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 ...

Because diesel vehicles do not use spark plugs, they must rely on higher compression ratios to ignite the diesel fuel without ...

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 ...

As a concept, the internal combustion engine is as old as dirt. To our luck, the ICE is still relevant nowadays thanks to engineering developments such as direct injection, cylinder deactivation, stop ...

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 ...

In a world full of similarly priced compact luxury crossovers, one way to differentiate yourself is with what’s under the hood. That’s the approach Infiniti has taken with the all-new 2019 Infiniti ...

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 ...

Diesel engines do their hardest work in the toughest jobs, from highway semis to construction equipment, and the reason they ...

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 ...

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 ...

We might be covering ground that's well trampled for many, but the static compression ratio of an engine is simple to understand: it's all the volume of a cylinder above the compression ring at Bottom ...

What is one of the most critical variables you can set when building an engine? That could be a long debate, but compression is certainly one of the main ones. It dictates not only how much power you ...
