Well, if you can believe what Mr. Zoche says, his 300 HP engine only weighs 271 lbs which lighter than any gas engine at the same HP and probably any at 200HP. His design is an old fashion radial with air cooling fins. 11.13 gal/hr is pretty damn precise numbers if he doesn't have a working engine. I am frustrated that he's been sitting on this (for over 15 years)if it truly has the stats he claims. http://www.zoche.de/specs.html. The size is a compact, 25.5" W x 25.5" H x 32.9" L. Comp. ratio 17 to 1.  He's either a fantastic liar or crazy for not having it certified somewhere.

Jay and all,

until there are a few light weight diesels on the market to choose from.

The problem is, a light weight diesel is by no means lighter than a light weight gas engine. A diesel is heavier by design : more pressure in the combustion chambers, more torque variations, etc.

Truly a miracle engine, which has been almost certified for the past 15 years according to the owner/developer.

"Almost certified" engines are almost suitable for your airplane. Your airplane will almost fly Wink

You don't think, maybe, he is being paid to keep a lid on it by one of the 'established' aircraft powerplant manufacturers ? ... or am I just too sceptical ?

Rick,

You might be thinking of the Wilksch engine ( www.wilksch.com/).

Got to be something like that, someone is paying him to keep it off the market. I would think he'd make much more money though if he'd just release the thing to the general public as it would be in huge demand. He's even got the prototype in a video that is so quiet it was amazing. Most of the noise came from the propeller blades. Patent the silly thing and get it on the market, because there's nothing remotely close to that diesel now. It makes the Thielert Centurian  and DeltaHawks engines looks like heavy beasts, the likes of something the Flintstones would use if they could fly.

I've been watching this thing for 15 years. If something sounds too
good to be true it probably is!! I did hear that he is getting some
kind of government financing while in development. So why finish
development? Also, maybe the thing really can't do what he is promising
so he just keeps on promising and living off his government.

Much of the above is hearsay, but I certainly would say, 'Don't hold
your breath for this engine!'

Actually I was thinking of the Gemini 100.

The following is a web site that talks about the engine
