Web20 de nov. de 2024 · Step 7 – Determine the compression ratio: Use the formula below to compute the compression ratio. Compression ratio = { (swept volume + clearance volume) / clearance volume} Swept volume = (π) x (bore radius squared) x (exposed cylinder height). Clearance volume = 0.000cc [ (bore/2)2 x π x deck height x 16.387].
