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

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 ...

It's only teasing a bit of information for now, but it will be properly unveiled during this year's Paris Motor Show. Cars are Andrew's jam, as is strawberry. After spending years as a regular ol' car ...

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 ...

Pretty simple question actually (or so my ignorant mind thinks): At what compression ratio would an engine benefit from higher octane fuel? The Focus I drive is just over 10:1, and I've heard some say ...

A refrigeration system’s compression or pressure ratio is defined as the absolute discharge pressure divided by the absolute suction pressure. Calculating this ratio can be a big help when it comes to ...

Installing a recycle valve in parallel with the antisurge valve of a turbine-driven multistage (low pressure/high pressure) centrifugal compressor, in combination with control system modifications, ...

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