Q

The property of a fuel oil which is a measurement of its available energy, is known as its __________.

🔍 Key Concepts

• Fuel oil properties related to combustion and engine performance • Difference between energy content vs. ignition quality of a fuel • Common fuel specs: cetane number/index, viscosity, heating value

💭 Think About

• Which property directly tells you how much heat (energy) can be obtained from burning a given amount of fuel? • Are cetane number and cetane index more about how easily the fuel ignites or about how much total energy it contains? • Is viscosity related to energy, or to how easily the fuel flows and can be pumped/injected?

✅ Before You Answer

• Identify which term is defined in textbooks as the energy per unit mass or volume of a fuel when burned completely • Confirm that cetane number and cetane index are used mainly for diesel ignition quality, not total energy content • Verify that viscosity index deals with how viscosity changes with temperature, not the fuel’s energy content
