How to remove carbon deposits? Is the black powder on the exhaust pipe carbon deposit?

Generally, after driving in the urban area for a period of time, the car will feel weak, the engine noise will become louder and the fuel consumption will become higher. Experienced drivers will tell you that this is because the engine has a lot of carbon deposits. I suggest you go running on the highway. What is engine carbon deposit? Why is it much better to run on the highway? From the principle of carbon deposition, the first thing to remove carbon deposition is to make the mixture in the engine cylinder burn fully to reduce the generation of carbon deposition. When driving, avoid kicking the accelerator, avoid sudden acceleration and deceleration, keep the vehicle running in the best efficiency working condition as much as possible, and reduce the idle running time of the vehicle.

Strictly speaking, it should not be carbon deposit on the accelerator, but rather sludge! During the operation of the engine, a part of engine oil vapor will enter the intake manifold through the forced ventilation process of the engine crankshaft through the PCV valve, and this part of engine oil will adhere to the back of the low-temperature throttle, and then mix with the dust in the intake air, resulting in sludge on the back of the throttle. These sludge will change the air intake of the engine, make the engine idling unstable and increase fuel consumption. Sludge engine will be compensated by throttle deflection angle to a certain extent, but it can only be removed by cleaning after exceeding a certain limit.

Physical removal is the best way to remove carbon deposits from automobiles. Softening the bottle has no effect. Excessive carbon deposition at the intake will cause the ejected fuel to be adsorbed by carbon deposition and form an oil film. This is also one of the reasons why cars will be weak and fuel consumption will become higher after too much carbon deposition. Physical cleaning method can remove the intake pipe and clean it with cleaning agent and small brush. Of course, there are more advanced walnut sand cleaning equipment now, and the effect is also very good.

Another bottle of magic gold liquid was used, and no black spots could be seen through the top of the spark plug. Anyway, I feel that both of them are good for carbon deposition. But I don't think a bottle will be cleaned. Then, it is recommended that Li Mo and domestic hurricane Macarbon are invincible. I haven't used hurricane Macarbon invincible, but I feel that the effect of hurricane Macarbon invincible is as good as or even better than the magical gold liquid.
