The injection pump of a diesel engine is driven by which component?

Explanation:
The driving source for the injection pump is the camshaft. Its lobes provide the precise, timed push that advances the pump plunger so fuel is pressurized and injected at the correct crank angle. This synchronization with the valve timing is essential for proper combustion in a diesel engine. The governor’s job is to regulate how much fuel the pump delivers, not to drive the pump itself. The other options aren’t relevant drives: a piston’s motion or a gudgeon pin relate to the engine cylinders, not the pump drive.
