Porsche Camshaft For Porsche 993 (1995) Models.

A camshaft is a crucial component in an internal combustion engine. It controls the timing of the intake and exhaust valves, which in turn regulate the flow of air and fuel into the engine's cylinders and the expulsion of exhaust gases.

Key Components:

• Lobe: The raised portion of the camshaft that pushes against the valve lifter or rocker arm, causing the valve to open.
• Journal: The cylindrical portion of the camshaft that rotates within the engine block's head.
• Timing Marks: These marks are used to ensure proper alignment of the camshaft with the crankshaft during engine assembly or timing belt replacement.
