🔍 Key Concepts

• Use the Top Dead Center degrees in the table to find the angular spacing between cylinders #9 and #8 • Recall how a two-stroke cycle works: one revolution (360°) = power + compression, with scavenging/exhaust near bottom dead center • Relate crank angle position (before or after TDC) to whether the piston is on compression, power, intake, or exhaust in a two-stroke diesel

💭 Think About

• First, shift the reference so that cylinder #9 is at 0°. What crank angle does cylinder #8 then have? • Is cylinder #8 closer to top dead center or bottom dead center, and is it traveling upward or downward at that point in the cycle? • In a two-stroke, which part of the stroke occurs as the piston moves upward toward TDC after passing the scavenging/exhaust ports?

✅ Before You Answer

• Be sure you are using the difference in degrees between #9 and #8 from the chart, not just reading one value • Confirm your mental picture of the two-stroke sequence: power → scavenging/intake → compression → power again • Make sure the stroke you choose matches an upward-moving piston approaching TDC rather than a downward-moving piston leaving TDC
