I want to know how to calculate engine idle air requirement.
Engine rpm = 1200 rpm = RPM
Rev/cyle = 2
Engine capacity = 395 cc = 0.395 Lit = L
Volumetric Efficiency = 90% = VE
Then VAF (Volume of Air Flow) is,
VAF = (L/28.317) x (RPM/2) x VE.
I want o know what is the meaning for 28.317
Can anyone tell be the derivation for it?
