What is one of the most critical variables you can set when building an engine? That could be a long debate, but compression is certainly one of the main ones. It dictates not only how much power you ...

GM has filed a patent application for so-called “Multilink Cranktrains with Combined Eccentric Shaft and Camshaft Drive System for Internal Combustion Engines.” The system is designed to provide ...

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 ...

As a concept, the internal combustion engine is as old as dirt. To our luck, the ICE is still relevant nowadays thanks to engineering developments such as direct injection, cylinder deactivation, stop ...

Formula 1’s next-generation power units are not even on the grid yet and they are already reshaping the competitive landscape. At the heart of the storm is a seemingly dry technical detail, the ...

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 ...

Now that Porsche is going deeper than ever into the world of turbocharged engines, the German automaker plans to rewrite the rules a little bit. The German engineers are currently on a quest for what ...

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 ...
