🔍 Key Concepts

• How fuel burns more efficiently when it is broken into very small droplets • The role of fuel injectors and burner nozzles in diesel and boiler systems • Difference between mechanical handling of fuel and preparing fuel for actual combustion

💭 Think About

• Which term specifically refers to turning liquid fuel into a spray or mist for burning, rather than just moving or cleaning it? • Think about what happens right before fuel meets the flame or combustion air—what process prepares it? • Which processes (from the choices) are about separation or movement, and which is about preparing fuel to burn efficiently?

✅ Before You Answer

• Identify which option describes spraying fuel into fine droplets instead of just moving it through the system • Eliminate any choices that only deal with cleaning or transporting fuel • Focus on the term most often used with fuel injectors, burners, and nozzles in diesel engines and boilers
