Key Takeaways:

  • MWFly, an Italian company, has introduced a variable compression ratio engine design to manage torsional loads on small geared engines.
  • The innovative system reduces compression at idle and low speeds, then increases it when more power is required.
  • This design aims to reduce weight and parts count without compromising performance, offering an alternative to traditional clutches or dog gears.

An Italian company named MWFly has come up with an intriguing way to handle the problem of torsional loads on small geared engines. Rather than a clutch or a dog gear to absorb the loads, MW’s idea is to reduce the loads in the first place so it has developed a variable compression ratio design that backs off compression at idle and low speeds, but allows it to return to high compression when more power is needed.

In its first showing in the U.S. market at Sun ‘n Fun this week, MWFly showed AVweb how this clever idea works. In this exclusive AVweb video, the company’s Guido Fantini said the variable compression ratio approach reduces weight and parts count without a loss in performance.
