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 ...

Formula 1’s next-generation power units are not even on the grid yet and they are already reshaping the competitive landscape ...

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 ...

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 ...

Ferrari complains as Mercedes and Red Bull exploit a compression ratio loophole in 2026 F1 engines, risking a big early-season advantage ...

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 ...

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 ...

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 ...

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 ...
