You've heard the term compression ratio before, but have you ever wondered exactly what it means? Well, it's time to explain exactly what compression ratio is, and why every carmaker is now obsessed ...

Ali Solouk received an SAE International best presentation and dean’s outstanding research scholar awards for his research on integrating high efficiency engines with electrified powertrain technology ...

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 compression ratio clarification wasn’t the only one issued by the FIA. For some time now, F1 has used ultrasonic fuel ...

ABSTRACT Future emissions standards for passenger cars require a reduction of NO ₓ (nitrogen oxide) and CO ₂ (carbon dioxide) emissions of Diesel engines. One of the ways to reach this challenge while ...

One of the key variables for an internal combustion engine is its compression ratio. This is the ratio of the maximum volume within the cylinder (when the piston is at bottom dead center) and the ...

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 ...

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 ...

Although car manufacturers are embracing alternative power sources, they haven't given up on internal combustion just yet. Along with a push towards downsized turbo power, some of the smartest ...

SAE Transactions, Vol. 110, Section 3: JOURNAL OF ENGINES (2001), pp. 1234-1252 (19 pages) Using methanol as a fuel, this study examines the chemical-kinetics mechanism responsible for the enhancement ...

If you know much about how engines work, the idea of a variable compression ratio seems almost crazy. The idea isn't new, in fact Saab claims to have been working on it since the 1980s, but it's never ...

Mazda’s new SkyActiv-X engine will go against every convention you thought you understood about gasoline engines. It’s supercharged, but for efficiency purposes, not to increase power. It has a ...
