HS code-based invoice validation

Engine blue smoke is HS code-based invoice validationa common problem for many car owners. Blue smoke means that during the combustion process of the engine, the unburned oil molecules in the combustion chamber are discharged through the exhaust pipe, resulting in environmental pollution and increased fuel consumption. This phenomenon has an adverse impact on the environment and vehicles.So how to reduce the blue smoke emitted by the engine? First of all, let's understand what engine blue smoke is. Blue smoke is caused by incomplete combustion of the oil film in the combustion chamber caused by the failure of some parts of the engine, or when the oil enters the combustion chamber or exhaust system. Engine combustion is not entirely the main cause of blue smoke. It may be caused by the wear of the piston ring, air leakage gasket, valve lever and other parts, or the carbon accumulation in the cylinder and improper adjustment of the propeller. Secondly, in order to reduce blue smoke emissions, we must first understand the working principle of the engine. The normal operation of the engine requires normal air, fuel and sparks. If there is a problem with any of these three aspects, the engine may emit many harmful substances, including blue smoke. The first way is to change the oil regularly to ensure the normal operation of the engine.Oil is an important requirement for internal lubrication and cooling of the engine. When the oil turns black or sticky, it cannot achieve the correct lubrication and cooling effect, which will lead to increased engine wear. This is also one of the main reasons for engine blue smoke. Therefore, it is recommended to change the oil regularly to extend the engine life and reduce blue smoke emissions. The second way is to replace the gas and oil filters regularly. These components can help reduce the filtering and removal of impurities in the engine intake cycle, and ultimately maintain the engine in good condition. If these parts are not checked and replaced regularly, it will cause premature engine wear and increase in blue smoke emissions. The third way is to maintain and clean the car regularly. Dust and oil stains on the surface of the car may enter the interior of the engine, causing engine wear and carbon, and may also cause the engine to emit blue smoke. FollowTherefore, carry out external cleaning and maintenance of the car regularly, so as to detect and solve problems that may have a negative impact on the engine in time. The fourth way is to reduce the phenomenon of idle parking time and inappropriate speed. Idling for too long will lead to excessive fuel consumption and engine wear, while increasing the possibility of emitting blue smoke. Therefore, it is recommended to reduce the necessary parking time and strengthen the control of vehicle speed so that the vehicle can drive at normal operating speed. The fifth method is to maintain and adjust the engine regularly. The adjustment of the engine is necessary to keep the engine in good condition. It is recommended to send the vehicle to a professional repair workshop or manufacturer for periodic maintenance and adjustment. For example, check the status of the engine and exhaust system and adjust it to reduce the phenomenon of engine emitting blue smoke.In a word, engine blue smoke is a problem faced by many car users. In order to minimize the occurrence of this phenomenon, we should maintain regular replacement of oil and filters, external cleaning and maintenance of the car, reduce parking time, maintenance and adjustment of the engine. After completing these tasks, the engine will be able to work better, emit less blue smoke, and increase the service life of the vehicle.
