Compression rtio of a piston
WebJul 11, 2024 · Compression Height (compression distance) is the dimension from the flat top of the piston crown (not inclusive of dome or dish) to the centerline of the piston pin. This should always be referred to as the pin height to avoid confusion. We often say an engine has some specified compression ratio, such as 10:1 compression for example. WebJan 25, 2024 · The compressed volume is 0.000 + 9.854 + 118 – 18 = 109.854. Dividing the swept volume by the compressed volume we get 10.25:1. Static Versus Dynamic …
