Engine 3W-342i-B2F

Our national and international success is based on our 25 years Know How in designing and producing high quality 2 – stroke engines. The 39 years of industrial experience of our designer had been realized in our new range of engines representing the latest state of the art of 2-stroke technology. Having this in mind a new generation of mufflers had to be developed suitable to handle the higher degree of saturation and process of combustion efficiency. 3W developed these new types of mufflers. Now 3W- Modellmotoren GmbH is capable to deliver complete solutions of propulsion Systems. 3W-Engineering System Use our Kow How and ask us for a quotation for your customs build engine. Design is done by 3D-modeling using CAD Pro Engineer, prototype engines by using Lost Wax moulding and / or Rapid Prototyping , test runs and mass production in our facilities. 3W – History 1985 Introduction of the first 2-stroke gasoline engine especially designed for airplane models : 3W-60 1986 Development and production of 3W-40 and 3W-80B2 opposed twin 1987 Development and production of 3W-35 as well as the first 2-cylinder in-line-engine : 3W-80R2 1988 Development and production of : 3W-120B2 1989 Development and production of 3W-70B2 as well as the first 4-cylinder 3W-240B4 and 3W-160B4 1991 Development and production of : 3W-48B2 1992 Development and production of 2-cylinder in-line engine 3W-120R2 as well as 3-cylinder in-line engine 3W-120R3. Quique Somenzini demonstrates the first torque-roll using 3W-70B2 at the TOC in Las Vegas. 1993 Development and production of 4-cylinder opposed 3W-140B4 and 3W-156B4 1994 Steve Stricker is the first pilot at the TOC , using a 4-cylinder opposed in his Extra with 3400 mm wing span : 3W-160B4. Quique Somenzini won this TOC with 3W-120B2 1994 / 1996 Most popular and spectacular manoeuvre at the TOC : Torque Roll. Most used engine 3W-120B2 1995 Start of the new i-serie representing a new cylinder and piston technology. First engines : 3W-70i and 3W-
