🔍 Key Concepts

• Engine is a 4-stroke (4-cycle) diesel, so one complete cycle is 720° of crankshaft rotation • There are 16 cylinders, so firings are equally spaced over 720° • Use the firing order given: 1L—8R—4L—5R—7L—2R—3L—6R—8L—1R—5L—4R—2L—7R—6L—3R

💭 Think About

• How many total degrees of crankshaft rotation occur in one full 4-stroke operating cycle for a single cylinder? • If those 720° are shared equally by 16 cylinders, how many degrees of crankshaft rotation occur between successive cylinder firings? • Starting at 1L in the firing order, how many firing "steps" do you pass before you get to 4L, and what is that number of steps times the degrees per step?

✅ Before You Answer

• Confirm the engine is 4-cycle, not 2-cycle, before using 720° for one cycle • Count the cylinders correctly from the data plate: 16 cylinders total • Trace the firing order carefully from 1L forward to 4L, counting the number of firing intervals (steps) between them, then multiply by the degrees per firing interval
