🔍 Key Concepts

• Relationship between firing order and crankshaft position in an in-line 6-cylinder, 4-stroke engine • How many crankshaft degrees occur per stroke in a 4-stroke cycle and over a full engine cycle • Which cylinders are on companion positions (move together) in an in-line 6

💭 Think About

• First, determine how many degrees of crankshaft rotation equal one full 4-stroke cycle, and how many degrees between each firing event in a 6-cylinder engine. • Figure out which cylinder is 360° out of phase (same position, opposite stroke) with #1 and which cylinders move together but are 120° or 240° apart. • When #1 is at TDC on its power stroke, what stroke must #3 be on, given its place in the firing order and its crank angle difference from #1?

✅ Before You Answer

• Confirm that a 4-stroke cycle requires two full crankshaft revolutions (720°) to complete all four strokes. • Verify the degree spacing between firing events for a 6-cylinder 4-stroke engine (720° divided by 6). • Check which cylinders reach TDC/BDC together (companion cylinders) and then match this with where #3 falls relative to #1 in the firing sequence.
