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

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

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 ...

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

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

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 ...

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 ...

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 ...

The MCE-5 engine from MCE-5 Development in Lyon, France (www.mce-5.com), varies its compression ratio and uses a combined gear and rod-crank mechanism. Varying compression from 7:1 to 20:1 makes the ...

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

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 ...

As a concept, the internal combustion engine is as old as dirt. To our luck, the ICE is still relevant nowadays thanks to engineering developments such as direct injection, cylinder deactivation, stop ...
