: To stop injection, a helical groove on the plunger eventually uncovers a spill port . This allows pressurized fuel to "spill" back into the lower-pressure gallery, causing the delivery valve to close instantly.

The primary working principle of a fuel injection pump involves using a reciprocating inside a barrel to pressurize and meter fuel before delivering it to the engine cylinders . In a standard mechanical setup, a camshaft drives the plunger up and down, while a control rack rotates the plunger to adjust how much fuel is injected per stroke. : To stop injection, a helical groove on

: When you press the accelerator, a control rack rotates the plunger. This changes the position of the helix, determining how long the spill port stays covered and, consequently, how much fuel is delivered to the cylinder. Common Pump Types in Animations
