1, plus high-grade gasoline, you can reduce carbon it?
Mainly carbon impurities in the gasoline, and dust particles in the air, settling down in the combustion chamber is formed. High grade gasoline, relatively fewer impurities, able to do so using high-grade gasoline, the engine really good.
Similarly, do not often run very dusty road, regularly clean up the air grid (air filtration), can also play a role in reducing carbon. Every 20,000 km, it is best to replace the air cells, and cleaning fuel injectors, throttle. If you save this amount of money, if the engine needs an overhaul because coke serious, but just runs the risk of.

2, prolonged idling, parking air conditioning can cause carbon it?
Do not allow the vehicle to idle for a long time, especially not a long time idling air conditioning is right. "The water temperature at 85 ~ 90 ℃, the engine will be in the best working condition, otherwise incomplete combustion of gasoline, the more carbon. From this reason that, in the morning long hot car, the engine temperature rises very slowly, can also cause carbon Air conditioning is running at idle, the engine will cause more load. "However, Ma also believes that director does not have to do too much, if others need only a few minutes, no need to turn off. Because instant restart, not only high fuel consumption, will cause wear and tear on the engine.

3, running speed can wash away the carbon it?

Run high-speed, we can really take advantage of the airflow airway erosion, washed away part of the coke. So just go out if there are two options to go high-speed, national highway, you may choose to pull one back speed. However, Ma, director of the view that if the special order "obliterated coke" specifically to run high-speed, it is not necessary. "A waste of time, and expensive oil, but also spend a high speed tolls, the effect might as well go 4s shops to do maintenance too!"
