🔍 Key Concepts

• Camshaft and cam lobes – what do the lobes physically push or control in a diesel engine? • Timing vs. performance – difference between mechanical events (open/close/movement) and resulting performance (power, efficiency, pressure). • Valve and injection events – what events must be precisely sequenced in each cylinder?

💭 Think About

• Look at each choice and ask: which items are directly and mechanically determined by the shape and position of the cams themselves? • Which group describes events in the cylinder that must be timed relative to crankshaft position, rather than overall engine output numbers? • Which items would change immediately if you ground a different cam profile, even if nothing else in the engine changed?

✅ Before You Answer

• Verify which components the cam lobes actually act on: valves and/or fuel injection pumps, not pistons or turbochargers. • Check which answer choice is about timing and movement (when and how far something opens) rather than about results like power, efficiency, or pressures. • Confirm that the correct group involves things that must occur in a precise sequence for each cylinder.
