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

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 ...

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 ...

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 ...

The ability to vary an engine's compression ratio has been a "holy grail" quest of engine engineers for decades, because "one size" of compression ratio cannot possibly fit all the operating ...

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 ...

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 ...

Want to know how healthy or unhealthy your engine really is? Get yourself a compression tester and find out. Despite how complex many modern vehicles are, you can do many common repair and maintenance ...

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