🔍 Key Concepts

• diesel combustion process in an individual cylinder • difference between problems caused by fuel injection/combustion vs mechanical parts like rings and cooling • what it means when a symptom disappears after the fuel is shut off to that cylinder

💭 Think About

• Ask yourself: If the knocking stops when there is no fuel to that cylinder, is the cause more likely related to combustion or to purely mechanical parts moving up and down? • Which of these choices would be directly affected by whether fuel is being injected and burned, and which would continue regardless of fuel flow? • Think about what type of problem typically produces a sharp, metallic knock in a diesel when fuel is injected at the wrong time or burns in the wrong way.

✅ Before You Answer

• Confirm which options are linked to combustion quality or fuel injection timing rather than mechanical wear alone. • Eliminate any options that would cause noise even when the cylinder is not firing (i.e., still moving but not burning fuel). • Focus on the fact that the knocking is persistent while firing and disappears immediately when the fuel is cut off.
