Question 12Motor Plants - Assistant Engineer

The correct answer is C) Ideally the engine should be operated in area "A"; however, it is permissible to intermittently operate the engine in area "B". This is the correct answer because the diagram likely represents the safe operating range for the engine, where area "A" is the ideal operating zone, and area "B" is a permissible but less desirable zone for intermittent operation. Operating the engine within area "A" ensures the engine runs at optimal efficiency and avoids potential damage. While area "B" may be used, it should be done only briefly, as prolonged operation in that zone could lead to maintenance issues. The other options are incorrect because A) allows operation in any area without proper load management, B) permits extended operation in the less ideal area "B", and D) assumes a specific engine condition without considering the overall operating range.
