🔍 Key Concepts

• Turbocharging and scavenging air systems on marine diesel engines • Effect of temperature on air density (cooler vs warmer air) • Why engines use intercoolers/after coolers between the compressor and intake manifold

💭 Think About

• When air is compressed by a turbocharger or blower, what happens to its temperature and volume? How does that affect how much oxygen gets into the cylinders? • Think about the difference between pressure and density. Can you have the same pressure but different densities depending on temperature? • Which component mainly controls pressure of inlet air, and which component mainly controls its temperature after compression?

✅ Before You Answer

• Identify which device (turbocharger, blower, after cooler) is primarily responsible for raising pressure of intake air • Recall that cooling a gas at roughly the same pressure will change its density in which direction? • Decide whether the main design purpose of an after cooler is to protect the turbo/blower itself, or to improve combustion inside the cylinders
