Mystery Cessna plane not so mysterious

July 22, 2012 by Alton K. Marsh, Senior Editor, AOPA Pilot


A Cessna 182 is sitting in the Cessna Aircraft exhibit space at Oshkosh, waiting for the Monday opening of EAA AirVenture 2012 and it is not all that mysterious. First of all, it says “Turbo” in bold black letters on the aircraft. So it is a turbo something. After that, experts in the installation of diesel engines say it is obviously an SMA¬† diesel engine that will now be offered in Cessna 182s. However, we won’t know for sure until the masking tape and paper masks come off Monday. So act surprised, OK?

    Will this power plant be available to the retro-fit market to repalace exiting power plants?
    This appears to be a more efficent and better power to fuel ratio than any other equipment I am aware of. How does the weight of this unit compare with say an O-360 or other conventional power plants.

    Hi, RIchard,
    Sorry to take so long to get back to you. The SMA site says the engine is available to private owners. See that comment here: http://www.smaengines.com/spip.php?rubrique2&lang=en

    This brochure says the SMA engine weight is 455 pounds ( http://www.smaengines.com/IMG/pdf/fiche_SMA_ang.pdf).

    This brochure says the Lycoming O-360 engines (there are 17 to choose from, some not fuel injected, some injected, some both injected and turbocharged, etc) are 285 to 400 pounds. The O-360s range from 285 to 301. So your answer is, “heavier.” ( http://www.lycoming.com/engines/series/pdfs/360ci%20Engine%20Insert.pdf)
