Paul. I worked with Peter Hoffbauer 25 years ago. He's the genuine
article. Their series A funding is complete.  Bill Gates is a major
backer. Don runkle is CEO

It is essentially the same as a 1930's Junkers Jumo 2 stroke
diesel with the  same 2 stroke port timing problems. Therein lie
the problems.

Jeff Spitzer, chief engineer at GA Aircraft Division SD, built a scaled
down copy about ten years ago and had it at OSH. It was rejected by the
AF in favor of a turbo Rotax 914. Even the Germans gave up on it
around 1940.

Here are some Jumo pictures. Also a much smaller version called
the Gemini I saw at Aero in Friedrichshaven in 2009.

Napier built a large 3 crankshaft version called the Deltic. Widely
used in locomotives and boats.

Bill Gates should have checked with me :)

Supertec in Germany are building a high compression diesel version of
the Wankel. A turbo compound of that engine would be unbeatable.

Paul, Reeves and all readers....

The CEO of Eco-Motors is now on Transonic Combustions Board.

http://www.greencarcongress.com/2010/05/runkle-20100520.html

Khosla Ventures is putting money into both. Tangent to this is Bob Lutz has
joined Transonic's Board

http://earth2tech.com/2010/05/24/bob-lutz-joins-startup-transonic-combustions-board/

Having these heavy hitters affiliated with these programs is no guarantee of
success, this is not a judgement on the program, but look at some of the
large dollar venture capital and the names behind it that where on the
Eclipse Jet Program.

This maybe throwing the long ball in the arena of the "Ug-known", but can one
ask will they potentially add the Transonic Injection system to the
Eco-Motors Engine(given the comments of the port timing and injecting fuel
into this type of engine).

My Best,
Anthony

Direct injection or anything else like it would do no good.
Two cycle engines have what is called a scavenging ratio which is the
ratio of fresh air relative to residual exhaust gas. There
is no way around it so far, particularly in an opposed piston configuration,
and that is why 2 cycle diesel engines have more or less disappeared.

IMHO the best 2 cycle diesel engine ever was the GM roots blown
modular V engines with dual exhaust valves in the head called Uniflow
scavenging. Some were turbo charged as well. It was very competitive
for years with four stroke diesels but emission rule considerations
finally killed it.

CEO types and wealthy people are not always well educated when it
comes to technology. A slick person, perhaps a bit knowledgeable in
one discipline, can frequently pull the wool over their eyes :)
