🔍 Key Concepts

• Fuel injector opening pressure and how it affects when injection starts in the cycle • Relationship between pump plunger pressure buildup and nozzle opening • What happens to injection timing, quantity, and spray if you increase nozzle opening pressure

💭 Think About

• If the nozzle needs a higher pressure to open, does the injector open earlier or later in the stroke? Think about what has to happen inside the pump first. • How would a higher opening pressure affect the total time the nozzle is actually open during each cycle? Longer, shorter, or the same? • Consider whether a higher opening pressure would tend to cause clean cutoff of fuel, or more dribble, and whether it would sharpen or weaken the spray pattern.

✅ Before You Answer

• Compare injection start timing at normal vs higher opening pressure – does the plunger need more travel to reach the higher pressure? • Think about whether nozzle dribble is usually associated with too high or too low opening pressure and poor seating. • Decide if a higher opening pressure is more likely to change when injection begins or how much fuel actually gets through in the same cam stroke.
