Question 1 of 27070

If a diesel engine driving a generator turns over freely but fails to fire properly, the cause could be __________.

🔍 Key Concepts

• How diesel engines ignite fuel (compression ignition, no spark plugs) • Common causes of a diesel cranking normally but not starting • Effect of fuel delivery problems versus mechanical issues like compression

💭 Think About

• Ask yourself: if the engine is turning over at normal speed, which choices actually prevent fuel from burning? • Which option would most likely introduce a gap or interruption in the steady flow of fuel to the injectors? • Which options would more likely cause hard starting or slower cranking rather than a freely turning engine that simply won’t fire?

✅ Before You Answer

• Identify which choice directly affects fuel flow to the injectors, not just pressure or engine load • Eliminate any answer that would normally make the engine harder to turn, not easier • Focus on the option that can trap compressible gas where there should be liquid fuel in the system
