One thing that everyone should keep in mind, is that automotive diesels
run on diesel fuel, and everyone wanting diesel engines for their
airplanes is going to want to use jet fuel.

Jet fuel does not have the good lubricating properties that diesel fuel
has, and may tend to wear out the automotive fuel pumps in short order.

I read somewhere that Thielert spent half of what they spent on
modifications to the engine, in designing a fuel pump that would be
durable enough.

Something to keep in mind.

As of a few months ago, lubricity was a very serious problem in Ultra Low
Sulpher Diesel fuel, because the quickly implemented refining process tended
to strip most of the lubricants from the fuel. I have no idea whether that
caused it to have better, or worse, lubricity than Jet-A, but there are a
couple of high pressure lubricants offered specifically to solve the
problem--plus some "home brew" fixes.

BTW, the solution mentioned elsewhere in this thread is new to me; but
diesel airport vehicles have run on Jet-A as long as I can recall and AFAIK
all of the military Hummers are specified as diesel.

Comments???
