I was just wondering how we can find out the efficiency of a rotary engine?
Obvious, it is more efficient than a gasoline/diesel engine.For example the RX8 on 1.3 L in 2 rotors get 250 hp which is quite impressive for that capacity,also it works in 4 stroke,and the power to weight ratio is good.The only disadvantage would be the pollution that occurs, due to emmisions.
From my knowledge the diesel is more efficient than a gasoline due it's bigger compression ratio , hence more torque at lower revs.This can be proven thermodinamically using the efficiency formulas that imply compression ratio.
I am curious what types of calculations would be required to find out the efficiency of such engine , because I would like to plot a Power output(HP) vs Tq(torque) diagram,on different revs.
