Question 109Motor Plants - 1st Asst/Chief70% to pass
When changing over from residual to distillate fuel on a slow-speed diesel main engine, what is a good guideline to follow regarding the change over?
AI Explanation
The correct answer is B) Rate of temperature change of fuel to the engine should not exceed 2 degrees C per minute.
This is the correct answer because a sudden change in fuel temperature can cause thermal shock and damage to the engine components. Slowly transitioning the fuel temperature ensures a gradual change that the engine can accommodate without issue. Changing over too quickly, as in option C, can lead to engine problems. Options A and D prescribe arbitrary time limits that may not be appropriate for all engine configurations and loads.
