In the process of driving, there is a phenomenon that most of the gasoline entering the cylinder will not be burned sufficiently, and carbon deposits will be formed. It may be related to driving Xi, slamming on the brakes, slamming the accelerator, and starting the car for a long time without opening, all of which can cause gasoline to not burn completely. This may also be related to road conditions, and driving at low speeds in urban areas for long periods of time is also prone to carbon deposits.
Carbon deposits can occur on spark plugs and can also easily occur on throttle valves.
The maintenance of the spark plug should not be neglected
In daily maintenance, many people think that the oil and the three filters are the most critical, and the others are completely eliminated according to age. Of course, the spark plug is also included in the large items, and it is not possible to let the spark plug die until it is driven for tens of thousands of kilometers. However, it is important to know that the spark plug is small in size and has a lot of energy, which is related to the stability of the engine, and the ignition of the engine is indispensable. Not only does it ignite, but the spark plug is also waiting for the engine while it is working. The spark plug, in turn, is located at the top of the engine and is most susceptible to carbon build-up. As long as the combustion chamber is insufficient, the excess amount of oil, with the cooperation of air and impurities, is properly attached to the spark plug, and with the help of high temperature, it will become carbon deposit over time, resulting in poor conductivity of the spark plug.
For vehicles with long kilometers, even if the purse factor is taken into account, the spark plug should be replaced in time. If you just give the spark plug a big cleaning, at most let the spark plug be used for some more time, and treat the symptoms rather than the root cause. When it's time to retire the spark plug, it's time to retire it, and who calls him an ignition player.
