Anyone try x rings in there hit and miss engine from China?
I was reading about the claimed advantage over o-rings and it sounds good.
-lower drag
- good high speed performance
- not prone to twist issues
- less compression force needed to create a seal
-excellent in reciprocating applications
Low drag is of special interest to me, it may allow our engines to coast longer in the "miss" stage.
I need new/better o-rings in my Enjomor engine, when I determine the size I hope to place an order for x rings as well as o-rings and plan to do a test, might be fun!
Photo is what the cross section of an x ring looks like, they put the parting line down in the groove so the lobes offer more perfect seal in theory.
