The purpose of your engine is to compress fuel and air and then ignite it, creating heat energy that then makes mechanical motion. If your engine can't compress the air and fuel properly, the engine ...

For more than a century now, automotive engineers have struggled with an unavoidable balancing act when it comes to engine compression. Now, thanks to an innovation from Infiniti, they may get to ...

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 ...

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 ...

Increasing an engine’s compression ratio is a proven way of unlocking extra horsepower, but there’s a point of diminishing returns. The team at Garage 54, the Russian mechanics who built a V16 using ...

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 ...

Most pickup trucks sold today have internal combustion engines. Passenger vehicles are powered by two main types of engines: compression, aka diesel, and spark ignition, aka gasoline. Besides the type ...

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 ...

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 ...

Any certified gearhead knows that diesel engines do not use spark plugs. But why not? If power in an engine is created by combustion or explosion of flammable liquids, won't a spark plug in a diesel ...
