🔍 Key Concepts

• diesel fuel injection system components (cam, plunger, delivery valve, nozzle/needle) • difference between what times the injection vs what physically opens the nozzle • role of fuel pressure vs mechanical linkage at the nozzle tip

💭 Think About

• In a typical diesel system, what creates the high pressure, and what part actually moves to uncover the nozzle orifices? • Does the cam or timing gear usually act directly on the nozzle, or on another component that indirectly causes the nozzle to open? • At the nozzle itself, what force keeps it closed, and what must happen to overcome that force?

✅ Before You Answer

• Identify which option describes a force or condition acting right at the nozzle needle (not elsewhere in the system). • Confirm which components (cam, timing gears) are mainly used for timing and pressurizing rather than directly lifting the nozzle needle. • Recall that most nozzles stay shut by a spring force, and consider what factor must exceed that force for the nozzle to open.
