Performance diesel engines are usually the realm of European automakers, but the highest-revving diesel actually comes from ...

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 ...

As you may know, an engine's compression ratio is directly linked to its combustion efficiency. All else being equal, higher-compression engines tend to make more power while offering better fuel ...

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 ...

A computer generated power stroke of an internal combustion engine, following ignition - Pathompong Thongsan/Getty Images When comparing engine specs for nearly any combustion engine automobile, we ...

Most engines generate power from an internal combustion system. On the basic level, these engines work by compressing fuel and air into a tight space. Within the cylinders of an engine, pistons pump ...

Low- And High-Compression Fuel Economy Engines: The Techniques Are About The Same, But The Approach To Each Is Somewhat Different. A.Most stock cylinder heads have factory-cut undercuts of the type ...

With the turn of the calendar into a new year, there always comes increased anticipation for the new racing season that's to come. As Formula 1 begins the lead-up to its 2026 season, there's already ...

You probably know how diesel engines work, but it's one thing to understand the theory and a whole different thing to actually see how diesel fuel ignites.

Nissan’s variable-compression turbo (VC-Turbo) is a unique engine capable of variable compression adjustment. Unlike traditional engines, which have a fixed compression ratio, the VC-Turbo engine ...
