Strictly defined, compression ratio is the total volume above the piston at bottom dead center (BDC), divided by the total volume above the piston at top dead center (TDC). First, let's look at the ...

As you may know, an engine's compression ratio is directly linked to its combustion efficiency. All else being equal, higher-compression engines tend to make more power while offering better fuel ...

From June 1, the FIA will impose tougher tests on F1 power units in an attempt to clamp down on the compression ratio saga, but what tolerances will be permitted under the new tests?

Didn't expect you'd be looking up articles online about engine compression a few months ago, did you? That's what new F1 regulations can do to you. Luckily, we're here to help. Before we dive into the ...
