Black Smoke Billows On The Udyan Express!
What causes all of that smoke in a diesel engine?
You would think that the locomotive could not function with all of that build up of soot and carbon.
The causes could be bad injectors, or turbocharger or even a bad piston ring. Non the less, these locomotives always seem to turn over and run after a while.
- White smoke is usually coolant burning
- Blue smoke is usually oil burning
- Black smoke is usually a fuel mixture that is too rich
Rich mixture can be caused by a bad fuel controller, restrictive inlet conditions, or bad injectors.
Whatever the cause, there is a lot of smoke!
Let us know why you think the black smoke comes out of the engine like a volcano! We want to know!
