Q

The power output of a turbo-charged diesel engine will drop if the cooling water flow through the after cooler is interrupted because the __________.

🔍 Key Concepts

• Turbo-charged diesel engine air flow path from turbocharger to aftercooler to cylinders • Effect of air temperature on air density going into the cylinders • Purpose of an aftercooler (intercooler) in an engine’s induction system

💭 Think About

• Think about what happens to the intake air temperature if cooling water flow through the aftercooler stops. • How does hotter or cooler intake air change the amount of oxygen entering the cylinder for each stroke? • Which choice describes a change that would directly reduce the engine’s power output, rather than being a secondary or unlikely effect?

✅ Before You Answer

• Verify the main function of the aftercooler (does it cool air or exhaust?). • Consider whether the turbocharger itself depends directly on the aftercooler water flow to keep spinning. • Check which option best matches the idea of changing mass of air per cycle entering the cylinders.
