🔍 Key Concepts

• Four-stroke diesel cycle and what happens in each stroke (intake, compression, power, exhaust) • How crankshaft position relates pistons in an in-line multi-cylinder engine (pistons can be paired/opposed in phase) • How a firing order like 1-5-3-6-2-4 spaces out power strokes over 720° of crank rotation in a four-stroke engine

💭 Think About

• First, list the four strokes in order and note at which stroke the piston is at top dead center (TDC) and bottom dead center (BDC) • Think about how many degrees of crankshaft rotation occur between firing events in a six-cylinder four-stroke engine, and what that means for the relative positions of pistons #1 and #2 when #2 fires • Consider which pistons in an in-line six are typically at TDC together (one on compression/power, the other on exhaust/intake) and how that ties to the firing order

✅ Before You Answer

• Verify which strokes have the piston at or near top dead center (TDC) and which have it at or near bottom dead center (BDC) • Check that in a four-stroke cycle the crankshaft must rotate 720° for a full cycle and that firing events are evenly spaced over this rotation • Make sure your chosen option for piston #1’s position is consistent with both the firing order and the need for even spacing of power strokes across all six cylinders
