🔍 Key Concepts

• Ignition quality in diesel versus gasoline engines • What cetane and octane numbers measure • How diesel fuel combustion (compression-ignition) differs from spark-ignition

💭 Think About

• Ask yourself: which of these terms is normally associated with gasoline engines rather than diesel? • Which option is specifically defined as a measure of how quickly and easily diesel fuel auto-ignites under compression? • Which choice sounds like a general description rather than a standard, commonly used industry scale?

✅ Before You Answer

• Identify which term is routinely printed at gasoline pumps versus diesel pumps. • Recall that diesel engines rely on compression ignition (no spark) and need a rating of how readily the fuel ignites from compression alone. • Eliminate any term that mainly refers to volatility (tendency to evaporate) rather than ignition quality.
