🔍 Key Concepts

• Fuel injection pump plunger and barrel construction and how the helix controls spill port opening • Function of the control rack and gear (component E and the small gear it drives) in changing fuel quantity • Relationship between plunger rotation, effective stroke, and amount of fuel discharged on each stroke

💭 Think About

• When component E moves to the left, what happens to the small gear and the angular position of the plunger helix relative to the spill port? • If the spill port is uncovered earlier in the plunger stroke, does that make the effective pumping stroke longer or shorter, and what does that do to the volume of fuel delivered? • Which of the choices directly relates to changing the effective stroke of the plunger versus changes that are just consequences in the engine cylinder?

✅ Before You Answer

• Identify which labeled parts are the plunger, helix, and spill port, and how they line up at the end of injection • Trace one full upward stroke of the plunger with two different angular positions to see when spill begins in each case • Make sure your final choice matches the idea of a governor rack: it primarily changes fuel quantity per stroke, not basic pump pressure rating or cylinder mean effective pressure directly
