Hi, I am currently working on software to estimate Power and torque output of an engine by user input information such as; Bore, Stroke, Cylinders, intake flow rate, head flow rate, Boost, valves per cylinder, cam duration and lift, Ignition timing and quite a few more. So far I have gotten to a point that i am struggling to estimate Volumetric efficiency at a given RPM. It automatically calculates the Theoretical CFM at all RPM. The issue I am having is how to estimate the ACTUAL flow rate into the cylinders to use to calculate VE. As of right now, my Torque will just continually rise past 10000 rpm because of the assumed 1.0 VE at all times(this can not happen). Any help would be greatly appreciated. Please take it easy on me as i am new to engineering and this forum as well. THANKS!
