Description

What is a camshaft?

A camshaft is a relatively basic component – a simple length of rod, or shaft, with shaped lobes positioned along it, these have been christened 'cam lobes'. camshaft, in internal-combustion engines, rotating shaft with attached disks of irregular shape (the cams), which actuate the intake and exhaust valves of the cylinders. The cams and the camshaft are usually formed as a unit, with the cams set at angles so as to open and close the valves in a prescribed sequence as the cams rotate. A separate camshaft for each row of cylinders is driven by gears or chains from the crankshaft.

What kind of material is a camshaft made of?

Camshafts are made of steel and cast iron. The starting material of the steel cams is the rod material, then precisely machined and inductively hardened on the surface, respectively case-hardened. Cast iron shafts are produced by casting an iron alloy.

Which is better cast iron or steel camshafts?

Steel camshafts handle more mechanical loads than cast iron camshafts and are comparable to OE camshafts. Camshafts of hardened cast iron have a harder surface, however, this does not mean that they should necessarily have shorter lifetime.

What is the purpose of a camshaft?

A camshaft is the element of an internal combustion engine the purpose of which is to open and close the valves. Working in conjunction with the crankshaft, the camshaft rotates at half the speed of the crankshaft in a 4-stroke engine cycle and at the same speed in a 2-stroke engine.

Understanding Camshaft Specifications

1. Lift. Lift refers to maximum valve lift.

2. Overlap. Overlap is the angle in crankshaft degrees that both the intake and exhaust valves are open.

3. Advance/Retard. Cam Advance and Retard Advancing or retarding the camshaft moves the engine’s torque band around the RPM scale by moving the valve events further ahead or behind the movement.
