It is not post- matura, (finishing secondary scool / wikipedia) I think. I´m studying in collage, s.o. If you think that the complication for diploma is not enaugh... The information is hard to get, because there isn´t no more information on engine manufacters homepage besides engine data. On
www.dieselair.com is a newsletter, like "Cessna 172 has new diesel engine mounted or there is a new engine coming up". And, maybe some on you have flown with diesel engine airplanes. I need more info, and more specifically, certain facts about airplanes, then I can put all things together.
Besides, I´m doing diploma for my first time and I only asked for little help, if the thread is not in topic then you can put it in lock.
