Clearance volume usually refers to the volume above the piston(to the top of the block) if the piston is receased( .30'' in the hole). + vavle relief in cc's+ the volume of the head gasket.
This is the ratio between the total volume to the clearance volume in IC engines
Compression Ratio is the ratio between the original volume and the compressed volume in combustion chamber. The compression ratio is denoted as CR. It is the measure of how much air-fuel mixture is compressed during the compression stroke in the case of the gasoline engine (in the case of the diesel engine only air is compressed. Compression ratio is found by dividing the volume of stroke of the cylinder (swept volume) and clearance volume when the piston is at BDC by the volume when the piston is at TDC (ie clearance volume). Compression ratio= (Swept volume + Clearance volume) / Clearance volume. For example engine has a Swept volume of 700 cc. It has clearance volume 50 cc. Compression ratio= (700 + 80) / 80 =9.75: 1 It means Air fuel mixture is compressed to 1/9.75 of its original volume during compression stroke.
The volume occupied by the cylinder when the piston is at top dead centre is called clearence valume.
The clearance ratio for a single stage compressor is the ratio of the volume clearance at the end of the suction stroke to the volume displaced by the piston during the compression stroke. It is important to minimize clearance ratio to improve compressor efficiency. A lower clearance ratio indicates less trapped volume and better performance of the compressor.
clearance volume decreases the volumetric effienfy of compressor.the clearance volume should not be too less or too more.

Well if you know the displacement, number of cylinders, and geometric compression ratio, you have everything you need to figure out the clearance volume. Compression Ratio = (Displacement + Clearance Volume)/(Clearance Volume) - rearranged gives: clearance volume = displacement/(comp. ratio -1). A reasonable assumption of compression ratio on a modern F1 engine is somewhere around 12-13.5:1, I would say. So assume 12.8:1 compression ratio. You also now that each cylinder displaces 2400cc/8 = 300cc. So, clearance volume = ( 300cc ) / ( 12.8 - 1) = 25.42cc That should get you in the ballpark anyway.
