The biggest controversy of the winter break, at least for now, has been settled. A solution developed by Mercedes to increase ...

A clever compression ratio trick in Formula 1's 2026 power units is the topic of discussion between teams and the FIA on ...

The compression ratio isn't just a number: it's one of the greatest determining factors in engine building. Compression ratio determines the type of fuel, how much boost, and has a significant ...

Rivals of Mercedes and Red Bull insist they would be breaking the rules if they were to exploit a loophole in the new engine ...

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 ...

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 ...

Forget variable length intakes and variable valve timing, Infiniti is going all the way and introducing variable cylinder compression ratios. The new VC-T turbo engine automatically adjusts between a ...

One of the key variables for an internal combustion engine is its compression ratio. This is the ratio of the maximum volume within the cylinder (when the piston is at bottom dead center) and the ...

While the fashion in high-tech automotive developments might lean towards hybrids and electric vehicles at the moment, there’s still plenty of scope to improve the good old internal combustion engine ...
