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 ...

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 ...

Nissan engineers have reportedly been working on the engine concept for more than 20 years, and the company claims to have filed more than 300 patents protecting the design and associated technologies ...

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 ...

It seems like every major automaker these days is using tricks like variable-valve timing - often in conjunction with forced induction - to eke better efficiency out of their engines while still ...

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 ...

Honda might be looking back to early aeronautics in its latest bid to make variable compression engines simpler and sturdier. The engine is designed to take advantage of the simple crank design of ...

Last year, Infiniti announced plans to build a Variable Compression Turbo engine, the first of its kind in a production vehicle. Parent company Nissan says it’s been in development for 20 years and it ...

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 ...

Turbocharging has mostly not lived up to its billing of being the savior of internal-combustion engine technology. Earlier this decade, facing increasing fuel economy requirements, automakers rushed ...

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