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 ...

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 ...

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 ...

Increasing an engine’s compression ratio is a proven way of unlocking extra horsepower, but there’s a point of diminishing returns. The team at Garage 54, the Russian mechanics who built a V16 using ...

Compression: An automotive term used by everybody, forever. Let's get into some detail and maybe develop a better understanding. Pressure, and more pressure: It's a must-have to produce power within ...

For more than a century now, automotive engineers have struggled with an unavoidable balancing act when it comes to engine compression. Now, thanks to an innovation from Infiniti, they may get to ...

Low- And High-Compression Fuel Economy Engines: The Techniques Are About The Same, But The Approach To Each Is Somewhat Different. A.Most stock cylinder heads have factory-cut undercuts of the type ...

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 ...

Diesel engines are different from gas engines in numerous ways, including their use of high compression ratios. Here's why ...
