The compression ratio isn’t just a number: it’s one of the greatest determining factors in engine building. Compression ratio determines the type of fuel, how much boost, and has a significant ...

Data compression ratio, also known as compression power, is a computer-science term used to quantify the reduction in data-representation size produced by a data compression algorithm. The data ...

Compression ratio is just the difference between the biggest and smallest volume in a cylinder. Smallest is when the piston’s at the top, biggest is when it’s at the bottom. So if the volume ...

Increasing compression ratio increases flame speed, extending the air-fuel ratio for peak efficiency an additional 0.1 lambda. Increasing combustion variability only affects the downward slope in ...

Anamorphic lenses are very popular right now, so here's a guide to what all those compression ratios mean! It's not really clear why anamorphic lenses originally had a two-to-one compression ratio.

In Two Stroke Spark Ignition engines the thermal efficiency increases with increase in compression ratio. Also, with higher compression ratios the lean burning limit increases because of the reduction ...

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 ...

Engineers have been trying to perfect variable-compression engines for almost as long as engines have existed. So far, though, only Nissan has succeeded in bringing one to production. Its Variable ...
