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 ...

However, not all innovations are equal, and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early ...

Nissan may have one eye on the future with its extensive electric, autonomous and fuel-cell programs, but the carmaker hasn’t given up on the internal combustion engine just yet. A new ‘VC-T’ ...

Nissan's Infiniti division will present its first Variable Compression-Turbocharged (VC-T) engine at the Paris Motor Show next month. This technology took them more than two decades to perfect, and ...

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 ...

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 ...

One of the key variables for an internal combustion engine is its compression ratio. This is the ratio of the maximum volume within the cylinder (when the piston is at bottom dead center) and the ...

Does “the world’s first production-ready variable compression ratio engine” mean anything to you? For general automotive consumers, perhaps not a thing – at least, not yet. But that’s the big selling ...

On paper, Nissan's variable-compression turbocharged engine should have been pretty awesome. Since it could change its compression ratio on the fly, it promised the power of a bigger engine when you ...
