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

I think I have that PL design too. But I
didn’t think it included any inner packing of any sort?

I have a design of the “late Paul
Lamar“ somewhere in my archives.
Don’t know if i may share it on
the group ?
That was of a proposed design of
a freeflow muffler for rotaryengines.
He shared it with all the people
on the group.
Don’t know if it was patented?
So where can we find
the proposed “specialist in exhaust systems”
that it suggests? For our applications that
would probably be someone on this list!?

Designing
a muffler for a Mazda rotary
engine requires taking into
account several factors,
including:
-
Engine
specifications: The
muffler must be
compatible with the size
and output of the
engine.
-
Noise
reduction: The muffler
should reduce engine
noise to an acceptable
level, while also
allowing the engine to
function efficiently.
-
Performance:
The muffler should not
restrict exhaust flow
and impact engine
performance.
-
Durability:
The muffler must be
durable and withstand
the high temperatures
and vibration generated
by the rotary engine.
A muffler design for a Mazda rotary engine could include a straight-through perforated core, surrounded by sound-deadening materials such 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 muffler from high temperatures.
These are general guidelines and the exact design may vary based on specific engine and performance requirements. Consulting with a specialist in exhaust systems is recommended
to ensure a muffler that is optimized for your specific engine and application.
You're welcome.
