Solving For Engine Volumetric Efficiency

Inputs:

cubic feet per minute (CFM)
unitless
cubic inch displacement (CID)
unitless
revolutions per minute (RPM)
unitless

Conversions:

cubic feet per minute (CFM)
= 0
= 0
cubic inch displacement (CID)
= 0
= 0
revolutions per minute (RPM)
= 0
= 0

Solution:

Volumetric Efficiency (VE)
= NOT CALCULATED

Where
 VE = volumetric efficiency CFM = engine air flow rate - cubic feet per minute CID = engine displacement, size or volume - cubic inches RPM = engine speed - revolutions per minute NOC = number of cylinders BORE = length STROKE = length HGV = head gasket volume HGCT = head gasket compressed thickness PDV = piston deck volume DPD = deck to piston distance VPD = volume of piston depressions VPB = volume of piston bumps SV = swept volume CR = compression ratio CCV = combustion chamber volume ISH = injector size per horsepower HP = horsepower
