Which of the following conditions may be attributed to a fouled turbocharger compressor inlet screen or filter?

🔍 Key Concepts

• Effect of air intake restriction on turbocharger and diesel engine performance • Relationship between scavenge air pressure, exhaust temperature, and engine load/speed • How a dirty or fouled air filter/screen changes compressor operation and airflow

💭 Think About

• If the air going into the turbocharger is restricted, what happens to the amount of air reaching the cylinders and the scavenge air pressure? • When less air (oxygen) reaches the cylinders, how does that affect combustion quality and exhaust gas temperature? Hotter or cooler? Why? • If the engine is getting less air than it needs at a given fuel setting, what is likely to happen to the maximum speed it can reach under load?

✅ Before You Answer

• Verify how restricted air supply to a turbocharger affects scavenge air pressure readings. • Check typical diesel engine behavior: does poor combustion from low air generally lead to higher or lower exhaust temperatures before the turbine? • Consider whether a drop in air supply alone could realistically cause all three listed symptoms at the same time, or only some of them.
