The "LS" nomenclature originally came from the Regular Production Option (RPO) code LS1, assigned to the first engine in the Gen III engine series. The LS nickname has since been used to refer generally to all Gen III and IV engines, [14] but that practice can be misleading, since not all engine RPO codes in those generations begin with LS. [15]
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.
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.
