🔍 Key Concepts

• Cetane number as a measure of diesel fuel’s ignition quality (how quickly it starts burning after injection) • Relationship between cetane number and ignition lag (ignition delay) • What "**cetane" actually is (a reference hydrocarbon used to define the cetane scale)

💭 Think About

• Think about how a higher cetane number affects engine starting and combustion smoothness. Would ignition delay be longer or shorter? • Consider how octane in gasoline has a scale with reference fuels. Does cetane use a similar idea with a reference hydrocarbon? • Ask yourself whether the cetane scale is defined between two specific numbers and whether real fuels can exceed 100 on that scale.

✅ Before You Answer

• Verify that cetane itself is a real, colorless liquid hydrocarbon used as a reference fuel. • Confirm whether higher cetane number corresponds to longer or shorter ignition lag in diesel engines. • Check if the cetane scale is strictly limited to 0–100 or if fuels (or additives) can be rated above 100 on that scale.
