Diesel aircraft engines and are the light jets pushing out the twins?

R.,

What has happened to the development of the diesel aircraft
engines? As far as I have seen, only Diamond has a production
aircraft with diesel engines (they flew one across the Atlantic,
with 5.76 gph).


In the European market, Diamond offers both the single-engine DA40 and
the DA42 twin with Thielert Centurion engines. More than 100 of these
engines are flying. in the US, only the DA42 is offered. Also, Thielert
in Europe offers retrofit kits for Cessna 172s and Piper Warriors. Of
those, 30 or so are flying.

All other diesels I know of are not yet available in a certified kit,
although by now the sma retrofit to the 182 might be available.
