Engine Camshaft
Item Name Code (INC) 60172
 |
A shaft with eccentric lobe(s) specifically designed to raise at a predetermined time, the engine poppet valve(s) from the valve seat(s) of an internal combustion engine. It may include facilities for operating accessories, such as fuel pumps, ignition distributors, oil pumps, and the like. Excludes SHAFT (as modified).
Additional Information for Engine Camshaft
An engine camshaft is a crucial component of an internal combustion engine. It is a cylindrical shaft with a series of lobes or cams that are strategically placed along its length. The camshaft is responsible for controlling the opening and closing of the engine's intake and exhaust valves.
The lobes on the camshaft are designed to push against the valve lifters or followers, which in turn open and close the valves. The shape and size of the lobes determine the timing and duration of the valve opening and closing events, which directly affects the engine's performance.
The camshaft is driven by the engine's crankshaft through a timing belt or chain. As the crankshaft rotates, it transfers rotational motion to the camshaft, causing the lobes to actuate the valves according to the engine's specific timing and firing order.
In addition to controlling valve timing, some camshafts also have variable valve timing (VVT) mechanisms. These mechanisms allow for the adjustment of valve timing to optimize engine performance at different engine speeds and loads.
Overall, the camshaft plays a critical role in the proper functioning of an engine by ensuring the precise timing and synchronization of the intake and exhaust valves.
