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.
: 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.
