Question 395Motor Plants - Assistant Engineer

The correct answer is B) increasing the speed. In the illustrated auxiliary diesel engine governor, decreasing the distance between piece No. 6 and piece No. 10 will increase the speed of the engine. This is because piece No. 6 is the speed setting device, and reducing the distance between it and piece No. 10, which is the spring, will increase the tension on the spring. This increased spring tension will cause the governor to apply less force to the fuel system, allowing the engine to run at a higher speed. The other answer choices are incorrect because: A) Decreasing the distance would increase the speed, not decrease it. C) Increasing the speed droop setting is not the same as increasing the speed. D) Decreasing the overspeed trip setting is not related to the change in distance between the pieces.
