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.

: Features individual plunger units for each engine cylinder, common in larger diesel engines. Fuel Injection pump working principle - Animation

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. : Uses a single pumping element and a
