🔍 Key Concepts

• Four-stroke diesel cycle events (intake, compression, power, exhaust) and where valve overlap occurs • What scavenging means in a turbocharged engine (clearing exhaust, filling with fresh air) • Relationship of intake and exhaust valves during overlap and how turbocharger boost affects cylinder pressure

💭 Think About

• In a four-stroke cycle, at what point are both inlet and exhaust valves in some engines intentionally open at the same time, and why? • If the goal is to clear exhaust gases and fill with fresh air, what valve positions and pressure conditions would best accomplish that? • Which choices describe conditions that would actually make scavenging ineffective or impossible in a turbocharged engine?

✅ Before You Answer

• Verify what valve overlap is and when it occurs in the four-stroke cycle • Check whether scavenging can occur with only the exhaust valve open in a four-stroke turbocharged engine • Think about whether turbocharged scavenging would be done at below atmospheric pressure or with elevated intake pressure
