Question 1 of 27070

Q

Which of the following problems can cause an above normal air temperature to develop in the intake manifold of a turbocharged and after cooled diesel engine?

🔍 Key Concepts

• Heat exchange in after coolers on turbocharged diesel engines • Effects of cooling water flow on intake air temperature • How air restriction (filters, compressor/turbine problems) affects pressure vs. temperature

💭 Think About

• Think about which option directly affects how much heat is removed from the compressed air before it enters the intake manifold. • Consider which problems mostly change air pressure and flow versus which change cooling effectiveness. • Ask yourself: if this component failed, would the air be cooled less, or simply move less efficiently?

✅ Before You Answer

• Identify which component’s main function is to remove heat from the charge air just before it enters the engine. • For each choice, decide whether it primarily affects compression/flow or cooling. • Verify which condition would let the air reach the intake manifold still hotter than normal after turbocharging.
