Diesel engines are different from gas engines in numerous ways, including their use of high compression ratios. Here's why ...

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 ...

Increasing an engine’s compression ratio is a proven way of unlocking extra horsepower, but there’s a point of diminishing returns. The team at Garage 54, the Russian mechanics who built a V16 using ...

Assuming a properly tuned engine, there are three factors that contribute to poor streetability: long cam duration, high compression ratios, and excessive cruise rpm. Since cam selection is largely ...

"Too little compression will usually result in unmet performance expectations. On the high side [too much compression] carries greater risk in tuning and potential component failure if appropriately ...

Nissan’s variable-compression turbo (VC-Turbo) is a unique engine capable of variable compression adjustment. Unlike traditional engines, which have a fixed compression ratio, the VC-Turbo engine ...

Formula 1’s next-generation power units are not even on the grid yet and they are already reshaping the competitive landscape ...

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 ...

The compression ratio in Mercedes’ and Red Bull's 2026 engines has come under scrutiny in F1, but what’s really behind it?

The compression ratio clarification wasn’t the only one issued by the FIA. For some time now, F1 has used ultrasonic fuel ...

Despite the turbulence Nissan has faced over the past few years, some of its technology is undeniably impressive. Perhaps the crowning jewel of this engineering power is its variable compression ...
