Hi Paul,

glad you made it back and curious on all the news from the Mazda-Universe!

Recently someone mentioned that on the 13B or Renesis size engine the main bearing loads go nearly t ozero around 6500 rpm.
I think you posted a graph to this.
I thought I saved this post, but can't find it.

Could you please point me to that info again and also WHY the loads seem to disappear?

Thanks,

Thomas J.

They don't go to zero but the combustion force tends to cancel the centrifugal force
depending on the weight of the rotors. It varies from year to year. This is
published in Mazda SAE papers or the book Rotary Engine. The equivalent number
is about 3600 RPM for a piston engine. Also this is the RPM limitation to the rotary.
