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 ...

HOW TO CALCULATE COMPRESSION RATIO Compression ratio is a fixed relationship of cylinder volume with the piston at bottom dead center (BDC) divided by cylinder volume with the piston at top dead ...

How do you calculate a compression ratio, and what’s the ideal number for your build? Let’s find out.

Now that we know how to calculate a compression ratio, let’s dig a bit deeper into what compression ratio physically means when applied to a cooling system. In reciprocating compressors, there must be ...

You’ve heard the term compression ratio before, but have you ever wondered exactly what it means? Well, it’s time to explain exactly what compression ratio is, and why every carmaker is now ...

Lower compression ratios can be safer, because there is less chance for detonation, but they lack cylinder pressure and make less power as a result.
