▌Function of the Cummins Fuel Injector
The fuel injector delivers a controlled quantity of diesel fuel into the combustion chamber or designated injection point, depending on the engine’s fuel system design. Its spray characteristics and injection timing affect how fuel mixes with air and burns during engine operation.
A worn or faulty injector may contribute to hard starting, rough running, excessive exhaust smoke, uneven engine performance, or increased fuel consumption. These symptoms can also be caused by fuel filters, pumps, sensors, wiring, or other engine problems. Proper diagnosis is recommended before replacing the injector.
