Ways to remove carbon deposits

First: filling high quality gasoline gasoline impurities such as wax and glial is the main ingredient of the formation of coke, so the high cleanliness gasoline formed coke trend weaker. Unfortunately, the quality of China's gasoline is still relatively low compared with developed countries, only crude. We have to pay attention to high-grade does not mean high quality, is the No. 97 oil is not necessarily impurities No. 93 less label represent the octane level of gasoline, and not representative of the quality and cleanliness. Some owners in order to ensure the cleanliness of gasoline, will adopt the to add gasoline detergent practice in gasoline. This can effectively prevent the junction layer, the formation of coke on the metal surface, and the original coke particles can be gradually activated gradually removed, thereby protecting the engine from damage. But gasoline detergent add must be careful, joined the shoddy products will get the opposite effect.
: Do not for a long time idling traveling a long time idling, the engine reaches normal temperature time becomes longer, evaporated gasoline is sprayed into the valve on the back on the slow speed and coke which. Often idling driving the flow of air entering the engine is also small, so that the scouring action of coke becomes weak, and will promote the deposition of coke.
Third: to run high-speed, maximizing the the shift speed manual transmission cars run more than the purpose of the high-speed is to use air scouring action of inlet to prevent carbon deposition. To improve the speed of the shift of multi-run high-speed with the same purpose, the original shift into 2500rpm conversion speed 2000rpm, not only can effectively prevent the generation of coke, also can improve the dynamic performance of the car, and also to avoid the knock shift speed is too low to protect the engine.
Fourth: Use clean fuel cleaning additives to clean the engine clean protective agent is fairly simple, specific use of methods and precautions can see the product instructions. Cleaning agent in engine work, fuel pump along with the fuel sucked into the oil pipeline. With the fuel flow, it can not only wash away the fuel tank the glial fuel pump strainer and nozzle on the glial and coke, so that the engine "rejuvenated" renewed surging power. Washing down from the fuel tank, fuel pump, filter and fuel pipelines the glial will precipitate in the fuel filter after cleaning to avoid demolition must be promptly replaced the fuel filter (petrol grid). Need to be reminded again that the chemical cleaning ingredients of the cleaning agent in the the rubber oil pipeline corrosive effect, when using this method, be sure to pay attention to the life cycle interval, or will accelerate the aging of the fuel rubber oil pipeline and corrosion.
Fifth: disassemble cleansing "to avoid demolition cleansing" simple labor-saving, and only need to use the correct method. But for coke serious engine, this method is not, and can not completely cleaned. Free demolition cleaning, engine performance is still poor, and the technician told you when dismantling the engine, it would have to adopt the method to solve the problem is that the valve and cylinder caused by carbon deposition too.  

Valve soot cleaning is relatively simple, clean drugs, by hand or soaking can be cleared after the Remove the intake manifold. The clean engine cylinder carbon deposition must "go to war" to remove the cylinder head, timing belt can clean. Clean carbon deposits within the engine cylinder should not be due to its power, sealing performance will be inferior engine disassembly reassembly with the original, so under normal circumstances frequently. The last resort to the regular maintenance plant, otherwise the engine performance is greatly reduced.
