Cfill the sump and prevent low level in the system
Dbypass the hydraulic motor when the engine is running
AI Explanation
The correct answer is A) restore hydraulic pressure in the accumulator after starting. In an auxiliary diesel engine hydraulic starting system, the engine-driven hydraulic pump is responsible for maintaining the necessary pressure in the hydraulic accumulator. After the engine is started using the stored hydraulic pressure, the pump replenishes the accumulator to ensure there is enough pressure available for the next engine start. The other answer choices do not accurately describe the primary purpose of the engine-driven hydraulic pump in this type of starting system.
