This overlooked engine part controls everything, and most drivers never think about it.

One of the most satisfying aspects of engine building is selecting the parts that go into the build, and coming up with a combination that is right on target for the intended application. When that ...

This diagram shows the major cam events through one full cylinder cycle (two crank revolutions or 720 degrees), beginning at TDC firing. The exhaust lobe and valvetrain is closer to the front, and ...

In the early days of high- performance engine building, hot rodders discovered that when they squeezed the intake and the exhaust lobes closer together, the engine responded with more power. That ...

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 ...

The camshaft is essential to an engine's operation and efficiency in the intricate world of automobile engineering. Engine enthusiasts and professionals often ask, "What is a camshaft ?". This ...

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 ...

Volkswagen's troubles continue, but this time it's not emissions-related cheating, it's failing camshaft lobes which can wreak havoc on braking performance. Volkswagen is recalling 91,867 cars ...

Mechanical lifters were once commonplace in internal combustions engines, but they've been mostly replaced by hydraulic lifters, which offer a lot of benefits.
