How often do you remove carbon deposits from cars?

Depending on the situation, cars driving in urban areas should be cleaned every 20,000-30,000 kilometers, and cars driving on expressways should be cleaned every 30,000-40,000 kilometers.

The owner can check the carbon deposit according to the maintenance manual of the local vehicle and the cycle of replacing the spark plug, and then carry out the necessary carbon deposit cleaning. The general maintenance manual suggests that the spark plug should be replaced within 20,000-30,000 km, so it is more appropriate to clean up the engine carbon deposit when replacing the spark plug within 20,000-30,000 km.

That is to say, under the premise of not disassembling the engine, special equipment is used to remove the carbon deposits in the air intake, valve and oil circuit of the vehicle.

Methods to reduce the formation of automobile carbon deposit

1, use high quality fuel.

Because the main components of carbon deposit are formed by wax and gum deposition in fuel, the lower the gum content in fuel, the better. However, we can't change the quality of fuel, but we can choose not to add low-priced fuel from unknown sources.

2. Try to run at high speed.

When the vehicle is driving at high speed, the engine has a large intake and exhaust volume, and some carbon deposits can be blown out of the engine. Therefore, if you want to reduce car carbon deposition, you must run high-speed regularly, and the effect is not good if the time is too short. Generally, it is better to run at a high speed once every 2000 kilometers. Try to choose a place with good road conditions and few vehicles when driving at high speed.

3. Don't be idle for a long time.

The longer the idle time, the longer it takes for the engine to reach normal temperature, the slower the evaporation rate of gasoline sprayed on the back of the valve, and the carbon deposition will also occur. At the same time, often idling, the air flow into the engine is also small, so the scouring effect on carbon deposits becomes weak, which will promote the deposition of carbon deposits.
