Since the PL site doesn't have any of the old informa= tion, it would be great if somebody could post that here.

That was of a proposed design of a freeflow muffler f= or rotaryengines.

He shared it with all the people on the group.

Don=E2=80=99t know if it was patented?

Let me know

Designing a muffler for a Mazda rotary engine requires takin= g into account several factors, including:

  1. Engine specifications: The muffler must be compatible with the size and ou= tput of the engine.
  1. Noise reduction: The muffler should reduce engine noise to an acceptable l= evel, while also allowing the engine to function efficiently.
  1. Performance: The muffler should not restrict exhaust flow and impact engin= e performance.
  1. Durability: The muffler must be durable and withstand the high temperature= s and vibration generated by the rotary engine.

A muffler design for a Mazda rotary engine could include a s= traight-through perforated core, surrounded by sound-deadening materials suc= h as fiberglass or ceramic wool. The muffler should be mounted using flexible connections to reduce vibration and ensure= a secure fit. Additionally, heat shields could be used to protect the muffl= er from high temperatures.

These are general guidelines and the exact design may vary b= ased on specific engine and performance requirements. Consulting with a spec= ialist in exhaust systems is recommended to ensure a muffler that is optimized for your specific engine and applicat= ion.


You're welcome.
