Rotary Engine Volume Flow Calculation
Rotary Engine Volume Flow Calculation
(OP)
I know how to calculate the volume flow of a 4-stroke piston engine, Engine Speed x Displacement x Volumetric Efficiency / 2.
How can a similiar calculation be done for a Wankel engine? I've read the previous topics on this board and scoured Google but came with no satisfactory results.

Perhaps you have this number already. You could then calculate air flow the same as with a recip.
Now for the qualification: I looked through my notes and could not find anything specific, but I think this method should be valid. I haven't tried it however.

The rotor also spins at 1/3 the output shaft speed, so
Flow= Output Shaft Speed x Rated Displacement x Volumetric Efficiency x 2/3
This seems to match well with the dyno numbers.
