- DAC Ranger:........................90 hp http://www.dac-ranger.nl
- Wilksch WAM 120:............120 hp http://www.wilksch.com
- Thielert Centurion 1.7:.......135 hp http://www.centurion-engines.com
- Wilksch WAM 160:............160 hp http://www.wilksch.com
- SMA SR 305:.....................200 hp http://smaengines.com
- 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:

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.
