The issue of black smoke emanating from a CATERPILLAR C9 engine was diagnosed to be caused by faulty injector sleeves and injector seals. Many customers wonder about the connection between injector sleeves and engine knocking. When the engine leaks coolant, it may seep into the cylinders through the faulty injector sleeves, resulting in poor combustion and causing black smoke and cylinder knocking. The integrated design of the cylinder head's diesel passages in the C9 engine exacerbates this issue. Ensuring proper maintenance of injector components is crucial to prevent such problems.
