🔍 Key Concepts

• How a diesel engine ignites fuel compared to a gasoline (petrol) engine • Difference between internal vs external combustion engines • What the terms vacuum ignition, compression, and four cycle actually describe

💭 Think About

• Think about what physically causes the fuel–air mixture to burn in a diesel engine. Is it a spark, heat from compression, or something else? • Ask yourself: is "four cycle" a type of ignition, or does it describe how many strokes are in the engine’s operating cycle? • Consider whether "external combustion" matches what happens in an engine where fuel burns inside the cylinder.

✅ Before You Answer

• Identify which option describes an ignition method rather than a full engine cycle or a combustion location. • Confirm that in a diesel engine, the fuel burns inside the cylinder, not in a separate boiler or furnace. • Make sure you can explain in your own words how heat is produced in the cylinder right before the fuel is injected.
