Final answer:
The correct answer is d. engine, as the oil pump in a vehicle provides more oil than the engine itself needs, ensuring adequate lubrication of all internal components.
Step-by-step explanation:
The question is effectively asking which component of an engine would not normally require the amount of oil that a commonly designed pump is capable of delivering. "A normal pump is capable of delivering more oil than a needs" is d. engine. This is because the other options listed (a. rotor lobes, b. chamber crankshaft, c.
cylinder block) are all internal components of an engine which require lubrication, but not to the extent that they would surpass the engine's overall oil requirement. The oil pump in a vehicle is designed to provide sufficient oil to lubricate the entire engine, which includes all moving parts like the rotor lobes, crankshaft, and cylinder block.
Therefore, mentioning the correct option, it is clear that a normal pump is capable of delivering more oil than an engine generally needs. This is important for maintaining proper lubrication without causing excessive oil pressure that might lead to seal failure or other issues within the engine.
