What is a camshaft, and what does it do

The camshaft's job is to open and close the valves on top of each engine cylinder. Each cylinder is equipped with at least two valves, one of which sucks in fuel and combustible air mixture that, when lit, drives the piston downward in the cylinder. The other valve opens to let the exhaust gases from that combustion escape when the piston rises in the cylinder. The camshaft is a metal rail that rests above the cylinders at the top of the engine. It is constructed of iron or steel. 

Here you can see about a camshaft and what it does do:

Uses of camshaft

The camshaft is used to open poppet valves in internal combustion engines with pistons. Each valve is represented by an oblong lobe that protrudes from a cylindrical rod that runs the length of the cylinder bank. As they rotate, the cam lobes apply pressure to the valve or some other intermediate mechanism to force it open.

Purpose of camshaft

An intake and exhaust valve's opening and closing, as well as the valve overlap that takes place at the top dead center on the exhaust stroke, are all regulated by the camshaft, which also serves as a timing device. The shaft is made up of several journals that move on engine bearings. The valve train is actuated by its egg-shaped lobes, which can either push directly on the valve stems or move lifters and pushrods to move the valve train.

The camshaft is connected to the crankshaft by a timing chain, timing belt, or gears. The problems with the camshaft drive can cause the valves to come into contact with the piston crowns and seriously harm the engine's internal parts.

Additional functions of a camshaft

The oil pump and distributor may be driven by gears machined into older engines' camshafts. In more recent engines, the camshaft may have a position sensor mounted on the end that transmits data to the power train control module to assist it in timing the ignition and fuel injection pulses. Some engines, particularly those constructed in a V configuration and some overhead cam engines, may have multiple camshafts.

Instead of the conventional push-open cam with valve springs, pull the valve shut as the cam rotates past the lobe and back onto the base circle. Engines with desmodromic valve trains use at least two cams, one of which is a pull-close cam and the other of which is a push-open cam.

Understanding how the crankshaft and camshaft relate to one another is crucial. Because the valves control the intake and exhaust gases for the air or fuel mixture, they must be opened and closed at the proper times during the piston's stroke.
