What Causes Black Smoke and Insufficient Power in Diesel Vehicles?

[LaCooper]

Regarding the specific reasons for black smoke and insufficient power in diesel vehicles: Clogged Air Filter: Exhaust valve leakage, clogged air filter, poor atomization of the fuel injector, and dripping from the fuel nozzle can lead to incomplete fuel combustion, resulting in black smoke. Overly Rich Combustible Mixture: An overly rich combustible mixture, excessive engine oil in the fuel, water in the fuel, or faulty spark plugs can cause insufficient power and black smoke from the exhaust. Incorrect Mixing of Fuel and Oil: Incorrect mixing of fuel and oil, or using the wrong type of oil. If the mixed fuel contains too much oil or the oil quality is poor, the oil in the combustible mixture cannot be completely burned, leading to insufficient power and black smoke from the exhaust.
