What component sets on the camshaft and spins as the crankshaft rotates to lubricate the engine?

The component that sets on the camshaft and spins as the crankshaft rotates to lubricate the engine is the oil pump. The oil pump is crucial in circulating oil throughout the engine to ensure that all moving parts are properly lubricated, helping to reduce friction and wear, and to maintain optimal engine temperature. The oil pump engages with the crankshaft or camshaft, depending on the design, allowing it to operate when the engine is running.

Understanding the lubrication system is integral to engine performance; it prevents engine components from seizing and helps maintain the integrity of the engine's parts. Options such as control, lubrication system, and crankcase refer to broader concepts or components related to the engine’s operation and configuration, but they do not specifically perform the function of circulating oil in the way that the oil pump does. The oil pump's specific placement and functionality are designed to address the unique lubrication needs of an engine.
