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 ...

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 ...

You’re not going to notice much difference here. It’s still a traditional four-stroke, internal combustion engine, after all. Just when you think we’re approaching a point where we can’t improve on a ...

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 ...

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 ...

An interesting patent has been filed by Toyota for an engine with variable compression. The patent is for an engine with variable length connecting rods. The connecting rod features two hydraulic ...

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 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 ...

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 ...

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 ...

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 ...

You know what variable valve timing is. You're quite familiar with Honda's VTEC system. Now Infiniti has something new for you dive into, and it's all about changing an engine's compression ratio. The ...
