Fuel Injection Pump Working Principle - Animation -

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

: 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.

: In modern systems, an Electronic Control Unit (ECU) uses signals to trigger high-pressure solenoid valves , replacing the mechanical rack and governor for more precise control. : Uses a single pumping element and a

: As the plunger reaches the bottom of its stroke, fuel from the supply tank floods the barrel through inlet ports . Common Pump Types in Animations : In modern

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.
