🔍 Key Concepts

• How effective stroke of the plunger changes as it is rotated from position 1 to 4 in Figure B • Relationship between effective stroke length and the amount of fuel injected per cycle • What fuel setting is required for an engine running at no load, idle RPM compared to full power or shutdown

💭 Think About

• Compare the effective stroke shown in each of the four plunger rotation positions and rank them from maximum fuel to minimum fuel delivery • Think about which position would correspond to full-load fuel, which to fuel shutoff, and which would logically fall at the very low but still-running fuel quantity needed for idle • Ask yourself: at idle with no load, does the engine need the longest, shortest, or an intermediate effective stroke, and which figure visually matches that

✅ Before You Answer

• Verify in Figure B which position has the longest effective stroke (maximum fuel) and which has the shortest but not zero effective stroke • Confirm which rotation position appears to align the plunger port so that fuel is almost immediately spilled (very small effective stroke) versus significantly delayed (large effective stroke) • Make sure the choice you select corresponds to a setting that would allow the engine to just keep running without stalling, not full power and not complete cutoff
