🔍 Key Concepts

• Difference between combustion knock (fuel/air related) and mechanical knock (moving parts, clearances, wear) in diesel engines • Effect of shutting off fuel to one cylinder on combustion noise vs mechanical noise • Typical causes of ring problems and piston cooling issues, and what symptoms they usually show

💭 Think About

• If the knock continues even after the fuel to that cylinder is secured, is the noise still likely caused by combustion, or by something else? • Which of the listed options would continue to cause a knocking sound whether or not fuel is being injected into that cylinder? • For each choice, ask yourself: would turning off fuel immediately change this condition, or would it stay the same?

✅ Before You Answer

• Verify which problems are directly related to combustion process (injection, burning of fuel) versus purely mechanical issues • Eliminate any options where the symptom would be expected to improve or disappear when fuel is cut off • Focus on the choice that clearly points to a physical fault in the moving components of that cylinder, independent of fuel delivery
