🔍 Key Concepts

• Cetane number as a diesel fuel rating • Difference between gasoline octane rating and diesel cetane rating • What good ignition behavior means inside a diesel engine cylinder

💭 Think About

• Think about what property of diesel fuel matters most at the moment fuel is injected into hot, compressed air. • Ask yourself: does cetane number describe how hard it is to knock, or how easily the fuel starts burning? • Which choice relates directly to how quickly and smoothly combustion begins after injection in a diesel engine?

✅ Before You Answer

• Identify which options are more commonly associated with gasoline (spark-ignition) engines rather than diesel engines. • Focus on the option that best matches how readily fuel starts to burn after it is injected into the cylinder. • Eliminate any choices that describe long-term flow properties (like thickness) instead of combustion start behavior.
