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 ...

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 ...

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 ...

With every passing day the Mule provides opportunities beyond our original expectations. Since the 467ci engine belongs to HPP editor Tom DeMauro, it is at our beck and call. This affords HPP the ...

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 ...

In this video, we explore the compression ratio of your engine, covering its definition and significance, as well as how it ...

Compression in a diesel engine is essential for effective and efficient performance. And when compression is lacking, damage can result. That is why it’s imperative to know whether your engine’s ...

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 ...

As we near the end of the road for internal-combustion engines, manufacturers are spending big money to eke out small gains in fuel economy. The latest miracle is Nissan’s VC-T engine, the first ...

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 ...

On paper, Nissan's variable-compression turbocharged engine should have been pretty awesome. Since it could change its compression ratio on the fly, it promised the power of a bigger engine when you ...
