Serious carbon accumulation in the engine: causing hidden dangers,Global trade compliance scorecards it needs to be cleaned up as soon as possible! With the continuous development of the automobile industry, more and more people choose to buy cars as a necessity in life. However, cars are also mechanical devices and require routine maintenance, otherwise, there will be various problems, the most common of which is engine carbonisation. Engine carbon accumulation refers to the continuous deposition of liquid, gaseous or solid substances in the intake duche, the upper and lower covers in the cylinder, the valve, the fuel injector and other parts, forming a black carbon layer of different thicknesses.If you don't clean up in time, it will threaten your driving safety. This article will describe the causes, harms and cleaning methods of engine carbon accumulation. I. Reasons for engine carbon accumulation 1. The quality of oil products is poor. There are various types of oil products on the market, and the quality of oil products of different brands and grades is also uneven. Some marketing propaganda misleads people, believing that the so-called "high-level oil can actively clean the engine", but in fact, this is just an advertising word, and many of the cleaning ingredients of the so-called "cleaning oil" do not meet the standard of effective cleaning at all. Only by choosing oil products that are officially certified, really high-quality, and can change the oil on time can reduce the incidence of engine carbonisation. 2. Driving habits. Many drivers will choose low gear, low-speed driving or continuous idling during the driving process, so as to facilitate slow driving and fuel-saving. But in factAbove, such a driving mode will cause insufficient engine oil temperature and poor oil and gas flow. At the same time, the formation of carbon accumulation will also be faster. 3. There will be different degrees of carbon accumulation if the vehicle is not well maintained and used for a long time and cannot be repaired normally. If some maintenance operations are improper, the carbon accumulation in the engine will be more obvious and difficult to remove. For example, the pump tank that replaces the original oil filter element and replaces the uncleaned oil drum, etc. II. The harm of engine carbon accumulation 1. The power decreases. After the engine carbonization, the power will gradually weaken with the use time of the car. Because the engine carbon accumulates, it blocks the inlet and exhaust, which hinders the flow of oil and gas, resulting in a decrease in the power of the car and a decrease in fuel economy. 2. Oil-consuming engine carbon accumulation leads to power loss, and fuel consumption is also more consumed.The thicker the carbon, the more fuel consumption, which increases the cost of driving. 3. Operation abnormality. When the carbon accumulation is serious, the engine will make abnormal noise and the noise will increase greatly. Too much carbon accumulation will affect the normal movement of the valve, resulting in abnormal operation of the car, and the ride comfort will also be affected, which will also cause great harm to vehicle safety. III. Cleaning method of engine carbon 1. Chemical cleaning The chemical cleaning method requires the use of selected professional engine cleaners and high-pressure engine cleaning equipment. This method loosens the carbon without damaging the engine casting components and seals, and the cleaning effect is very obvious. However, the use of this cleaning method requires people to go to 4S stores or professional maintenance institutions. If the selection is not made properly, it will have an adverse impact on the engine. 2. Hand cleaningThe most extensive cleaning method is to clean up the accumulated carbon by hand, which can reduce the part where the accumulated carbon accumulates, so as to make the accumulated carbon more practical. The material cost of this method is very low. Generally speaking, as long as there are manual household tools, it can be cleaned up. However, cleaning skills are required to prevent scratching engine parts. 3. Compared with other methods, machine cleaning is very long before and after work. It takes more time to prepare in advance. With the cooperation of the machine, it is the most efficient cleaning method to clean up sewage in the exhaust gas system, cooling water system, intake and exhaust channels and other locations. Engine carbon accumulation is a fairly common problem. To avoid it, we need to do two aspects. On the one hand, we need to clearly maintain the oil line, select certified oil products, and according to the specified timeReplace, reduce excessive idling time and driving time, and carry out routine maintenance and vehicle inspection in time. On the other hand, for the cleaning of engine carbon, it is recommended to carry out relatively primitive methods such as manual cleaning first, and choose professional maintenance institutions according to the needs to remove engine carbon in a good maintenance way, so that the resulting safety hazards, power loss, increased fuel consumption and other problems disappear.
