Why is there excessive black smoke coming from my Doosan D45S-5?
- A
  alex17Aug 8, 2025
  Excessive black smoke from your Doosan Engine may be due to several reasons. The air cleaner element might be clogged, so try replacing or cleaning it. There could be restrictions in the air duct, which you should check and correct. Another potential cause is leakage at the intake manifold, so inspect and fix that as well. The turbocharger could be seized up and not rotating, or the turbine and compressor blades might be damaged or in contact with each other, requiring disassembly, repair, or replacement. Finally, the exhaust piping could be deformed or clogged; check and correct it.
