How to solve the black smoke from diesel engine?

black smoke from diesel engine

We discussed the reasons for the black smoke of diesel engines in the last article and today we continue to discuss how to solve the black smoke from diesel engines. So far, we have concluded that the black smoke from a diesel engine exhaust is usually caused by a bad fuel/air mixture. To prevent further damage to your car, it’s important to take care of the issues as soon as you notice anything wrong. This will save you money and headaches.

There are several things you can do when you notice black smoke coming out from your exhaust:

  • Always ask a specialist. Our Company’s authorized service can help you with any problems with your diesel car.

  • Clean the air system. As we have mentioned, the right amount of air is important to run your diesel engine properly, otherwise, the fuel will burn only partially. If your air filter is dirty or clogged, you should consider cleaning it or even better – replacing it.

  • Check your engine rings. If the engine piston rings are damaged, that can cause black smoke from exhaust when accelerating. You want to make sure that that’s not the case by checking them in an auto repair shop, and if necessary – replace them. This will prevent the black smoke too.

  • Check the fuel supply. The timing of fuel injection is important too. If the injected fuel is too much, incomplete combustion will occur. The right action is to have the fuel pump and the injection system inspected by a professional mechanic. It’s also a good idea to upgrade them with a common-rail injection system, which feeds fuel directly to the solenoid valves. This way, the car will produce less black smoke out of the exhaust.

  • Use fuel additives. Driving a diesel car daily with a regular fuel could cause a debris build-up in the cylinder chamber and fuel injectors. This will result in a lower performance of the engine and therefore, a lower fuel economy. That’s another thing that causes more black smoke from the exhaust when accelerating the vehicle.

    So, as a conclusion, consider mixing diesel fuel with a high-quality fuel additive. This way, the fuel will not form deposits in the engine, which, in result, will not emit black smoke.
