Hi Paul and group,

Here is an update from the link in your web site on ceramic engine.

Update as of September 2008
Appropriate data for an equivalent /metal/ Wankel engine is being
currently generated which should act as baseline data for comparing
with data yet to be generated from our /ceramic/ Wankel engine. A
prototype CeTZP ceramic Wankel rotor has been made to specification. A
CeTZP ceramic Wankel housing and CeTZP ceramic side plates are being
commissioned. Preliminary tests for the ceramic Wankel engine should be
carried out at our test facilities once the ceramic components are
assembled. When, we do not know. This is a novel technology and we want
to get it right.

This sounds pretty good.

"The Phase I study of the turbocharged "Adiabatic Wankel-Type Rotary
Engine"indicated progressive performance improvements in Wankel rotary
engines when the combustion chamber components were insulated.  The
adiabatic Wankel engine with the advanced concepts: turbocompounding, higher
compression ratio, reduced leakage, and faster combustion could decrease the
specific fuel consumption by 25% and increase power output by 34%.  The
elimination of the cooling system can give another 5% reduction due to
cooling system components.  A total possible improvement of 30% in
performance and a 15% reduction in specific weight on an installed basis
could provide the next spring-board for the adiabatic Wankel rotary engine
to compete in the worldwide aircraft, automotive, industrial, and other
power plant markets."


One thing they missed is the lower density of a ceramic rotor will
allow upping the max revolutions to generate even more power per pound and power per cubic foot of engine.
