General Motors has just been granted a patent by the United States Patent and Trademark office for a two stage turbo setup with variable geometry in an internal ...

Turbochargers are one of the best methods for extracting more power out of an engine with less total displacement. Unlike a supercharger, which compresses air at the intake stage and runs off a belt ...

Your intake manifold. It takes in air and sends it to your engine's combustion chamber. This is basically the start of the combustion process. After all, you can't have combustion without air.

Engine science isn’t quite a lost art, but it’s something that is much more understood than it used to be. Now, engines are incredibly talented at everything thanks to innovations in combustion ...

The length of an intake runner has a pretty significant effect on the way an engine delivers power. In simple terms, longer runners help generate better low-end torque, short runners provide high-rpm ...

While variable geometry engine air intakes were banned from Formula 1 in 2006, only to become legal again later on, you can find this technology in many road cars today. Typically, it goes by the term ...

Form and Function - A Look at Intake Manifold Design: Intake manifolds play a huge part of power production, here’s some of the hows and whys Internal combustion engines are fairly simply machines.

Something I've been kicking around for a while, and wanted to get opinions on: Is there a reason we can't use variable intake valve timing to "optimize" engine operation for E85 operation, while still ...

Internal combustion engines are fairly simply machines. When you break it down, they are nothing more than air pumps. When it comes to making horsepower and torque, the simple fact is the more air you ...
