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.

Red Bull's engine chief Ben Hodgkinson has said he is confident the team's 2026 power unit is legal and that the recent ...

We might be covering ground that's well trampled for many, but the static compression ratio of an engine is simple to understand: it's all the volume of a cylinder above the compression ring at Bottom ...

Ahead of F1 winter testing at Barcelona, the FIA will hold a meeting with technical experts, with all eyes on an alleged ...

Max Verstappen was caught out on the much-talked-about advantage Mercedes is believed to have secured by exploiting the 2026 engine compression ratio. Asked by Bloomberg whether Red Bull and Mercedes ...

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 ...

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 ...

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 ...

Infiniti introduced the world's first variable compression-ratio engine, a technology it claims to have been working on for two decades, at the 2017 Los Angeles Auto Show. A variable compression-ratio ...
