Fuel Injection Pump Working Principle - Animation Link

: Driven by the engine's camshaft, the plunger moves upward. Once it covers the barrel ports, the trapped fuel begins to compress.

: 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.

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. This changes the position of the helix, determining

: Uses a single pumping element and a rotor to distribute fuel to all cylinders in sequence, typically found in smaller vehicles.
