The engine has a very black and smoky exhaust, where would you look for trouble?

  1. Find out if the engine is overloaded, check the exhaust pyrometer and see that the cylinders carry an equal amount of the load and adjust fuel valves and spray valves accordingly.
  2. Check fuel oil for cleanliness and water.
  3. Check fuel pumps and fuel lines for entrapped air.
  4. Check scavenging/boost air is enough.
  5. A poor grade of fuel oil may also cause smoky exhaust.
