(d) Bad engine design

I got this question during an interview for a job.

Answer 1

The correct answer is:

(b) Poor control by the governor

Hunting occurs when there is poor control by the governor in regulating the engine speed. It refers to the oscillation or fluctuation in engine speed, where the governor system overcompensates or reacts too slowly to changes in load, leading to an unstable or oscillating performance. Proper governor control is essential for maintaining stable engine speed, especially under varying loads.
