Nissan brought the first, and only, variable-compression engine to market. But its future doesn't look bright. Complexity in cars is a funny thing. It’s tempting to say that it’s all bad, that more is ...

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 ...

Putting into production an engine with a variable-compression ratio has been an elusive goal since the first patent for one was filed in 1928. Now, after nearly 100 years of failed experiments and ...

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’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 ...

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 ...

GM has filed a patent application for so-called “Multilink Cranktrains with Combined Eccentric Shaft and Camshaft Drive System for Internal Combustion Engines.” The system is designed to provide ...

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 ...

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 ...
