Question 235Motor Plants - 1st Asst/Chief
70% to passA large change in ambient temperature, or using an oil of a viscosity different than the one recommended by the manufacturer in a mechanical hydraulic governor, will result in the need to adjust the _______________.
Aaccumulator spring tension
Bcompensating needle valve
Cpilot valve opening
Dcompensating spring tension
AI Explanation
The correct answer is B) compensating needle valve. The compensating needle valve is responsible for adjusting the flow of hydraulic fluid in a mechanical hydraulic governor to compensate for changes in ambient temperature or oil viscosity. A change in these factors can affect the governor's ability to maintain the desired engine speed, so the compensating needle valve needs to be adjusted to restore proper operation. The other options are incorrect because they do not directly address the issue of compensating for changes in temperature or oil viscosity. The accumulator spring tension, pilot valve opening, and compensating spring tension are not the primary components that need adjustment in this scenario.
