carbon-carbon 2 stroke piston/cylinder ringless
« on: January 27, 2011, 09:05:23 PM »
Ringless. Minimum piston/cylinder expansion differential. 30% lighter reciprocating mass. High thermal loads. Longer lasting. HIGH RPM.

What is required to make a piston and cylinder from carbon-carbon?

Discuss...
2 strokes...
because 2 extra strokes and 35 extra pounds won't make you corner better.

I don't know what it will take but I know I like it, that article mentioned the proposed motor would be AIR COOLED     ;D
aaahhhhh yes, I remember the good old days

I would think that it would be un-realistically expensive to start with !!

Sounds like what designers have tried with ceramics.
I like the bit about less piston rocking on four strokes.
But wouldn't they need skirts first. ;)
