Thanks guys for your replies,
The problem is, my project is a design study and performance comparison of installing a diesel engines into light aircraft. There are 7 manufacturers at the moment. Wilksch airmotive have successfully test flown a Europa with 120hp diesel. Diesel engines have many advantages over piston engines. I know the range is increased but I need to know by what extent. My two case studies involve:
-The 120hp diesel engine compared to the 80hp Rotax912 installed in the europa
-the zoche diesel engine into the islander.
It is a really interesting project however I cannot get a hold of a lot of info - esp on the diesel engines as the manufacturers have to be fairly secretive at this stage and therefore i am having to make intelligent guesses.
