AI Explanation
The correct answer is A) restore hydraulic pressure in the accumulator after starting. The engine-driven hydraulic pump in an auxiliary diesel engine's hydraulic starting system is responsible for replenishing the pressure in the accumulator after the engine has been started. This ensures that there is sufficient hydraulic pressure available for subsequent starting attempts if needed. The other answer choices are incorrect - B) is for engaging the starter motor, C) is for filling the hydraulic system sump, and D) is for bypassing the hydraulic motor when the engine is running, which is not the purpose of the engine-driven pump in the starting system.
