🔍 Key Concepts

• turbocharging and air density • effect of air temperature on engine power • fuel vs. air limitations in diesel engines

💭 Think About

• Think about what a turbocharger is trying to achieve with the intake air before it enters the cylinders. • How does changing the temperature of the intake air affect its density and the amount of oxygen available for combustion? • Which choices would actually reduce the amount of air (or oxygen) in the cylinder rather than increase it?

✅ Before You Answer

• Compare how heating vs. cooling the intake air changes its density. • Ask yourself whether valve overlap normally helps or hurts cylinder scavenging and filling in turbocharged engines. • Decide which option directly helps you pack more oxygen per intake stroke into the cylinders.
