The reason of throttle carbon deposition, why throttle carbon deposition?

After the car is used for a period of time, there will be many problems, such as the wear and tear of mechanical parts, carbon deposition and so on, so car maintenance is very important. If the car is not properly maintained, some faults will occur. If you find that your car's idle speed is unstable, fuel consumption increases and power performance decreases, it is probably caused by carbon deposition on the accelerator.

Causes of carbon deposition in throttle valve

Throttle carbon deposition may be caused by many reasons, including poor fuel quality and poor air quality, resulting in incomplete fuel combustion; Oil leakage from the valve oil seal causes the recovery system to be unable to absorb oil; The road condition is bad, the speed is slow, the time for the engine to reach normal temperature increases, and the evaporation speed of gasoline after spraying on the back of the valve is slow; In addition, it may also be a series of reasons, such as oil failure, cylinder pressure problem, cylinder bed water leakage and so on. , leading to carbon deposition.

Harm of Throttle Carbon Deposition

Mild or moderate carbon deposition has little effect on daily driving, but has great influence on idle working conditions. When idling, the throttle opening is very small, and carbon deposition will further reduce the intake air at idling, resulting in unstable engine operation and even flameout. In addition, failures such as decreased power, increased fuel consumption, weak driving and increased emission of exhaust pollutants may lead to valve combustion, premature combustion, cylinder explosion or even scrapping in serious cases.

Clean throttle valve

In fact, it is not difficult to clean the throttle. Just remove the accelerator and clean it with detergent. However, it should be noted that if the throttle is moved or the wiring of the throttle sensor is removed during cleaning, the ignition switch should be turned to the on position before starting the vehicle, and the vehicle should be started after the engine is relearned.

However, it should be noted that the throttle does not need to be cleaned frequently. If it is always cleaned, it is not good, it is easy to destroy the structure and affect the work effect.

It should be inevitable that cars produce carbon deposits. In addition to the throttle, such as spark plug, combustion chamber, intake pipe, etc., we should not only do regular maintenance, but also maintain good driving habits to reduce the damage of some key components in the car.
