Question 144Motor Plants - 1st Asst/Chief70% to pass
Faulty operation of diesel engine fuel injection nozzles can be a direct cause of _______________.
AI Explanation
The correct answer is B) sediment in the fuel supply.
Faulty operation of diesel engine fuel injection nozzles can lead to sediment buildup in the fuel supply. This is because the improper atomization of the fuel (answer C) caused by worn or damaged fuel injection nozzles can allow unburnt fuel and other contaminants to accumulate in the fuel system. This sediment can then clog the fuel lines and injectors, further exacerbating the issue.
The other answer choices are incorrect because they do not directly result from faulty fuel injection nozzle operation. Excessive fuel nozzle holder cooling (answer A) and distortion of the fuel spray pattern (answer D) may be symptoms of the problem, but they do not cause the underlying issue of sediment buildup in the fuel supply.
