Injector FAQ
FAQ: What are the reasons for black smoke?
ERIKC Answer: Black smoke caused by the post-processing system
In the picture, the black smoke coming out of the accelerator in place is PM, PM. Why is this happening? This is related to the technical route of the country car IV. The technical route of the TG4 is EGR+DOC+POC. EGR introduces exhaust gas into the cylinder, which reduces the combustion temperature. The nitrogen oxides generated by the high temperature and oxygen enrichment produce relatively less, and the temperature is low and the particulate matter is generated more. The particles were then picked up with POC. After they were caught and burned, there was a problem. What kind of burning?
By high temperature exhaust, but many cars running city conditions, the exhaust temperature can not be burned off, it will accumulate in the POC, plug the POC, in situ fiercely step on the throttle, intake and exhaust volume, will put the POC The caught particles blow out to form black smoke. Therefore, if the temperature of the exhaust gas cannot reach the specified temperature during the regular running of urban conditions, then this route cannot achieve a better effect of the particulate matter treatment.
FAQ: What are the reasons for black smoke?
ERIKC Answer: the quality of diesel is not good
The use of inferior fuel oil, or fuel containing water, etc., will cause combustion to deteriorate, resulting in smoke, etc., and will not generate any fault code, and the data flow will not be abnormal. Therefore, when the normal inspection cannot eliminate the fault, try to replace the qualified fuel test ( Or plug a small oil bottle, if necessary, clean fuel lines and components.
FAQ: What are the reasons for black smoke?
ERIKC Answer: injector and related accessories installation failure.
For example, the injector leaks the sealing gasket, the high pressure ejector leaks water, the injector copper leaks, etc.
