BTW can anybody tell me why my air passages in this rotor housing
are a bad idea? This is a quiz.

Paul Lamar


They allow high pressure combustion gases to pass back to the intake
 side. This would cause preignition. BIG no no!

Dale Davies

Possibly but there is one other problem.

Paul Lamar

Compression pressure bleedoff and out the exhaust. Low cylinder
pressure and high exhaust emissions. Dale Davies

Not exactly.

What do you mean "out the exhaust." ?

Paul Lamar


It will blow the combustion cycle back into the previous chamber as
apex passes inlet to bypass. And the timing would be static. The
rotor design stays with the combustion

Kurt Emerson

Well yes but that is not what I had in mind. There is another factor
in play here. Can anybody think what that is?

Paul Lamar



That the passage would cause that area to be even hotter than it already is, and its already a problem area.

Dan Gorsline


Not yet :-) That is not it.

It is a well known problem you should know about.
