Question 1 of 27070

Fuel supplied by each unit injector on a two-stroke/cycle single acting diesel engine is directed into each cylinder at a very high pressure through the __________.

🔍 Key Concepts

• Function of a unit injector in a diesel engine fuel system • What part of the injector actually enters the combustion chamber and shapes the fuel spray • Difference between fuel delivery lines and the final discharge point into the cylinder

💭 Think About

• Which component is physically located inside or right at the cylinder and exposed to combustion pressure and heat? • Which items listed are pathways or control devices, and which is the actual outlet where atomized fuel enters the cylinder? • In a unit injector system, does the high pressure exist mainly in an external line, or is it created right at the injector just before fuel enters the cylinder?

✅ Before You Answer

• Identify which choice is the actual discharge opening into the cylinder, not just a pipe or control fitting. • Eliminate any component whose main job is to return, deflect, or control excess fuel instead of injecting it into the cylinder. • Confirm which part of an injector assembly forms the spray pattern and atomization entering the combustion space.
