Question 51Motor Plants - 1st Asst/Chief
70% to passThe component labeled "A" on the engine reversing device shown in the illustration, performs its function by transmitting. Illustration MO-0125
Aa hydraulic pressure which shifts an alternate set of camshaft followers to ride on the engine camshaft
Ban electric voltage which energizes solenoids to de-clutch the engine
Ca fuel oil pressure signal which reverses the engine governor control cylinder
Da pneumatic signal which activates a hydraulic control cylinder allowing the camshaft to shift axially
AI Explanation
The correct answer is D) a pneumatic signal which activates a hydraulic control cylinder allowing the camshaft to shift axially. The component labeled "A" on the engine reversing device is responsible for transmitting a pneumatic signal that activates a hydraulic control cylinder. This allows the camshaft to shift axially, which is the key function of the engine reversing device in order to reverse the direction of the engine. The other answer choices are incorrect because they do not accurately describe the mechanism of the engine reversing device. Options A, B, and C involve different methods of engine control that are not relevant to the specific component and function described in the question.
