You might have heard about high compression ratios, but what exactly are they, and what kind of effect do they have on an ...

A gasoline piston engine that can dynamically change its compression ratio —that is, the amount by which the piston squeezes the fuel-air mixture in the cylinder—has long been a holy grail of engine ...

Formula 1 has always been a sport where the rulebook is treated less like a […] ...

Mercedes' rivals succeed in securing a rule change following a pre-season technical row over engine performance.

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 ...

Increasing an engine’s compression ratio is a proven way of unlocking extra horsepower, but there’s a point of diminishing returns. The team at Garage 54, the Russian mechanics who built a V16 using ...

Formula 1 bosses are moving towards a rule change that would close a loophole rivals believe Mercedes have exploited in the ...

In a conventional piston engine, the compression ratio defines the relationship between the largest and smallest volume of a cylinder - when its piston is at bottom dead centre and top dead centre ...

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, ...

Every engine has a specific compression ratio. The air-fuel mixture is compressed in the cylinder to create an ignition, the force of which depends on the compression ratio: the volume of the cylinder ...

At first glance, the concept of engine compression is simple enough:It's the ratio of the volume of the combustion chamber and bore when thepiston is at bottom dead center (BDC) versus when it is at ...
