1. Core Structure:
The camshaft, typically made of high-strength alloy steel, rotates within the engine block. It is strategically positioned, usually above the crankshaft, with lobes protruding along its length.
2. Lobes:
The key elements are the lobes, which determine the timing and duration of valve opening and closing. Camshaft lobes are meticulously designed with specific profiles, each tailored to the engine’s requirements.
3. Journals and Bearings:
The camshaft rests on journals, supported by bearings that reduce friction during rotation. Proper lubrication is vital for longevity and smooth operation.
4. Timing Gear:
Connected to the crankshaft by a timing chain or belt, the timing gear synchronizes the rotational movement of the camshaft with the engine’s cycle.
