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 ...
Diesel engines are different from gas engines in numerous ways, including their use of high compression ratios. Here's why ...
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 ...
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 ...
It seems like every major automaker these days is using tricks like variable-valve timing - often in conjunction with forced induction - to eke better efficiency out of their engines while still ...
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 ...
Infiniti showed off a slightly updated Q50 yesterday at the Paris Motor Show, but nobody gave a damn because right next to it was this: the first ever production-ready variable compression-ratio ...
Jonathan loves just about anything with a motor and a steering wheel. As a kid, Jonathan collected any kind of toy car he could lay his hands on, and begged his parents to take him to the monster ...
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 ...
The new Infiniti QX50 might not seem the most natural fodder for these pages, but its engine surely is. Just introduced to the world at the Los Angeles Auto Show, the crossover is powered by the world ...
