How to avoid the accumulation of carbon?
Cars take a long time to burn the oil to produce carbon deposits, which will increase the fuel consumption of the car, and some professionals have pointed out that driving more than 20,000 kilometers, it should be cleaned up, so that the life of the car is better, also Preventing the wear of the parts, and the carbon deposition can not be avoided. There is a carbon deposit in the fuel. The carbon is the waste gas, which is produced by the gasoline with a very high purity, or bad operating habits. The heat production and kinetic energy need to be oxidized. In this process, a gelatinous substance is formed, which is the prototype of carbon deposit. If it is not very good gasoline, there is more glue, and these things are burned again, decomposed and combined. As a result of the formation of carbon, and can not burn, it has been piled up in the car.
The first point: There are a lot of people who are quenching fire very fast. When they see the place, they stop and stop the fire. In fact, if they turn off the flame quickly, some of the burning gasoline will not burn out, so it will settle down. Slowly, carbon deposits are formed. It is best to wait for 30 seconds to 1 minute to extinguish the flames and let the gasoline burn out. Secondly, don't let the car be in a state of completion, that is, continue to run at low speed, such as a traffic jam. In the case, the car can stop and go, it is the most likely to form carbon deposits, so there is a chance to pull the car to the high speed and run, the speed is fast, and the airway will be washed away. Carbon will be less.
Second point: Inject good quality oil. As mentioned earlier, carbon deposition is a substance produced by insufficient combustion in fuel. Therefore, we must choose a regular gas station when refueling, the quality of the oil is relatively guaranteed, but it is worth noting that the high quality is not a high number, the number represents the octane number of the oil, which is related to the engine work. The cylinder knock problem. The third point: regular cleaning of the throttle. The effect of controlling the amount of intake air is achieved by cleaning the throttle. Before cleaning the throttle, first turn off the ignition switch, remove the battery negative, remove the throttle line, remove the intake hose, and remove the screw that fixes the throttle. After removing the throttle, use the cleaning agent to repeatedly clean the throttle. If it is not easy to clean, wipe it with a cotton thread.
Therefore, any car that runs on a congested city road for a long time has a lot of carbon deposits, because traffic congestion brings frequent start and stop, frequent acceleration of oil supply, so the air-fuel ratio is at a lower level for a long time. If the concentration of the mixed gas is too high, the fuel will not be completely burned, and it will become carbon deposit! Therefore, if you want to accumulate less carbon, you must have more "uniform cruising", so running high speed is a very good choice. The high-speed, national road and provincial roads are very good for suppressing carbon deposits! Even if you are driving in a traffic jam in the urban area, try to avoid the big foot throttle. In other words, don't let the fuel spray so much, so thick, try to avoid frequent rapid acceleration.
