Continental recently announced the CD-300 diesel engine. Turbocharged, Jet-A burning, 310 horsepower, 562 lbs (just 25 lbs more than the TSIO-550-K). It was also recently retrofitted by Continental into an SR-22 and test flown in Germany, and Continental was pleased with the results. My question for you Cirrus experts is whether this would work for Cirrus to adopt as their new engine for the SR-22T someday. Obviously this will take a while: Plans call to have the engine ready for review by airframes in 2015 and certification following a year later. Continental will first seek European Aviation Safety Agency certification, followed by U.S. FAA and Chinese CAAC validation.
But is there any technical reason why this engine wouldn’t work for the SR-22T?
