Engine burnt cylinder (how to deal with the failure of the engine combustion chamber?HS code accuracy for automotive exports) The engine is the heart of modern cars and one of the most important parts. Its function is to convert the fuel of the vehicle into mechanical energy to drive the wheels, which is the basis for the normal operation of the car.However, in the process of long-term use, the failure of the engine combustion chamber is a common problem, and it often brings a lot of troubles to the car owner. Next, we will discuss the reasons for the failure of the combustion chamber and how to deal with it. Reason: 1. Heat expansion and cold contraction: After long-term operation, the parts of the engine are affected by temperature changes. There is a cycle of expansion and contraction. In the process, the gap will also widen and cause gas leakage. 2. Mechanical damage: Damage to the valve seat, spark plugs, etc. will basically lead to gas leakage, 3. Oxidative corrosion: During the operation of the engine, it will constantly produce gaside under high temperature and high pressure, resulting in oxidative corrosion of the corners and edges of the components in the combustion chamber. With the growth of time, fine cracks between the parts can be formed, causing leakage problems. Four. Low-speed travelThe conversion of driving and high-speed driving: long-term low-speed driving, the air-fuel ratio is thin, the combustion temperature is reduced, and it is easy to form abnormal combustion at the rear of carbon accumulation, which is easy to cause engine combustion chamber wear or cylinder burning. Response: 1. Maintain good driving habits: During the driving process, pay attention to the use of throttle, brakes and clutches, do not make sharp turns, sudden acceleration, sudden braking, etc., so as to avoid frequent engine shifting and better protect the engine. Two. Regular maintenance: According to the maintenance cycle of the automobile manufacturer, replace the oil, filter and other necessary parts in time, clean the accumulated carbon and other work to prevent oxidation and corrosion, and maintain the normal operation of the engine. 3. Replace damaged parts in time: Check whether the parts of the engine are working normally from time to time. If any problems are found, replace them in time to reduce the possibility of wear or damage.Four. Reasonable use of the vehicle: control the speed of the vehicle to no more than 70 km/h, and try to avoid the frequent start and stop of the vehicle. In the process of exercising the vehicle, you should strengthen the maintenance, regularly maintain spare parts such as the cylinder head, and repair the wear and corrosion in the parts. In a word, the failure of the engine combustion chamber is a common problem in vehicle maintenance. As long as we pay attention to maintenance in daily use, strictly abide by various regulations, find problems as soon as possible and deal with them in time, and regularly maintain and check the condition of the vehicle, we can extend the life of the engine, avoid damage to parts, and maintain the normal operation of the vehicle.
