The compression ratio isn’t just a number: it’s one of the greatest determining factors in engine building. Compression ratio determines the type of fuel, how much boost, and has a significant ...

Shown here are the component volumes that comprise the total clearance volume when the piston is at TDC. If the piston is domed or dished, that affects the clearance volume too. To measure both the ...

We might be covering ground that's well trampled for many, but the static compression ratio of an engine is simple to understand: it's all the volume of a cylinder above the compression ring at Bottom ...

The compression ratio in Mercedes’ and Red Bull's 2026 engines has come under scrutiny in F1, but what’s really behind it?
