Maintenance technicians recommend: try to reduce vehicle idling, the vehicles body shaking when idling, acceleration, vehicle speed fast, sudden increase in fuel consumption. If the vehicle in such a situation, it shows that the engine carbon deposits more, need to be cleaned up. Zhongshan maintenance technicians Fan Liangyin that minimize vehicle idling operation and to run more speed, you can reduce and prevent carbon deposition.
According to reports, the engine is not synchronized with each piston, when the vehicle stalled, the engine cylinder intake valve can not be all closed, and the operating cycles of the ejected gas can not be recovered in time, some of the unburned fuel will continue to oxidation is evaporated, and especially in the intake pipe rear throttle softer produce some carbon black. Fanliang Yin said that when the valve each subsequent formation of coke fuel injected into the cylinder will be a part is absorbed, making the true concentration of the mixture into the cylinder thinning, causing the engine working poor, there will be a vehicle body shaking when idling, accelerating the vehicle speed fast, sudden increase in fuel consumption and other anomalies.
Some owners believe that high-grade oil, the quality will be better, in fact, this is not entirely correct, labels represent oil octane, does not represent the quality and cleanliness. That 97 is not necessarily oily impurities than 93 less. Fanliang Yin said, to reduce the carbon, add appropriate detergent gasoline will have a certain effect.
“Dismantling the engine is certainly the most direct way, but if because of too much coke on dismantling engines, engine life will inevitably have an impact, not worth the candle.” Fanliang Yin said that some car owners driving habits idle, idle driving will reduce access engine air flow, so that the scouring action of carbon becomes weak, will promote the deposition of carbon, therefore, reduce the idle running, multi-run high-speed is a very good way, and this is often said that people pulling speed, pull on the inlet airflow speed is the use of scouring action to prevent carbon deposition.
