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

Apart from the very curious, not many people ask why diesel engines, compared to gasoline, run higher compression ratios. The argument is reasonably straightforward and starts with fuel ...

A.Here's a pressure-volume diagram for a combustion engine. Although rough, it is an approximation of the so-called air-standard cycle. '' Point (a) is at atmospheric pressure, after which the air is ...

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

However, not all innovations are equal, and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early ...

Nissan’s variable compression engines have caught the attention of U.S. safety regulators, following multiple reports of alleged engine failure, loss of power, engine knocking, and metal chunks and ...

Stock car racing engines are all about efficiency. That's because all the simple solutions for making power have either been maximized or eliminated by the rule book. You aren't allowed power adders ...

Nissan's innovative variable compression engines were a fascinating innovation when they were first revealed, but the jury is still out on whether or not the combustion technology will stick around. A ...
