Every car engine has quite a few details, ranging from cylinder count to compression ratios. How does changing the compression ratio affect the engine?

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 ...

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 ...

Ever since the first internal combustion engine hit top dead centre, engineers have been locked in an inexorable battle with compression ratios. Too low a compression ratio and the engine's efficiency ...

Additive manufacturing has enabled targeted thermal expansion to boost effective compression beyond the limit set for the 2026 season.

From June 1, the FIA will impose tougher tests on F1 power units in an attempt to clamp down on the compression ratio saga, ...

Formula 1's governing body, the FIA, has announced a resolution to the sport's regulatory row over engine compression ratios, with a tweak to the regulations set for June 1 and a further change in ...

Does “the world’s first production-ready variable compression ratio engine” mean anything to you? For general automotive consumers, perhaps not a thing – at least, not yet. But that’s the big selling ...
