Question 1 of 27070

If an auxiliary diesel engine frequently stalls, the trouble may be caused by __________.

🔍 Key Concepts

• diesel fuel system operation (how fuel gets from tank to injectors) • effect of air in fuel lines on engine performance • difference between combustion problems and mechanical/assembly issues

💭 Think About

• Which choice would most directly interrupt or reduce the fuel actually reaching the cylinders during normal running? • Which options would be more likely to affect power/efficiency or cause smoke, rather than repeated stalling? • Think about what happens if a diesel runs fine briefly, then dies, then starts again—what kind of problem does that usually indicate?

✅ Before You Answer

• Identify which choice directly affects continuous fuel delivery. • Eliminate options that mainly affect exhaust flow or engine sealing rather than basic running. • Ask whether each condition would cause the engine to lose fuel, lose compression, or change timing, and which of those most commonly causes repeated stalling.
