A camshaft is a shaft to which a cam is fastened or of which a cam forms an integral part.
An early cam was built into Hellenistic water-driven automata from the 3rd century BC. The camshaft was later described in Turkey (Diyarbakır) by Al-Jazari in 1206. He employed it as part of his automata, water-raising machines, and water clocks such as the castle clock. The cam and camshaft later appeared in European mechanisms from at least the 14th century, or possibly earlier.
In internal combustion engines with pistons, the camshaft is used to operate poppet valves. It then consists of a cylindrical rod running the length of the cylinder bank with a number of oblong lobes protruding from it, one for each valve. The cam lobes force the valves open by pressing on the valve, or on some intermediate mechanism as they rotate.
Camshafts can be made out of several types of material. These include:
Chilled iron castings: Commonly used in high volume production, chilled iron camshafts have a good wear resistance since the chilling process hardens them. Other elements are added to the iron before casting to make the material more suitable for its application.
Ever wonder what those camshaft specification numbers really mean and how they affect engine performance? This episode of Engine Masters presented by AMSOIL is here to help, as David Freiburger explains cam lift, duration, love separation angle, and installed centerline. Next, we test a low-rpm cam and a high-rpm cam in the same engine to demonstrate the power differences. Engine Masters is supported by Mr. Gasket and Earl's Vapor Guard hose.

Song title: Cycles by Jason Shaw - www.audionautix.com This video shows the operation of double overhead camshaft DOHC and the timing difference between normal camshaft and tuned camshaft for higher power output. Please note that the CAM PROFILE shown here is NOT what you find in real world application. The real camshaft profile features ramp angles and profile curves to ease the valve train stresses. The camshafts were modeled after the stock and "fast road" camshafts available for Fiat FIRE normally aspirated petrol engine 1242 cc 16V 80 Bhp 188A5000.
Just a quick explanation on how an engine works and what the camshaft does. Its very simple to understand when you see it spin. Engines are beautiful art in my opinion.
In this episode of Engine Masters presented by AMSOIL, you’ll learn a simple combination for a 600hp big-block Chevy. Many people building engines like this are torn between the streetability of a camshaft that uses hydraulic roller lifters and the race-level rpm capabilities of the solid roller lifters. This video will explain the tech and show you the real-world difference in power between the two styles of camshafts, so you can decide what’s best for your next buildup.
