🔍 Key Concepts

• Function of exhaust valves in a diesel engine and what they must do every cycle • Difference between valve timing, valve seating, and external system conditions like cooling water or exhaust back pressure • What directly affects whether an exhaust valve opens/closes at the right moment and seals the gases properly

💭 Think About

• Ask yourself: which choice deals with the mechanical action of the valve itself (opening/closing and sealing) rather than outside system conditions? • Consider what would happen if the valve did not seal properly or did not open/close when it should. Which option addresses that most directly? • Which items in the choices can vary somewhat during normal operation without immediately preventing the valve from working at all?

✅ Before You Answer

• Identify which answer choice involves valve movement and sealing rather than temperatures or pressures in the system. • Think about the term timing in relation to camshaft and valve events in an engine cycle. • Verify which factor, if incorrect, would most quickly cause burned valves, loss of compression, or misfiring.
