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 ...

"Too little compression will usually result in unmet performance expectations. On the high side [too much compression] carries greater risk in tuning and potential component failure if appropriately ...

Apart from the very curious, not many people ask why diesel engines, compared to gasoline, run higher compression ratios. The argument is reasonably straightforward and starts with fuel ...

The same solution for very different reasons.

We all know the age-old maxim, "There's no replacement for displacement." It's the truth. That's why so many sanctioning bodies use displacement and compression rules to limit engine power. Of course, ...

Formula 1's governing body the FIA says the series' power unit manufacturers have unanimously approved changes to how engine compression ratios are measured, with revisions coming as early as 1 June.

A hot-temperature compression ratio test is one solution set to be tabled at an upcoming meeting of the power unit advisory committee. The matter of compression ratio measurements in the new F1 2026 ...
