Comparative HS code duty analysis

Detailed explanation of the causes and Comparative HS code duty analysissolutions of engine oil burning In the process of automobile maintenance, engine oil burning is a relatively common situation. Engine oil burning not only affects the performance of the engine, but also leads to an increase in the loss of engine fuel consumption, which in turn increases the economic burden of the car owner. What is the reason why the engine burns oil?How to solve this problem? This article will give a detailed explanation of these problems. I. The reason why the engine burns oil 1. The piston ring damages the piston ring of the engine. The function of the piston ring is to maintain the gap between the piston and the cylinder and ensure the flow of oil between the piston and the cylinder. When the piston ring is damaged, deformed, aging and other conditions occur, the sealing of the piston and cylinder is affected, causing the oil to enter the combustion chamber and burn out, resulting in oil loss. Two. The smoothness and roughness of the cylinder wall gradually increase due to wear or deformation caused by high temperature, resulting in a decrease in the fluidity of the oil between the cylinder and the piston. When the piston moves up and down, the oil will stay around the cylinder to form carbon, which increases the possibility of oil burning in the combustion chamber. 3. Under the oil san shell is worn under the oil sin shellIt is equipped with pistons and cylinders. When the engine is in normal operation, the piston will move repeatedly, which is bound to have a violent impact on the oil san. When the engine is worn or aged, the sealing of the oil san shell will have problems, causing the oil to enter the combustion chamber. In this case, it is usually necessary to replace the oil san to solve the problem. Four. The valve duct is damaged. The valve duct is a channel in the engine, connecting the air intake and the cylinder. If this channel is damaged or there is a problem, the oil will be inadvertently sucked into the cylinder and then burn. This situation seems difficult to detect, but if it is found that the fuel consumption loss is more than usual, this possibility should be considered. 5. Lubrication system failure The lubrication system is a key part necessary for the normal operation of the engine, and it also plays a decisive role in the oil consumption in the engine combustion chamber.If there is a problem with the lubrication system, the oil may enter the environment. In this case, it is usually necessary to check the lubrication system and its related materials and components to maintain its integrity and normal operation. II. Solution 1. Frequent oil change If you witness the engine consume oil during frequent operation, you can consider changing the oil frequently to make up for the lack of oil. Frequent oil replacement will slow down the incidence of engine oil burning and improve the operating life of the engine. Two. Timely maintenance of the piston ring. When a problem with the piston ring is found, the piston ring should be maintained and replaced as soon as possible. Replacing the piston ring will effectively alleviate the situation of engine oil burning and avoid oil waste and additional economic expenditure caused by it. 3. Using reliable quality oil to replace the oil is not the final solution. Using high-quality oilIt can slow down the combustion rate of the oil, improve the viscosity and fluidity of the oil, and protect the sealing performance of the engine and improve the output power of the engine. Four. Regular car maintenance is very necessary to prevent the incidence of engine oil burning, extend the service life of cars and improve car safety. Regular car maintenance is very necessary. Proper maintenance can keep the engine in good condition and prevent problems from spreading to the whole system or other parts. In summary, engine oil burning has a significant impact on the performance and service life of the vehicle. In order to avoid this phenomenon, the owner needs to make careful and serious adjustments to the engine of the vehicle, strictly control the oil replacement and maintenance cycle, and use reliable quality oil and replace defective parts in time. Diagnose oil consumption as soon as possibleAdditional problems, actively adopt the right method to control its continued development, so that you can ensure the prerequisites for safety and durability.
