The b way to remove carbon deposits by yourself
1, don't turn off the engine too fast. For friends who drive for a long time, as long as they arrive at their destination, they will basically stop and turn off the engine. This behavior is wrong. You know, when the car stops, some fuel will slowly cool down because of the flameout, and then precipitate. If it continues, the carbon deposit will increase. So the correct way is to wait 1 minute or 30 seconds after parking, which will be better.
2. Clean the throttle. The throttle can be removed as long as the decorative cover of the engine is removed. At this time, you can clean it with carburetor cleaner, and finally clean it with cotton cloth and put it back. Individuals buy a bottle of carburetor cleaner, spray it on the throttle and air intake, and scrub it. When we can feel the problems such as idle jitter, starting difficulty, excessive idle speed and excessive exhaust volume, it is time to clean the throttle.
3. Try to improve the shift speed of manual transmission cars. If you have time, run more high-speed, improve shift speed and drive at high speed. The main reason for this is that you can use a lot of air intake to flush the air intake, which can reduce and prevent carbon deposition and improve the power of the car. In this regard, it is suggested that the shift speed should be 2500 ~ 3000 rpm, and it is best to use high-grade gasoline. Of course, it must match the car, otherwise carbon deposition will also occur.
Reasons for carbon deposition:
1, pure gasoline will not produce carbon deposit when burning, but will only produce water, carbon dioxide and some trace gases. If gasoline contains impurities, it will be burned during combustion and form carbon deposit. The more impurities, the more carbon deposits.
2. When the car is turned off, the spark plug is cut off, and some combustible mixture can't be completely burned, forming carbon deposit.
3. The oil and gas in the crankcase forced ventilation system form carbon deposit.
4. The failure of the car itself leads to excessive fuel injection and incomplete combustion leads to carbon deposition. These are the reasons for the formation of carbon deposits in automobiles. However, within100000 km, it will not affect the car. I think friends who have been driving for more than three years should have a deep understanding.
Harm of carbon deposition:
Carbon deposition will directly affect the efficiency of the engine. For example, carbon deposition will cause local temperature to be too high, resulting in surface fire; It will also make the cylinder volume smaller, change the compression ratio, and the cylinder pressure will suddenly rise. It directly causes knocking, and the result of knocking is to weaken the ignition advance angle and directly reduce the maximum power of the engine.
