Premier aircraft is marketing their diesel 172 . The price for new motor panel and total upgrade will be 289 K ,not bad when you figure it all out. I can't afford one. They will rep owner existing 172 for 95 k. Should make some flight schools happy.

I think I'll just buy 10 older 172s instead.

It's a shame that they screwed the market like that. People will be gun shy.
When are Lycoming or Continental going to start making Diesel engines?

Well, according to the press info Continental does have a Diesel aircraft engine TD-300 which is in production and which was certified about 10 months ago.

They are making them.
You can buy a diesel 182 from Cessna and Continental diesel right now. It is based on SMA diesel, but Conti has bought all the rights and make it themselves.
Lycoming is making a diesel for drones. It's not certified for manned aircraft but it gains flight hours.

I think Cessna and Diamond have the right idea with their diesel engines for new aircraft. A diesel would represent the only reason why a new aircraft would offer me a benefit over a used one. I think Cirrus will jump on the bandwagon eventually. With Continental backing it, it should be easier to sell, and a safer bet.
Continental bought the theilert line ,so the engine is supported by continental.
Diesels use jet fuel.

You know, there's a much bigger world than just Amerrrrrrica out there. And in that world, jet fuel is available while avgas isn't. There's where those diesel 182s are selling.
But even in the U.S., jet fuel is not that hard to find.
Didn't know that.
Why are they called diesels then? Couldn't run jet-a in my duramax I'd bet.

Maybe not in a new computerized diesel car but the pure computer everything diesels burn jet a just fine. Used to be a pilot that ran a diesel rabbit on sumped jet a, I used to burn jet a in a kerosene heater. all pretty much the same stuff.

I don't know of any JT-As yet, but the old pre-NXT 182s and an NXT are flying in Russia, where availability of avgas is an extreme problem, according to forums anyway.
Here's a message from 2012 that I remember, the aircraft had 400 hours TTAE back then and lived through the FADEC burning out in thunderstorm and a blown injector:
http://saon.ru/forum/viewtopic.php?p=112507#p112507
One problem for 182, however, is that it's a single and some of CIS countries have red tape related to the use of singles anywhere outside of basic training (e.g. for sightseeing). So we have Armenians clinging to DA-42, for instance.
Update: here's another fun example, that was sold last year:
http://www.cessna.spb.ru/news/2008-11-19/02.jpg
It's an 1984 (!) aircraft with SMA FF STC by Tule. The diesel was overhauled in 2007, 1500 TTAF 100 SNEW at sale time, now flying in revenue service. As you can see, Russians do love them some old junk.

Diesel is supposed to be capitalized. Last name of Karl Diesel.
Now you have learned even more about your truck motor.
Continental already is. The 4 cyl 230hp is certified I thought I read. The 350hp 6 Cyl is "in the process"

Diesel refers to the thermodynamic design of the engine, not the name of the fuel burned.
https://en.wikipedia.org/wiki/Diesel_cycle
"The Diesel cycle is the thermodynamic cycle which approximates the pressure and volume of the combustion chamber of the Diesel engine, invented by Rudolph Diesel in 1897. It is assumed to have constant pressure during the first part of the "combustion" phase (V_{2} to V_{3} in the diagram, below). This is an idealized mathematical model: real physical Diesels do have an increase in pressure during this period, but it is less pronounced than in the Otto cycle. The idealized Otto cycle of a gasoline engine approximates constant volume during that phase, generating more of a spike in a p-V diagram.
...
The Diesel cycle is a combustion process of a reciprocating internal combustion engine. In it, fuel is ignited by heat generated by compressing air in the combustion chamber, into which fuel is injected. This is in contrast to igniting it with a spark plug as in the Otto cycle (four-stroke/petrol) engine."
Sure you can. Depending on the pump type you might need to do a lubrication mod. We've run JetA in many Diesels.

As has been said, it has to do with the cycle rather than the fuel that's used.
If you put Jet-A in your Duramax, it probably wouldn't run very well. Jet-A has some different properties. Cetane isn't controlled, lubricity is different, etc. It doesn't make a great fuel for a diesel engine, but it works well enough.
The aircraft diesels have been modified specifically to run well on Jet-A, and they do. The modifications include some hardware changes to the fuel system as well as a specialized FADEC that is programmed properly for running on Jet-A.
Because they are compression ignition engines. Not only can you run jet in a Diesel engine, you can run turbines on diesel fuel if you wanted to.
I'm curious why you say that? I've done testing on diesels running jet and they never seemed to run funny to me. We always used a special lubricant in the fuel during these tests, the primary thing we were doing were fuel system tests.
I've run jet in my powerstroke and cummins with no issues.

Pre-takeoff checklist
The US military went to straight jet fuel years ago for almost all equipment- from the trucks to the tanks to the aircraft. No more MOGAS or diesel. All the diesel engines run JP-8.

I say it from my experience.
Yes, I know. And they also have the hardware for it.
I believe Diesel's first name was Rudolf.

All the other engineers used to laugh and call him names, poor Rudolf with his sparkplug less motor never got to play in any engineer games...

There are only four J182Ts on the FAA register (plus the experimental prototype shown in the ad). All are still registered to Cessna.
