The cam can be seen as a device that converts rotational motion to reciprocating (or sometimes oscillating) motion. [clarification needed] [3] A common example is the camshaft of an automobile, which takes the rotary motion of the engine and converts it into the reciprocating motion necessary to operate the intake and exhaust valves of the cylinders.
A camshaft operating two valves. A camshaft is a shaft that contains a row of pointed cams in order to convert rotational motion to reciprocating motion.Camshafts are used in piston engines (to operate the intake and exhaust valves), [1] [2] mechanically controlled ignition systems and early electric motor speed controllers.
In mechanical engineering, a kinematic diagram or kinematic scheme (also called a joint map or skeleton diagram) illustrates the connectivity of links and joints of a mechanism or machine rather than the dimensions or shape of the parts. Often links are presented as geometric objects, such as lines, triangles or squares, that support schematic ...
The cam's shape determines the piston's stroke length, timing, and speed. These factors directly influence the engine's performance characteristics. In a cam engine, the cam is connected to a drive mechanism, usually a shaft. This shaft rotates the cam at a specific speed. The rotation of the cam is synchronized with the engine's combustion cycle.
A cam and follower mechanism uses the shape of the cam to guide the movement of the follower by direct contact. Kinematic synthesis of a cam and follower mechanism consists of finding the shape of the cam that guides a particular follower through the required movement.

A double dwell cam mechanism has a motion function which follows a rise-dwell-fall-dwell motion function sequence that repeats.. Unlike the single dwell, the rise function position ends with the follower's acceleration becoming zero, as it is stationary in the first dwell.
Police in Florida have released body-camera footage showing a Hooters waitress allegedly attempting to flirt her way out of being arrested on suspicion of DUI. Sophia Ross, 22, was pulled over by ...
The original design of the cam-in-head engine was done by General Motors in Detroit, Michigan. [1] Although the camshaft is in the cylinder head, the CIH is not a true overhead camshaft design. Rather it can be thought of as a cam-in-block engine with a greatly shortened valve drivetrain. The camshaft is driven by a roller chain.
