Fuel Injection Pump Working Principle - Animation Apr 2026

: Features individual plunger units for each engine cylinder, common in larger diesel engines.

: 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. Fuel Injection pump working principle - Animation

: 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 : Features individual plunger units for each engine

: As the plunger reaches the bottom of its stroke, fuel from the supply tank floods the barrel through inlet ports . This changes the position of the helix, determining

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

: When the pressure is high enough to overcome the spring force of the delivery valve , it snaps open, sending a high-pressure pulse of fuel through the lines to the injectors.
