Solving For Engine Piston Deck Volume

note: PDV = (Piston Deck Volume) + (Piston Dome Effective Volume)

## Inputs:

BORE
distance to piston distance (DPD)
volume of piston depressions (VPD)
volume of piston bumps (VPB)

## Conversions:

BORE
= 0
= 0
inch
distance to piston distance (DPD)
= 0
= 0
inch
volume of piston depressions (VPD)
= 0
= 0
inch^3
volume of piston bumps (VPB)
= 0
= 0
inch^3

## Solution:

piston deck volume (PDV)
= 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
