CAMS, TIMING & VALVETRAIN

Cams, timing and valvetrain are components in an internal combustion engine that control the opening and closing of the engine’s valves.

Cams are rotating parts that control the opening and closing of the engine’s valves.

Timing refers to the precise synchronization of the opening and closing of the engine’s valves and fuel injection with the movement of the pistons.

The valvetrain consists of all the parts that control the opening and closing of the engine’s valves, including the camshaft, pushrods, rocker arms, lifters, and springs.

Correct cam timing and valvetrain operation are crucial for the engine’s performance, fuel efficiency, and emissions.
