Almost. The local A&P community college here runs an STC'd diesel
172. The engine is made in Germany. They run it on French Fries.

The engine is made by Thielert in Germany. It is a modified
Mercedes common-rail diesel engine.

For more information, go to http://www.centurion-engines.com/.

By the way, it runs on the big-airplane food: JET-A1.

I am personally aware of two such planes (Thielert-powered C-172's)
which have been removed from service due to unexpected, and as yet
unexplained engine stoppages. . . Anyone else heard of this?


Thielert has had its portion of new-design woes:

- problems in fuel and cooling plumbing,
- gearbox / clutch problems,
- broken high-pressure pumps.

AFAIK, no real problems with the most feared component,
FADEC (Full Authority Digital Engine Control).

One twin with Thielerts came down immediately after take-off
in Germany, when its electrical system collapsed. The engines
had been started with external power and the battery was not
in system at all. The procedure was prohibited in the operation
manual. The electrical systems have been changed so that it
is not anymore possible to repeat the preformance. This was
actually more an airframe problem than an engine problem.



Bull****. Engine installation problem.

ME,? I want a big, honkin' 350 to 360 HP that will fit nicely into
the Deb and cost about as much as a new IO-360:-))

Can you tell the hours are getting close to TBO?

Please explain - what is the difference with an airframe
problem and an engine installation problem here?

As far as I understand, the electrical system design is
an airframe part.

No, it's an electrical system part. Airframe parts are wings and what
not....
