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

IRVINE, Calif.—Despite rumors to the contrary, the internal combustion engine is far from dead. Recently we’ve seen several technological advances that will significantly boost the efficiency of ...

Infiniti has revealed an engine concept this year, and it is of the variable compression kind. While not the first of its type as a concept, this motor might bring a new line of internal combustion ...

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 ...

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 ...

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 ...

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 ...

Turbocharging has mostly not lived up to its billing of being the savior of internal-combustion engine technology. Earlier this decade, facing increasing fuel economy requirements, automakers rushed ...

October 3, 2005 It has been a sudden realisation - the world is running out of oil and the laws of supply and demand are set to make petrol prohibitively expensive in the very near future. Sonex ...

While significant attention is being paid to battery-electric and hydrogen fuel-cell powertrains, carmakers are still trying to wring more efficiency out of internal-combustion engines. Now, Infiniti ...

Diesel engines are different from gas engines in numerous ways, including their use of high compression ratios. Here's why ...
