Rotor material
I have a collection of pistons and a rotor from an early 1.0L (10A?) on display on my workbench, just to create discussion and curiosity. The rotor appears to be made out of cast iron and is quite heavy. I was wondering what material the rotors are made out of in the new Renesis engine. Are they aluminum, still cast iron or... ?

Cast....
Still cast iron, but a little thinner.

I never understood. What is the issue with casting the rotors in aluminum? is there some kind of detriment to the rotor being too soft, or is this a cost issue, etc...

Just the same casting technique they never changed, it has worked before it'll work now. Although improvements have been made, but I agree that the use of lighter weight alloys/metals would be beneficial. Most likely in race applications, higher RPM, less stress on E-shaft. I made a post about it in the "advanced renesis tech" thread.
Does anyone know if the use of lighter/different alloys for the rotary engine can change the resonance frequency? So it can be revved higher than ~13k. ________ Nonude teen models |
Aluminum isn't as strong as steel or cast iron. There are people that have dented and cracked rotor faces. Aluminum couldn't take that much abuse.
Cost is always an issue. |
