Irregular engine speed in a diesel-generator can be caused by _______________.
AI Explanation
The correct answer is D) binding in the fuel control linkage.
Irregular engine speed in a diesel-generator can be caused by binding in the fuel control linkage, which regulates the amount of fuel delivered to the engine. Binding in the linkage can prevent the engine from receiving the proper fuel quantity, leading to fluctuations in engine speed.
The other options are incorrect because:
A) High generator load would cause the engine to work harder, but would not directly cause irregular speed.
B) Low fuel viscosity would affect fuel atomization, but not necessarily lead to irregular speed.
C) High injection pressure would impact engine performance, but not necessarily cause irregular speed on its own.
