Current diesel engine options for C172

[baleares]

What are the current diesel / A1 engines available to fit in older Cessna 172 N aircraft ?

Certified or Experimental?

The most common conversion available will be the Centurion, either 135hp or 155hp from now Continental (ex Thielert - conversion of Mercedes Benz A-class engine for aviation use). Disadvantage of these engines - there is no TBO, only TBR (no overhaul options, only replacement, and the 155hp has only 1200 hours TBR) and not everybody is amused by FADEC flying. If the N is Experimental, conversion to VW Diesel engines may be also an option.

Many thanks. Would you know if these engines just slot right in without any modifications to mountings etc..?

Hardly,

Lycoming:




Centurion:



Pretty much everything forward of the firewall beyond the nose gear is replaced. Base Price around $100,000 American.

Great pictures, thanks. I had not considered how much the mounting would have to be reorganised.

Besides Centurion are there any other engines in development that will fit a Cessna - hopefully with a longer TBO/TBR! ?
