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

A.Here's a pressure-volume diagram for a combustion engine. Although rough, it is an approximation of the so-called air-standard cycle. '' Point (a) is at atmospheric pressure, after which the air is ...

There’s a new gas engine in town. Most recent vehicle powertrain news relates to electric drive designs. However, gasoline and diesel internal combustion engines still run the vast majority of ...

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 ...

With the combustion chamber being the root of all horsepower, it only makes sense that you start spec'ing an engine build there. One of the key variables in engine building is compression ratio, or ...

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

While the fashion in high-tech automotive developments might lean towards hybrids and electric vehicles at the moment, there’s still plenty of scope to improve the good old internal combustion engine ...

To meet stricter global emissions standards, carmakers are trying to squeeze every last bit of efficiency out of internal-combustion engines. That has led Infiniti to turn to a technology engineers ...

Infiniti introduced the world's first variable compression-ratio engine, a technology it claims to have been working on for two decades, at the 2017 Los Angeles Auto Show. A variable compression-ratio ...

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