AutoTalkShowUsually love the car, good driving habits can indeed play a preventive role. Six methods of how to prevent carbon deposition, for riders reference.
1, regular cleaning air filter
Do not often run a lot of road dust, regularly clean up the air cells (air filtration), can also play a role in reducing carbon deposition. Every 20,000 km, it is best to replace the air cell, and clean the fuel injectors, throttle.
2. long time idling, parking air conditioning can cause carbon
Do not allow the vehicle to idle for a long time, especially not for a long time idling air conditioning. The water temperature at 85 ~ 90 , the engine will in the best working condition, or incomplete combustion of gasoline, the more soot. From this reason that morning long hot car, the engine temperature rises very slowly, can also cause carbon deposition. Air conditioning running at idle, but also will result in engine load. If others need only a few minutes, no need to turn off. Because instant restart, not only high fuel consumption, can also cause wear and tear on the engine.
3, high-speed running can be flushed coke
High-speed running, air scour can indeed use the airway, a portion of flush carbon. So, if you just go out there are two options to go high-speed, State Road, then why not choose to pull one back high speed. But if specifically designed to "wash away soot" specifically to run high-speed, it will not be necessary. A waste of time, and expensive oil, but also spend a high speed tolls, the effect might as well go 4S shop do maintenance!
4, to improve the prevention of the shift speed and protect the engine soot generation
Low-speed shift, is often said, "high gear", the car is easy to knock, combustion of gasoline due to inadequate carbon. But artificially increase the shift speed is not necessary - it will improve the fuel consumption and causes premature wear of the clutch friction plate. Therefore, the manual transmission car, 1.6 ~ 2.0L displacement, about 2000 rpm shift is relatively affordable, no need to increase; and automatic car, be careful not to fierce fuel door.
5, the car parked in neutral fierce fuel door, can run as scouring coke with high speed it?
In theory, the idle fierce fuel door will wash away some of the carbon, but this method is not recommended. The first is a waste of gasoline, pollute the environment; secondly, the engine idling is not good. Especially the speed to 4,000 rpm, if it is not running on the road, the wind did not go in to cool the engine, the engine will have an impact. Really rely on air flow to wash away soot, or high speed to run it!
6, the most effective and convenient method of addition to carbon
Carbon or prevention: Do not use lubricants fake inferior to the regular repair shop to do maintenance. If the poor quality of the oil, in a short time can not see the impact, but a year or two down, it can cause serious coke even damage the engine.
