🔍 Key Concepts

• Diesel ignition quality and how it affects cold starting • Difference between heating value and how easily fuel ignites • What factors are properties of the fuel itself versus parts of the engine (like injectors)

💭 Think About

• When an engine is cold, which property of the fuel most directly affects whether it will ignite when compressed? • Do high heating value and low carbon residue help with long-term efficiency or with the moment of starting from cold? • Which options are properties that are primarily about combustion cleanliness or efficiency, rather than the ability to start a cold engine?

✅ Before You Answer

• Identify which choice refers to how readily the fuel self-ignites under compression • Eliminate any choices that mostly affect engine wear or deposits rather than starting • Check whether internal flow resistance in the injectors is a fuel property or a mechanical condition
