Black smoke can be caused when there is an improper air to fuel ratio . This can be anything from a plugged air cleaner,injector,turbo....
blown turbo - worn turbo bearing causing oil to suck through and into exhaust manifold - results in no power and neat oil burning in the exhaust - major black smoke
it can be unburned fuel damaged turbo charger etc. light amount of smoke can be normal large amounts = problem.
A faulty turbo is indicated by pure black smoke when engine revs are above idling revs and it can also be shown by poor machine performance.
Black smoke is usually caused by excessive fuel consumption, alot of things can cause this but if the turbo was recently installed, the injection system (controlled by the ECU) needs to be reprogrammed for it.
this will happen on all diesel engines (if its going to make reasonable power) its basically soot/carbon from the exhaust and unburnt diesel. on some high power turbo diesel cars there is proper plumes of black smoke. you only need be worried if there is blue smoke while on boost as this means the turbo is shot. but black = good
Black smoke coming from the exhaust is a symptom of a bad turbo on a Caterpillar C 15. Another symptom is a loss of horsepower.
