🔍 Key Concepts

• Diesel ignition principle (compression ignition vs. spark ignition) • Effect of compression and temperature on fuel auto-ignition • Whether lube oil pressure or fuel booster pressure directly affects starting

💭 Think About

• Ask yourself: What does a diesel engine absolutely need at the moment of starting for fuel to ignite without a spark plug? • Which of these options would actually prevent the air–fuel mixture in the cylinder from reaching its auto‑ignition temperature? • Which options describe conditions that might be abnormal, but would NOT by themselves stop the engine from firing during cranking?

✅ Before You Answer

• Verify how compression ratio and temperature are related in diesel operation. • Check whether ambient air pressure changes inside a machinery space enough to be a common starting fault. • Confirm if high lube oil or high fuel booster pressure is more likely to be a protection/alarm issue rather than a direct cause of failure to start.
