It will also estimate a dynamic effective compression ratio taking into account the cam timing and rod ratio. (considers cam timing and rod ratio) This calculator will give you the proper compression ratio with a known piston head volume. When this happens the valve reliefs and the pop-up are approximately equal in value. On the piston calculator many times you will come up with a piston head volume that approaches zero. If you do not have the exact gasket bore use the cylinder bore in its place. With some pistons this flat area may be very small (example: Chrysler Hemi is only a line at zero deck). Do not measure to the top of the pop-up or the bottom of a dish.

Deck Clearance.Deck clearance should be measured from the top of the block to the flat portion of the piston.

Located above each picture in the KB Catalog is the value for the piston head volume shown in positive or negative numbers. Pistons with a dish or pistons below deck increase chamber volume and receive a positive value. Pistons with pop-ups or pistons sticking out above the deck will reduce chamber volume and will usually require a negative number. Negative numbers indicate a reduction in cylinder head volume. Values for Piston Head Volume and Deck Clearance can be entered as both positive or negative values.

Piston Head Volume and Deck Clearance.

While these calculators will calculate out to six (6) decimal places, they will round to three (3) decimal places when they are displayed, and any figures you enter will also be rounded to three (3) places when the results are displayed.

Q C = compressed air flow (m 3/s, cfm) Example - Converting Compressed Air Volume Flow to Free Air Volume FlowĪ compressed air volume flow of 10 acfm (actual cfm) at 100 psig must be multiplied with Compression Ratio approximately 8 to estimate the volume of free air at atmospheric pressure.Įxample - Converting Free Air Volume Flow to Compressed Air Volume FlowĪ free air volume flow of 1 m 3/s is compressed to 10 bar (gauge) and must be divided with Compression Ratio approximately 11 to estimate the volume of compressed air. The compression ratio of free air - to compressed air, is indicated in the diagram below.Ĭonverting Compressed Air Volume Flow to Free Air Volume FlowĪ compressed air volume flow can be converted to a free air volume flow by using the equation

P s = suction absolute pressure (bar abs, psia) P d = discharge absolute pressure (bar abs, psia) Free air is air at ambient conditions at a specific location whereĬompression Ratio is based on the Ideal Gas Law and is the ratio between Discharge Pressure Absolute and Suction Pressure Absolute.
