Every car engine has quite a few details, ranging from cylinder count to compression ratios. How does changing the compression ratio affect the engine?

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 ...

From June 1, the FIA will impose tougher tests on F1 power units in an attempt to clamp down on the compression ratio saga, ...

At first glance, the concept of engine compression is simple enough:It's the ratio of the volume of the combustion chamber and bore when thepiston is at bottom dead center (BDC) versus when it is at ...

Mercedes' rivals succeed in securing a rule change following a pre-season technical row over engine performance.

You might have heard about high compression ratios, but what exactly are they, and what kind of effect do they have on an engine's fuel efficiency?

Ferrari team principal Frederic Vasseur does not expect the new compression ratio regulation set to come into force at the start of the summer to be a 'game changer'. A few weeks ago, the FIA moved to ...

Formula 1 teams are testing in Bahrain this week, but a storm is brewing in the background that might turn the season on its head. A rule change could be introduced to rein in the Mercedes power units ...

Formula 1's governing body, the FIA, has announced a resolution to the sport's regulatory row over engine compression ratios, with a tweak to the regulations set for June 1 and a further change in ...

Compression: An automotive term used by everybody, forever. Let's get into some detail and maybe develop a better understanding. Pressure, and more pressure: It's a must-have to produce power within ...

Low- And High-Compression Fuel Economy Engines: The Techniques Are About The Same, But The Approach To Each Is Somewhat Different. A.Most stock cylinder heads have factory-cut undercuts of the type ...

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 ...
