Question 178Motor Plants - Assistant Engineer

The correct answer is A) Axial piston. In a diesel engine hydraulic starting system, an axial piston starter motor is typically used. This type of starter motor is well-suited for the high torque requirements of starting a diesel engine. The axial piston design allows the starter to efficiently convert the hydraulic pressure into the rotational force needed to crank the engine. The other options are not commonly used in diesel engine hydraulic starting systems. Centrifugal starters are more common in gasoline engines, precision gear starters are used in some electrical starting systems, and turbine drive starters are less common for marine diesel applications.
