Aftercooling of a turbocharged diesel engine will result in _________.

🔍 Key Concepts

• Turbocharging increases the mass of air entering the cylinders • Aftercooling (intercooling) reduces the temperature of compressed air from the turbocharger • The relationship between air density, fuel burned, torque, and brake horsepower in a diesel engine

💭 Think About

• What happens to air density when hot compressed air from the turbocharger is cooled before entering the cylinders? • If you can get more oxygen-dense air into the cylinder, how does that affect how much fuel you can burn efficiently and the force on the piston? • How are torque (turning force at the crankshaft) and brake horsepower (power output over time) related when an engine can burn more fuel efficiently per cycle?

✅ Before You Answer

• Be clear on the difference between torque (instantaneous twisting force) and brake horsepower (rate of doing work). • Think through whether cooler, denser air would increase or decrease the engine’s effective power output. • Verify in your notes: when diesel engines are both turbocharged and aftercooled, do they typically gain or lose torque and BHP compared to naturally aspirated engines?
