I am confused to the apparently exaggerated term
"continuous power".
My interpretation of continuous power would be an
approximate cruise setting for 24hrs/day.
General aviation application is usually less than 5 hrs
at a time at that setting.
Interpolation, with all factors, may show aviation piston
engines to come up a bit less than superlative.

And just think of all the AD's people can enjoy on 60+ year
old engines with aircraft owners performing life testing
for the factories that still do not have it right!
Archie the grouch.

Yes but until the wankel rotary Archie this was all we had :-)

Some of those 60+ year old engines have been overhauled
four or five times. At that point I am not surprised they
are junk. The life testing comment is not all that fair.
There are a lot of aircraft engines in training and daily
use that go to TBO. You just don't hear about them.
Flying fifty hours a year is not exactly good
for your engine.

I think an electronic fuel injection system would reduce the
possibilty of pilot error on the mixture and extend
the life of the exhaust valves. Rumor has it that Cessna
is working on such a system that controls everything;
prop, mixture, and ignition.
