What is the purpose of the intake/exhaust valves in a diesel engine?

🔍 Key Concepts

• Diesel engine four-stroke cycle (intake, compression, power, exhaust) • Role of intake valves and exhaust valves in moving gases into and out of the cylinder • Difference between fuel/air handling and lubrication/cooling systems

💭 Think About

• In which part of the engine does the intake/exhaust valve actually sit, and what flows through that space? • During which strokes of a four-stroke diesel cycle are the intake and exhaust valves open, and what are they allowing to happen? • Which answer choices describe systems (lubrication, cooling, ignition) that typically use separate dedicated components rather than the intake/exhaust valves?

✅ Before You Answer

• Make sure the function you choose involves air or exhaust gas flow in and out of the cylinder. • Eliminate any choices that describe functions handled by separate systems (oil pumps, water pumps, fuel injectors, etc.). • Remember that a diesel engine does not use spark ignition in normal operation.
