Coke-impact Engine Teach You How To Prevent Coke - Coke, Causes, Effects - Automotive Repair And
Coke Fuel and lubricants is channeling gas mixture resulting from incomplete combustion of sediment
. (Main ingredient is hydroxy acids, asphalt, tar, etc.) the formation of sediments and the car "fuel" and "oil" directly related: the first is due to "oil" in channeling gas contained carbon particles, in the incomplete burning a lot more deposits. Car itself contains resin and impurities, or the storage and transport process into the dust, impurities, etc., accumulate in the vehicle fuel tank, into the tubing and other parts of the formation of similar sediment sludge; followed by the olefin in gasoline such as stable group were certain temperature, the occurrence of oxidation and polymerization to form a viscous gum and resin-like material. The viscous material in the nozzle, intake valves, combustion chamber (cylinder head and piston top) and other parts will become hard coke deposition. In addition, due to urban traffic congestion, often in low-speed vehicles and Idle State, but will increase the formation and accumulation of these sediments. Japan and South Korea about 30000KMSeries models should be clear about time, because the majority of Japanese and Korean series open-type engine with low turn high twist, focusing on low rpm Travel , Carbon deposition on the engine Power And Fuel consumption Relatively small. On the contrary, Europe and the United States Department of models about 20000KM should be clear about one, mostly in Europe and the United States Department of models of high speed engine reaches a certain speed into the real power was out, mostly in the high-speed driving, but tried the high speed low speed , the impact of carbon deposition on the engine when accelerating at low speeds reflect more evident.
Coke car would impact: 1, reduced engine power 2, increased fuel consumption 3, Cold start Difficulty 4, coke combustion chamber will be a serious blast! Low-speed acceleration with the sound of the piston and crankshaft damage
5, emissions exceeding Solution: First: filling high-quality gasoline. Gasoline impurities such as wax and gum formation of coke is the main component of gasoline so high cleanliness of the trend of formation of coke on the weaker. Unfortunately, the current quality of our gasoline is still relatively low compared with developed countries, can only be crude. Does not mean we should pay attention to high-grade quality, meaning 97 of the oil does not necessarily impurities than 93 on the low octane grade represent oil, and can not represent the quality and cleanliness.
Vehicle owners in order to ensure cleanliness of gasoline, will add fuel used in gasoline cleaner approach. This can effectively prevent the formation of coke on the metal surface junction layer, and can gradually activated coke particles gradually remove the original, so as to protect the engine from harm. However, the addition of detergent gasoline must be careful, if joined counterfeit products will be the opposite effect.
Second: Do not idle running time.
Idle for a long time the engine reaches normal temperature, it is time for longer, gasoline was sprayed to the valve back on after the slow evaporation rate, carbon deposition is also a result. At the same time often idle, into the engine's air flow also small, so that the erosion of the role of carbon deposition becomes too weak, and will promote the deposition of coke.
Third: Multi-run high-speed, shift to maximize the speed of my hand cars.
Run high-speed multi-purpose is to make use of gas flow on the inlet to prevent the erosion produce coke. In addition, to improve shift speed also has a multi-run high-speed serves the same purpose, the original shift in the rotational speed of 2000 into 2500 when the conversion will not only effective in preventing coke formation, but also can improve the car's power, has also avoided for block caused by detonation speed is too low vibration, protecting the engine.
