The crux of the matter lies in that the Formula 1 compression ratio is not measured by sensors during engine operation, but statically. The FIA simply compares the ratio in volume in the cylinder ...

Low- And High-Compression Fuel Economy Engines: The Techniques Are About The Same, But The Approach To Each Is Somewhat Different. A.Most stock cylinder heads have factory-cut undercuts of the type ...

Engine compression ratios have become a hot topic ...

F1’s 2026 rules set a 16:1 compression ratio limit for engine cylinders. This caps how much the engine can squeeze fuel before burning it — the more you squeeze, the hotter it gets and the more power ...

2.Reduced engine rpm (without attending losses in net torque) tend to improve overall fuel economy and driveability. 3.Treat multi-cylinder engines as a combination of several single-cylinder engines, ...

A loophole in Formula 1’s new technical regulations offers a way around the 16:1 compression ratio cap, introducing ...

As we face the end of the internal-combustion era, the straight-six has made an unlikely comeback. Well, unlikely might not be the right word for an engine configuration of such fundamental rightness.
