Q

Which of the following conditions may contribute to the formation of deposits on the blades of the turbocharger turbine?

🔍 Key Concepts

• Turbocharger turbine gas side and how exhaust gas quality affects it • Relationship between incomplete combustion and soot/particulate deposits • How exhaust leaks and cylinder oil can introduce contaminants into exhaust flow

💭 Think About

• For each option, ask yourself: Does this condition add unburned fuel, oil, or other solids into the exhaust gas that passes over the turbine blades? • Think about what happens inside the cylinder if combustion is not clean or if too much lubricating oil is entering the combustion space. • Consider what a leaking exhaust valve would allow into the exhaust manifold and how that might affect gas flow and cleanliness at the turbocharger.

✅ Before You Answer

• For each choice, decide: does it increase soot or oil carryover into the exhaust stream? • Check whether the condition would change exhaust gas temperature or quality in a way that encourages deposits. • Verify if each listed condition is independently capable of causing deposits on the turbine blades.
