Main Functions of a Camshaft:
1. Controls Valve Timing
* Opens and closes the intake and exhaust valves at the correct time during the engine cycle.
2. Regulates Air-Fuel Intake
* Allows the intake valves to open so the engine can draw in the air-fuel mixture.
3. Controls Exhaust Gas Release
* Opens the exhaust valves to let burnt gases leave the combustion chamber.
4. Ensures Engine Efficiency
5. Supports Engine Power Output
* The camshaft’s design influences engine torque, horsepower, and overall performance.
Why Must a Camshaft Be Replaced?
1 Excessive wear
2 Abnormal engine noise (ticking or knocking).
3 Loss of engine power and performance.
4 Misfiring, rough idling, or poor fuel economy.
Note! A damaged camshaft can cause incorrect valve timing, poor engine performance, and in severe cases, major engine damage.
