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 ...

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 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 ...

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 ...

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 ...

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 ...

There’s a new gas engine in town. Most recent vehicle powertrain news relates to electric drive designs. However, gasoline and diesel internal combustion engines still run the vast majority of ...

To meet stricter global emissions standards, carmakers are trying to squeeze every last bit of efficiency out of internal-combustion engines. That has led Infiniti to turn to a technology engineers ...

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 ...

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 ...
