Question 1 of 27070

The starting air rotates a diesel engine at the proper speed, but the engine fails to start. You should check __________.

🔍 Key Concepts

• Starting air system vs. fuel system in a diesel engine • What conditions are needed for combustion: air, fuel, compression, correct timing • How safety trips (like overspeed trips) can prevent an engine from starting

💭 Think About

• If the engine is turning at normal cranking speed but not firing, which basic element of combustion is most likely missing or blocked? • Which option(s) deal with fuel delivery, which with air supply, and which with safety shutdowns? • In real engine troubleshooting, do engineers usually check only one possible cause, or verify several simple things that could all prevent starting?

✅ Before You Answer

• Identify whether air supply could be restricted even though starting air is rotating the engine • Consider whether fuel lines could trap air and stop fuel injection • Think about whether a tripped overspeed device can also act as a no-start condition, not just an overspeed shutdown

Question 1 of 27070

The starting air rotates a diesel engine at the proper speed, but the engine fails to start. You should check __________.

the over speed trip

for an obstructed air filter

for air-bound fuel lines

all of the above
