When the function of a camshaft(s) is explained to non-mechanically-inclined types, it's sometimes referred to as the "brain" of an engine. Most engines will live their entire lives with the stock cam ...

Sometimes we all need a little change in our lives. The same could be said for that camshaft that pumps the valves open and closed in your street engine. What was once state of the art is now obsolete ...

Performance may always lay heavy odds on power, but you also need the brains to go with it. The four-stroke internal combustion engine has been around for over a century, but we're still learning ...

It's appropriate, we think, that a camshaft has lobes, since this relatively simple device is so often called the brains of an engine. And indeed, a camshaft does direct several engine functions in a ...

The camshaft orchestrates every intake and exhaust event in the engine, and a single worn lobe can kill power to an entire cylinder. Oil starvation during cold starts is responsible for a ...

It's appropriate, we think, that a camshaft has lobes, since this relatively simple device is so often called the brains of an engine. And indeed, a camshaft does direct several engine functions in a ...

The engines of yesteryear were pretty simple, with tappets clackity-clacking away on cam lobes, opening valves, and making a ruckus while doing it. Mechanical lifters were adequate for valve operation ...

Fiat’s 1.4L family of engines utilizes “MultiAir” technology. Dave Schmidt is chief engineer for Chrysler’s North American 1.4L engine program, and here’s how he described MultiAir to this writer, and ...
