In the field of automobile maintenance, the problem of engine carbon deposition has always been the focus of attention of the majority of car owners. As the heart of the car, the efficiency and life of the engine are closely related to the cleanliness of the engine. This article will discuss the formation of carbon deposits, hazards, and the importance of cleaning, so as to reveal the necessity of engine carbon deposits.
1. The formation process of carbon deposition and **.
Engine carbon deposition is a solid substance formed after incomplete fuel combustion or oxidation and polymerization of engine oil vapor in a high-temperature environment, which is mainly distributed in key parts such as intake manifolds, valves, combustion chambers, and fuel injectors. Reasons for this include:
The fuel quality is not high, there are more impurities in gasoline, and a large amount of unburned deposits are produced during combustion.
Long-term short-distance driving, the engine can not be fully preheated, and the fuel can not be fully atomized and burned.
In the cold start stage, the mixed oil and gas are too concentrated, and some of the unburned oil and gas adhere to the inner wall of the engine.
As the oil ages, the sludge produced by evaporation enters the combustion chamber to participate in combustion.
Second, the hazards of carbon deposits.
Affect power performance: Carbon deposition will clog the fuel injector, resulting in poor fuel injection and reduced fuel atomization effect, which in turn affects the quality of the mixture and reduces the power output and fuel economy of the engine.
Increased risk of wear: Carbon deposits accumulate in valves, piston rings, etc., which can affect the tightness between components, which can lead to problems such as air leakage, oil burning, and exacerbate mechanical wear inside the engine.
Cause the fault warning light to light up: Excessive carbon deposition may cause the engine management system (EMS) to misjudge, resulting in fault light alarms, such as EPC, OBD and other system prompts.
Exacerbate emission pollution: The presence of carbon deposits will interfere with the normal operation of the exhaust gas treatment system, increase harmful gas emissions, and cause adverse effects on the environment.
3. The necessity and method of engine carbon deposition cleaning.
Necessity: Regular engine carbon deposition cleaning helps to keep the engine interior clean, reduce various problems caused by carbon deposition, improve the work efficiency of the engine, prolong the service life, and also help reduce environmental pollution.
Cleaning method: chemical cleaning method: by adding a special engine carbon deposition cleaning agent, the carbon deposition is dissolved and discharged during the engine operation.
Mechanical cleaning method: professional equipment is used for dismantling and cleaning, which is suitable for serious carbon deposition, but the operating cost is high and the technical requirements are strict.
Regular maintenance: Use high-quality fuel and oil, avoid long-term idling or short-distance low-speed driving, and properly drive at high speeds and long distances to help prevent carbon deposits.
Summary. In summary, engine carbon cleaning is a very necessary maintenance measure. In the face of various potential hazards caused by carbon deposits, car owners should choose appropriate cleaning methods according to the actual situation of the vehicle, and regularly remove carbon deposits to ensure that the engine is always in good running condition, so as to achieve the purpose of protecting the car, saving fuel, reducing emissions, and improving the driving experience.
