While at the AERO Airshow we
had the pleasure to talk to Arnim Wegener and Jennifer
Hasslinger. Arnim introduced us to the FlyEco Turbo charged
Smart Diesel engine for ultralight and light sport aircraft. This engine
gets its heritage from the Mercedes Smart Car, which Arnim
has been working on for over seven years.
Arnim said that is very similar to the Smart Car
engine, with modification to compensate for the vibration
and loads associated with aircraft application. Arnim felt that ultralight and
light sport aircraft needed an more fuel efficient engine,
without sacrificing horsepower. The Smart
diesel is an 80HP engine.
In testing Arnim used two identical aircraft one powered by
the FlyEco Turbo charged engine the other the 912 ULS 100 HP
Rotax engine. The FlyEco Turbo averaged on 2 gallons of fuel
per hour, considerably less the the 912. The FlyEco Turbo
installed weight is also 10 lbs lighter than the Rotax.
A TBO of 1800 hours was completed in the testing phase.
Arnim said that "when we took test engine apart we saw there
was little to no wear". So they are confident that in 1-2
years the TBO which is currently 1500 hours will be
increased to 2000 hours.
