How to judge whether the engine has carbon deposit? In these cases, we are close to each other.

I believe that car owners should know that no matter what the quality of the car is, after a period of use, the engine will produce carbon deposits. If the engine has too much carbon deposits, it will lead to increased fuel consumption or other effects, and even seriously damage the engine. Therefore, one of the most common things we usually do to maintain cars is to clean up the carbon deposits in the engine, but how can we know if the engine has carbon deposits? Actually, it's very simple! How to judge whether the engine has carbon deposit? In these circumstances, we are very close!

Observe fuel consumption. When the spark plug and the fuel nozzle deposit carbon, they will absorb a part of the oil injected into the cylinder, so these oils cannot be completely burned. This not only increases fuel consumption, but also leads to more carbon deposition in the engine oil that is not completely burned. Moreover, the fuel is still not completely burned, and new carbon deposits are constantly produced and attached to the internal parts of the engine, forming a vicious circle.

The second is the instability at idle speed. If we run at idle speed, the engine state is sometimes too high and sometimes too low, and even occasionally the engine jitter can be obviously felt. If this problem occurs when we are idling, it means that the situation of our car engine and our throttle may not be optimistic and needs to be dealt with in time.

In addition, you can observe whether the front car has a pungent feeling before starting the car, indicating that there are more carbon deposits and the fuel consumption increases sharply when driving. These are all signs of more carbon deposits. We all know that the exhaust gas emitted by ordinary gasoline vehicles is similar, but if we find that the exhaust gas emitted by our vehicles is pungent and strange, it may also be a reaction of carbon deposition inside the engine!
