- Thielert Centurion 4.0:.......350 hp http://www.centurion-engines.com

The only one out of this list, that is not flying jet, is the WAM160, but there are some engines that are going to be installed in RV 9's in the UK soon.

I have left out the SMART Diesel powered Ultralight (70 hp?), because I could not find a link to it and I left out ZOCHE because it looks like they are living on the grants they get from the European Union to keep on "developing". I do not believe they will ever bring their engines (75 hp, 150 hp and 300 hp) in production. Maybe its the competitors or "the Avgas lobby" that are paying them money to stay off the market, who knows?

Now, with Avgas prices of approx. (Belgium): 2,05 Eur/lt (10,10 $/gal) and the cheapest form of Diesel at 0,52 Eur/lt (2,55 $/gal) , you can imagine why its interesting to go for a diesel engine in Europe. The fuel cost may be somewhere around 30% of that of Avgas!! After 2.400 (TBR of the Centurion) that means, lets say at 20 lt/hr, a difference of somthing like 70.000 Eur (91.000 $) So......... thats why ! I hope its clear to all now.
If the diesel engine would be heavier than an Avgas engine (if!!), that means the empty weight goes up and the usefull load goes down, no problem for us skinny Europeans! But, as has been addressed here many times before, because the diesel uses less fuel, you have to carry less to go the same distance and this will make up a lot (if not all) of the weight penalty.

I am also looking into a Mogas burner at the moment. It seems that a lot of small airfields are also catering for Mogas these days. Still saves 50% and if unavailable you can always fill-up with Avgas to get you back home.

I don't know much about it but isn't there another engine? I snipped this out of a post on another forum:
<snip>
From the aviation diesel sector, my money is on the DAIR. It may be only 100HP now, but just with the addition of an intercooler it can be boosted to 135HP, just enough for a basic Cozy with a CS prop. They are cheaper than Centurion and they are happy to work with homebuilders. <snip>

The poster is actually trying a home-brew of a Mitsubishi Colt turbodiesel in a Cozy III.

I don't know much about them either but on the first page of goole search lead to these sites:

We haven't heard anything more about the new Toyota engine built in Eastern Europe, I believe with a designation something like D2.2. It sounded great, Aluminum sleeved block and 16:1 compression. (it's been a few months since I read about it but it should be on the road by now.)
There are also some good looking PRSU's out that should work with the right coupling scheme. I think the PRSU should have it's own oil pump, high pressure lubricant and cooling system. like the Canadian CAM unit.

it is used in Lexus and Toyota products in Europe and designated:

D-4D, in line 4 cylinders, 2.2 liter, 180HP, aluminum head and block, 160 kg ~ 350 lbs.

An acquantaince living in Greece has been on the lookout for one throughout europe for an auto conversion into the Cozy III mentioned earlier but no joy so has decided to go with the smaller Mitsu ... but the D4D was/is his first choice [he plans on using one some time in the future].

cheers,

John,
This does indeed seem to be a new comer in the field. The interesting thing about this engine is that it is a dual crank engine with the cranks timed so that the opposing pistons nearly meet in the middle of a common (between 2 pistons) bore. Again, this is a 4 piston engine with 2 cylinders and 2 cranks. This is identical in configuration to a Fairbanks-Morse? locomotive engine. It was a huge 12 piston (if I remember correctly) 6 cylinder 2 cranks. It was VERY efficient, in fact, again working from memory it was the record BSFC holding diesel until some of these huge ship engines started to be built.
Very interesting!
