A mechanical fuel pump is actuated by what component?

A mechanical fuel pump is actuated by what component?

• A. Camshaft
• B. DC power
• C. MPU
• D. Crankshaft

Answer: (A)

A mechanical fuel pump is actuated by the camshaft. The function of this component is vital; as the camshaft rotates, it pushes against a lever or arm that then operates the fuel pump. This mechanical action generates the necessary pressure to move the fuel from the tank to the engine. In a typical setup, the camshaft is synchronized with the engine’s operation, ensuring the pump supplies fuel at the right times during the engine cycle. This design is common in older vehicle models where electrical fuel pumps are not utilized. The reliance on mechanical components for actuation means that the fuel delivery occurs without the need for electrical power, which can be advantageous in certain situations.
