Solutions <\/em><\/strong>can be to do the following if you have the necessary skills.<\/p>\n\n\n\nFor a petrol car, you need to clean the air filters, replace oxygen sensors and replace or fix the auto computer (ECU).<\/p>\n\n\n\n
For diesel cars, you need to clean the air filters and combustion system, check piston rings, invest in a common-rail fuel injection system, and use fuel detergent additives.<\/p>\n\n\n\n
There may only be one of these causing a problem, so it is best to take your car to a mechanic or service center.<\/p>\n\n\n\n
d)\u00a0A black smoke when accelerating<\/strong><\/p>\n\n\n\n Possible causes <\/em><\/strong>area leaky fuel injector, faulty oxygen sensor or MAF sensor, too much fuel pressure. There can be a computer engine fault. It can also be caused by hard acceleration.<\/p>\n\n\n\nThe fuel mixture can be too rich. There can be a stuck choke, a faulty fuel pump, or your carburetor might need to be adjusted.<\/p>\n\n\n\n
The solution <\/em><\/strong>is to replace any faulty parts if you have the required knowledge. Otherwise, it is best to take your car to the mechanic or service center.<\/p>\n\n\n\ne) Black smoke from the exhaust when revving<\/strong><\/p>\n\n\n\nA possible cause <\/em><\/strong>is most likely a dirty air filter. This is an indication the fuel is not being burned correctly. This can cause a solid carbon residue which then produces black smoke when revving your car.<\/p>\n\n\n\nSolutions <\/em><\/strong>are simply cleaning the air filter. If this does not solve the problem, then take your car to your mechanic or service center.<\/p>\n\n\n\nf) Black smoke on startup then disappears<\/strong><\/p>\n\n\n\nA possible cause <\/em><\/strong>can be as simple as residual soot build-up in the exhaust pipe. Once it is burned away, then exhaust smoke will become clear. As stated above, if the smoke does not clear quickly, it can indicate a more serious problem.<\/p>\n\n\n\nSolutions <\/em><\/strong>can be to monitor the exhaust color and how quickly the black smoke is burned away. The longer the black exhaust smoke occurs, the more serious it can be. It is advised to take your car to the mechanic or service center.<\/p>\n\n\n\nIf you have the required skills, you can replace the necessary parts.<\/p>\n\n\n\n
g)\u00a0Car shaking and smoking from hood<\/strong><\/p>\n\n\n\n A possible cause <\/em><\/strong>can be from oil or fluids that have been spilled onto the engine or exhaust system. It can be oil or fluids that are leaking onto a hot engine or the exhaust system.<\/p>\n\n\n\nBesides oil, the fluids can be engine coolant, power steering, brake, or transmission fluid. It can also be a window washing solvent.<\/p>\n\n\n\n
The solutions <\/em><\/strong>are to pull the car over as soon as possible. Check if any warning lights have come on.<\/p>\n\n\n\nCheck if there are any liquids dripping from the engine onto parts or onto the ground, then the car is no longer safe to drive. Do NOT touch the hot engine.<\/p>\n\n\n\n
If you continue to drive, you can cause serious damage to the engine.<\/p>\n\n\n\n
If you are not sure, then call a tow truck.<\/p>\n\n\n\n
<\/span>FAQ<\/strong><\/span><\/h2>\n\n\n\n- Is it illegal to drive a car with black exhaust smoke?<\/strong><\/li><\/ul>\n\n\n\n
