to see whether the Subary flat-four diesel finds any aircraft
applications.

Are there any diesel aer-engines, or diesel car engines frequently used
in aircraft? I had the impression that diesel aero-engines died with
airships and the Junkers 86, but I'm always willing to learn....

Yup, Thielert engines are used by Diamond aircraft.

Check out Diamond Aircraft
http://www.diamondaircraft.com/aircraft/index.php

They had problems with their engine supplier going bankrupt, and were left
without support for their engines, but have gotten another engine program
going quickly. I can't recall if it was the Mercedes engine that went belly
up, or if they are going to a Mercedes engine.

Forget the aquisition cost - it's the maintenance/rebuild that kills
you. Certified parts are pricey. An average auto conversion can be
zero timed for the cost of doing one jug on a "real" aircraft engine.

Right. You could overhaul to new a auto engine conversion every 500 hours,
and still be money ahead.

In reality, you probably will be able to go to well over 2,000 hours with a
auto engine that has been flown frequently, at reasonable power outputs,
without problems.

Those 912s stand up VERY well but the price!!!!!!!

That's the word on the street, but, the company!

I just will not allow myself to get into an aircraft with an engine made by
a company I trust so little.

It sure limits your (read my) choices in the light sport aircraft field.

The anti-auto (or truck) engine crowd will never admit that one of these
engines would work well, and be reliable in an airplane. I get so tired of
the "they never run at full output in autos" way of thinking.

I still would rather get in an auto engine conversion airplane that has had
the bugs worked out, than any airplane with a rotax engine of any size.

There is a fundamental problem, any auto engine is designed to deliver
purely rotational power from the crankshaft to the transmission.
In aero applications the prop is applying the entire power of the engine
trying to pull the crankshaft forward out of the block. That needs some
serious thrust bearings which auto engines simply do not have.
Which is a TOTAL nonissue on most auto conversions

Get used to it.

He's wrong a lot.

WERE. What is the status since Thielert's bankrupsy?

I have a friend who has adapted a V8 engine into his Long Eze. It is
direct
drive with no PSRU. He has flown cross country from CA to Oshkosh
several times. As far as I can tell he has not had any engine problems.

Wow, I would like to see that set-up. Did he have to move the fire wall
forward, for ballance?

I would not use any auto engine, without at least an additional bearing
for thrust added to the crank. I had a 350 chevy crank in a van that was
25 thousands over spec, in end slop. That was without any thrust on the
engine.

Bombardier is a very highly regarded company - most of it's products
are in the top 10% of their competition - but ANY 2 stroke engine, to
me, is suspect.
I know, in theory they are almost bulletproof because they have so few
moving parts - but in practice they are fragine.

Heck, I won't even take my chainsaw up a ladder, why would I fly
behind one????
TBO on the 2 stroke stuff is PITIFUL.

Diamond are now using Austro diesel engines.

AFAIK Centurian are now building Thielert engines again but ICBW.
