFE FI
• 3W-370xiB2 TS HFE FI
• 3W-740xiB4 TS HFE FI

2. New Ignition System

Voltage range: 5V – 30 V. Timing curve is programmable. The system is build in an alumimum box with cooling fins.
