Question 1 of 27070

A defective injector nozzle in a propulsion diesel engine can cause __________.

🔍 Key Concepts

• Combustion process in diesel engines and what happens when fuel is not properly atomized • Effects of over-fueling or poor spray pattern on power, smoke, and exhaust temperature • How a single fault (bad injector nozzle) can produce multiple symptoms at once

💭 Think About

• If fuel is not finely atomized and evenly distributed, what happens to the completeness of combustion inside the cylinder? • How would incomplete or poor combustion show up on: (1) engine power output, (2) visible exhaust, and (3) exhaust temperature readings? • Can a single defective injector nozzle realistically affect only one of the listed symptoms, or is it likely to affect several of them at the same time?

✅ Before You Answer

• For each choice, ask: Could a bad injector nozzle reasonably cause this effect? Don’t think "usually"—think "is it possible and plausible". • Consider that poor atomization can cause both unburned fuel (smoke) and hot spots (high exhaust temp)—verify both possibilities in your diesel engine theory. • Before picking an answer, double‑check whether the question is asking for one specific symptom or all plausible consequences of a defective injector nozzle.
