A gasoline piston engine that can dynamically change its compression ratio —that is, the amount by which the piston squeezes the fuel-air mixture in the cylinder—has long been a holy grail of engine ...

Infiniti has revealed an engine concept this year, and it is of the variable compression kind. While not the first of its type as a concept, this motor might bring a new line of internal combustion ...

While the fashion in high-tech automotive developments might lean towards hybrids and electric vehicles at the moment, there’s still plenty of scope to improve the good old internal combustion engine ...

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 ...

Over the course of a round-table discussion and a separate private interview with Alain Raposo, Alliance global vice-president, powertrain and EV engineering and Shinichi Kiga, chief powertrain ...

Infiniti is destined to become the first major automaker with a variable compression engine. The engine, dubbed the VC-T (Variable Compression-Turbo), has the ability to alter the compression ratio, i ...

Infiniti's new Variable Compression Turbo is the centerpiece of this crossover. Variable compression engine sounds like something you’d hear from a super villain describing his latest contraption. At ...

Forget variable length intakes and variable valve timing, Infiniti is going all the way and introducing variable cylinder compression ratios. The new VC-T turbo engine automatically adjusts between a ...

While significant attention is being paid to battery-electric and hydrogen fuel-cell powertrains, carmakers are still trying to wring more efficiency out of internal-combustion engines. Now, Infiniti ...

When the next-generation Infiniti QX50 crossover arrives next year as a 2019 model, it will be powered by a 2.0-liter turbocharged four-cylinder engine introducing a technology never seen before in a ...

In a conventional piston engine, the compression ratio defines the relationship between the largest and smallest volume of a cylinder - when its piston is at bottom dead centre and top dead centre ...

The ability to vary an engine's compression ratio has been a "holy grail" quest of engine engineers for decades, because "one size" of compression ratio cannot possibly fit all the operating ...
