🔍 Key Concepts

• Four-stroke diesel cycle sequence (intake, compression, power, exhaust) • Piston and crankshaft motion: which strokes are downward vs upward • What happens to air and gases (entering or leaving the cylinder) on each stroke

💭 Think About

• For each stroke (intake, compression, power, exhaust), picture what the piston must do: move up or move down? • During which stroke does the cylinder volume increase and during which does it decrease? Relate increasing volume to piston moving down. • Think about when fresh air is drawn in and when exhaust gases are pushed out. Which piston direction would help each of those processes?

✅ Before You Answer

• Be clear on the order of the four strokes in a diesel: which one starts the cycle? • For each named stroke in the choices, decide if the piston is going upward or downward – eliminate any that are clearly upward strokes. • Remember that a four-stroke cycle has two downward and two upward strokes – make sure your choice fits that pattern.
