Hi Rabauss,
I have been flying the Thielert Diesel engine in a 172 now for five years or so...(first the 1.7 and now the 2. litre engine). If you want to set out any questions about handling please do and I will try to help...or else PM me for the information.
Please bear in mind...I only fly them...I do not have a lot of technical data as others have kindly given you here....but as to flying a Diesel/FADEC engine, I will help if I can.
