🔍 Key Concepts

• function of a fuel injection nozzle in a diesel engine • how temperature of the nozzle tip affects fuel atomization and spray pattern • differences between problems caused by rack setting / firing pressure versus those caused right at the nozzle

💭 Think About

• Which option acts directly at the nozzle tip and can physically change how the fuel breaks up into droplets as it leaves the orifices? • Which options mainly change how much fuel is injected or overall engine power rather than the shape and fineness of the spray? • Think about what happens to fuel viscosity and atomization if the nozzle becomes too cold compared to normal operating temperature.

✅ Before You Answer

• Identify which choice relates to nozzle temperature and fuel atomization specifically, not general engine power or timing. • Separate causes that affect quantity/pressure of injected fuel from those that affect spray quality and pattern right at the nozzle holes. • Confirm which factor would most likely lead to poor atomization, larger droplets, or a distorted spray cone coming directly out of the nozzle.
