Do I need to clean the carbon deposits in the cylinder to replace the spark plug?How often does the spark plug deposit carbon?

To replace the spark plug, it is necessary to clean the carbon deposit in the cylinder, and the cycle of cleaning the carbon deposit in the spark plug of each car is different, and even the same one sometimes has a difference. Generally, a car driving in a city is recommended to be cleaned every 20,000 kilometers, but often A car running at high speed can be cleaned once for 30,000 to 40,000 kilometers.

In addition to reference based on the number of kilometers, we can also make a judgment based on the actual situation of the vehicle. The following situations are excessive carbon deposits and need to be cleaned up.

1. It takes many times to start normally when the car is cold;

2. The speed is slow and the acceleration is weak;

3. Exhaust gas is not up to standard and has a pungent smell;

4. Compared with the past, fuel consumption has increased.

When the above situation occurs, it can be preliminarily judged that the spark plug has excessive carbon deposits, and further cleaning of the spark plug is required.

With the use of spark plugs, carbon deposits are generated, and car owners need to remove them in time so that the spark plugs can work normally. Although the spark plug seems to be a small part, it plays an important role. Without the ignition function of the spark plug, the engine will not be able to work and the vehicle will not be able to start.

In addition to removing carbon deposits and maintenance, spark plugs must be replaced in time. Spark plugs have a certain period of use, and their service life is related to factors such as electrode material and spark plug brand. Generally, ordinary nickel alloy spark plugs need to be replaced after they are used for about 20,000 kilometers. Once, the service life is the shortest; platinum alloy spark plugs can be replaced at about 40,000 kilometers; iridium spark plugs can be replaced at about 60,000 to 80,000 kilometers, and the service life is longer. But these are just some reference values, and it depends on the usage of the spark plug.
