Engine Health: Component Function and Diagnostics

A serious operational issue in the Cummins QSK45 is **Black Smoke and Low Power**, often caused by inadequate airflow or over-fueling, typically indicating a Turbocharger or Injector fault.

Fault & Solution: When a Caterpillar 777G Off-Highway Truck (running a high-capacity engine) produces thick black smoke, check for restricted air filters or boost leaks. If not found, the solution often involves removing and testing the fuel injectors for correct spray pattern and volume, or inspecting the turbocharger for damaged turbine wheels.
