A running engine produces heat, which expands its metal body, thereby increasing its compression ratio. This is true for ...

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 ...

Formula 1’s next-generation power units are not even on the grid yet and they are already reshaping the competitive landscape ...

For the past decade, high-compression engines have been sorely missing from American cars, partially due to the misconceptions that high-compression engines and unleaded fuel were incompatible and ...

We may receive a commission on purchases made from links. While browsing auto repair and maintenance tools at your local parts store, you've likely come across compression testers like the Orion Motor ...

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 ...

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 ...

Despite the turbulence Nissan has faced over the past few years, some of its technology is undeniably impressive. Perhaps the crowning jewel of this engineering power is its variable compression ...

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 ...

Let's discuss something that is well known by diesel mechanics and hard-core enthusiasts but may not be fully understood by new diesel owners or people who may have heard the term "compression ...

A fundamental difference between gasoline and diesel engines is that a gasoline engine uses spark ignition while a diesel engine uses compression ignition. Before we delve deeper, let's understand how ...
