What Causes Black Smoke from Diesel Engines?

[TheoAnn]

Here are the specific reasons for black smoke from diesel engines: 1. Poor diesel quality. The performance indicators of the diesel used do not meet the standard requirements, resulting in poor fuel combustion and black smoke. 2. Blocked air intake. Insufficient air supply during diesel combustion leads to incomplete combustion, causing the diesel engine to emit black smoke. 3. Insufficient compression force. The required pressure does not meet the combustion requirements, worsening the combustion conditions and resulting in black smoke from the diesel engine. 4. Changes in the combustion environment. Long-term use of the diesel engine and other factors can alter the shape and volume of the combustion chamber, further degrading the quality of the fuel-air mixture. Poor mixing leads to suboptimal combustion conditions and the production of black smoke.
