Diesel engines are different from gas engines in numerous ways, including their use of high compression ratios. Here's why that is and what it means.

A meeting of Formula 1's engine manufacturers failed to reach accord on alternative means of measuring compliance with new ...

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 ...

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

The rumoured compression ratio engine loophole adopted by Red Bull and Mercedes has been dismissed as only a "clever ...

Ross Brawn has weighed in on the much-debated engine compression-ratio 'trick' that has been at the centre of discussion ...

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 ...

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 ...

The debate centres on the mandated reduction in compression ratio from 18:1 to 16:1 for the new power units, and ...

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 ...

Nissan's Infiniti division will present its first Variable Compression-Turbocharged (VC-T) engine at the Paris Motor Show next month. This technology took them more than two decades to perfect, and ...

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 ...
