For older drivers often drive is concerned, when their car for a long time, there will be all kinds of problems, these problems make the dynamic performance of the car significantly reduced, more serious but also directly affect the normal use of the car for traveling security poses a potential risk, for example, when a car drove for a long time after, the engine power will be significantly reduced, while the car’s fuel consumption will increase, automotive cold start problems and unstable idle, engine knocking and other problems.
The main reason is the interior of the car too much carbon these problems arise, there is no timely cleaning, car after prolonged use, the reason for causing performance degradation of these power problem, mainly because of the impact of carbon intake air throttle engine, the impact of closure, and even lead to a lack of cylinder pressure, and nozzle carbon deposition will directly affect the amount of oil will lead to lack of engine oil supply, in addition, the piston can cause serious coke piston scuffing the cylinder wall, resulting in air leakage, more serious is the emergence of the phenomenon of stuck piston rings, which are important causes of insufficient power output of the engine appear.
Of course, due to the structure of the engine itself, the combustion chamber of the engine efficiency is only 30 to 25 percentage — percentage only, therefore carbon deposition phenomenon is mainly caused by the machine itself, carbon deposition is It can not be avoided, but we can reduce engine deposits have generated a sense, keeping in mind the regular clean-up engine deposits, to prevent excessive engine deposits affect the normal use of the car, took a few so we have to drive for everyone way, if you develop these good driving habits, you can say that your car will definitely stay away from these illnesses, make your car more open the more adequate strength.
The first is to let the car run a high-speed, shift-speed to maximize my hand vehicles. The purpose is to run a high-speed airflow to scour inlet to prevent carbon deposition. In addition, increasing the speed of the shift also run a high speed has the same purpose, the original in 2000 when the shift speed becomes 2500 conversion, not only can effectively prevent coke generation, can also increase the power of the car, but also to avoid shifting speed is too low knocking brought protect the engine.
The second is to not let the car idle for a long time in the running of the state. Idling for a long time, launchMachine to normal temperature time also becomes long, the rate of evaporation of gasoline is sprayed onto the back surface of the valve is slow, carbon also arises. At the same time often idle speed, air flow into the engine also small, so scouring effect of carbon deposition becomes too weak, it will promote the deposition of coke.
The third engine maintenance is regularly checked, we in the choice of oil must be used in conjunction with the condition, not to say that the oil price as high as possible, should be more reference vehicle mileage, driving environment and is self-priming engine or turbine, according to the rational use of these oils. Also, attention to the spark plug, the oil passage, a port other easily done by one investigation carbon parts and cleaning, to minimize carbon deposition.
The fourth is noted that the timing of turn off, turn off the engine before the vehicle, if the vehicle running speed is low for a long time recommended that the tread depth flameout kicks in a neutral position throttle, using the high speed operation of the engine at the impact of carbon deposition, and other smooth operation and then turn off. Do not turn off immediately after the high-speed running or climbing, especially models with a turbocharger, since the vehicle is equipped with a turbocharger carbon formation several times faster than the average speed of naturally aspirated vehicle, so try running for a while and then turn off the engine idling car.
Fifth is filling high quality gasoline. Gasoline gum and wax impurities such as carbon formation is the main component, so that a high cleanliness tendency to form coke on gasoline weaker. It is noteworthy that high quality does not mean high-grade gasoline, oil that is not necessarily the number of 97 less than the number of impurity 93, octane numbers represent oil, does not represent the quality and cleanliness. Some owners to ensure the cleanliness of gasoline, the gasoline will be employed in the practice of adding gasoline detergent, which can effectively prevent the formation of carbon layer on the metal surface of the junction, and can be gradually activated gradually remove the original soot particles, whereby protect the engine from damage. But adding gasoline detergent must be careful, if added shoddy products will get the opposite effect.
Summary: The engine produces carbon is a normal phenomenon, it can not be avoided, if the engine deposits is not serious, then it is blind to do some so-called clean-up projects, so not only low cost, andThere may also be damage to other parts of the car. But if we do not pay attention to it, so it will have the power and fuel consumption of cars adversely affected, thus affecting the texture of our car, so for coke or to prevention.
