Hi, I don't remember if this is posted already, but here it is...

This was supposed to be a part of Abrams upgrade package:
http://www.engineeringtv.com/video/TARDEC-Auxiliary-Power-Unit-for

12kW, 330cc, with pre chamber (?) and glow plug. Manufacturer is
Patrick Power Products: http://www.patpower.com/

With quick search I couldn't find test results. Plenty of talk on
TARDEC about using fuel cells on M1, but not a word about how this
one turned out.

Cheers, Petri


Probably classified as secret. Here are some pictures of the Pats
engine. Some I took at a show as I recall.

In the CFD animation (anim_roto3.gif) it shows an offset
chamber/depresion in the rotor face. It reminds me of a NACA scoop. This
is suppose to create more torque during the expansion cycle. I know this
idea has been discussed but don't recall the merits.

Are you aware if anyone has tested this concept?
Are you aware of any testing Mazda may have done on offset combustion
chamber in the rotary engine?

Yes Mazda did some work on that as well as some others.

Wrong answer :)

You get an F :)

Obviously you did not do your homework :)

Stock new and new  Ianette silicon nitride seals are crowned.
The use of after market straight seals cause a 10% loss in compression.
