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 ...

Diesel engines do their hardest work in the toughest jobs, from highway semis to construction equipment, and the reason they can survive that punishment starts with how fiercely they squeeze the air ...

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, ...

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 ...

Engine compression ratios have become a hot topic ...

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.

A political firestorm has been brewing in Formula 1 in recent weeks and months over whether engine manufacturers have found a loophole in the new 2026 technical regulations. Mercedes and Red Bull may ...

Should you go with a naturally aspirated engine or a turbocharged one? Both have pros and cons, but we think one engine type ...

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 ...
