Red Bull Powertrains' Ben Hodgkinson is confident of having a fully legal engine in 2026, amidst speculation regarding compression

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.

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 Dead Center (BDC) when compared to the volume above the ...

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 influence on an engine’s power and torque potential.

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 design. It looks like Nissan is the Indiana Jones of ...

Ahead of F1 winter testing at Barcelona, the FIA will hold a meeting with technical experts, with all eyes on an alleged engine loophole used by Mercedes and Red Bull

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 minimum volume within the cylinder (when the piston is at ...

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 high-powered 8:1 and a hugely efficient 14:1 ratio as ...

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 engine is a feat of automotive engineering, flummoxing ...
