For more than a century now, automotive engineers have struggled with an unavoidable balancing act when it comes to engine compression. Now, thanks to an innovation from Infiniti, they may get to ...

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 ...

While we like to think of 2002 as being part of a high-tech age, our beloved internal combustion engine hasn't really changed much in the last 50 years. We're still using pushrods and overhead valves, ...

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 ...

If you know much about how engines work, the idea of a variable compression ratio seems almost crazy. The idea isn't new, in fact Saab claims to have been working on it since the 1980s, but it's never ...

Formula 1’s next-generation power units are not even on the grid yet and they are already reshaping the competitive landscape. At the heart of the storm is a seemingly dry technical detail, the ...

Formula 1 has always been a sport where the rulebook is treated less like a […] ...

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 ...

Swiss marine power company WinGD and marine engine manufacturer Hanwha Engine have produced the world's first X72DF-2.2 VCR engine equipped with Variable Compression Ratio technology. This ...

As we near the end of the road for internal-combustion engines, manufacturers are spending big money to eke out small gains in fuel economy. The latest miracle is Nissan’s VC-T engine, the first ...

Infiniti's newest engine is an engineering marvel. The VC-T engine (for "variable compression, turbocharged") can adjust its compression ratio between 8:1 and 14:1 on the fly, offering ...
