🔍 Key Concepts

• valve overlap in four-stroke diesel engines • purpose of turbocharging and scavenging • gas flow through cylinder during the exhaust and intake strokes

💭 Think About

• Think about what happens to the burned gases in the cylinder as the piston passes through top dead center between the exhaust and intake strokes. • Ask yourself why a turbocharged engine would benefit from having both valves slightly open at the same time. • Consider which option describes the overall flow of air and exhaust rather than a minor side effect.

✅ Before You Answer

• Identify which choice explains the main design purpose of opening both valves near top dead center, not a secondary effect. • Check which option is about gas exchange and cylinder clearing, not about mechanical sizing or condensate. • Confirm that the correct choice relates directly to improving cylinder charging with fresh air in a turbocharged engine.
