Much black smoke Mazda BT 50 2008 TD

Hello everyone I have a Pik-Up Mazda BT 50 2008 TD, the engine is 12 valves, (I comment on the engine because I have seen that there are different motorizations of that same year.


fact is that it is done a lot And thank you very much for the answers

It may be a problem in the temperature sensor, check its correct operation.
(I spend in a Toyota Cammon Rail)
luck, and I hope someone can help you.

Thank you Guillermo, to see if I find out where the sensor is, anyway I have changed filters, oil, I have cleaned the engine with an additive, I have put a clean injectors, already improved a lot, almost not made that black Humazo (it was the air filter), it only does when I accelerate a lot. I don't know if I do not do it because I have not started it cold, tomorrow I will see, maybe with a little lucky luck.

By smoke theme also testing the exhaust tube since in this Ollin accumulates it is simple to make it very much that improves

Well, it seems that something has improved with what I did to him, he hardly varies the release, just a pelin, so I will continue to miss the additive to the diesel.
I have also cleaned the admission collector, and the escape ... They had carbonilla to bore, and now I will see if the EGR valve cleaned, but I don't know exactly what it is, could anyone tell me?
