Your engine is simpler than you think and only four things separate it from becoming a good-for-nothing lump of aluminum: fuel, air, spark and compression. Smoke billowing from the back of your hoopty ...

When it comes to V8 engines, there are many examples that spring to mind as powertrains that evoke a certain degree of emotion and respect. In Ford’s case, it, too, has plenty of V8s that have formed ...

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 ...

One of the easiest ways to test an engine's health is by checking its compression. Testing compression isn't something the average muscle car owner would do every year, but it is a useful tool to ...

One of the key variables for an internal combustion engine is its compression ratio. This is the ratio of the maximum volume within the cylinder (when the piston is at bottom dead center) and the ...

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 ...

"There's no replacement for displacement!" This has been the battle cry of big block fans everywhere, and for good reason. A Chevy big block brings the thunder, whether you're roasting tires with a ...

Diesel engines do their hardest work in the toughest jobs, from highway semis to construction equipment, and the reason they can survive that punishment starts with how fiercely they squeeze the air ...

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 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 ...
