Is it normal to have black carbon in the exhaust pipe?

In some cases, people look at the exhaust pipe of their own cars after parking, and the exhaust pipe of others' cars is only a little gray-black. What is the reason for such a big difference? How to deal with the problem of black carbon in exhaust pipe? Today I will help you solve this problem completely.

At first, it is normal for the exhaust pipe to be gray and black, but if the exhaust pipe is too black, it is not normal. The black carbon on the exhaust pipe is the substance left after the incomplete combustion of automobile gasoline, which is actually commonly known as carbon deposit. There are several reasons for carbon deposition.

1. Cars often drive at waiting speed or low gear, resulting in increased carbon deposition. The first factor is that the waiting speed/hour ratio of automobile engine is very low, and the concentration of mixed gas entering the cylinder is very high, which is very easy to cause carbon deposition.

2. The three-way catalytic converter has been cleaned for a long time.

3. The spark plug of the car has been removed for a long time, so it can't strike the fire normally and reasonably.

4. Use fake and inferior automobile oil or automobile gasoline.

5. Due to the different gasoline injection modes of automobile engines, the automobile engines with in-cylinder direct injection engines are prone to carbon deposition.

How to solve the problem of black carbon exhaust pipe?

1. Clean or replace the three-way catalyst.

2. Replace the spark plug, and pay attention to the model and specification when replacing the spark plug.

3. Change the high-quality automobile oil to the gas station of the first-line brand for oil supply.

4. Transformation of gasoline and diesel catalytic device.

5. Clean the throttle and air intake system to maintain sufficient air intake and supply.

6. Minimize the waiting time.

Therefore, drivers with serious carbon deposits should pay attention to the maintenance of their cars. Carbon deposition can easily lead to a serious decline in automobile driving force and an increase in fuel consumption. Secondly, the choice of refined oil is also very important.
