WTO harmonization and HS codes

Engine high-pressure package (Ignition Coil) is WTO harmonization and HS codesan extremely important component in the automobile ignition system. Its main function is to convert low-voltage current into high-voltage current to ignite the mixed gas so that the engine can run normally. The working principle of the engine high-pressure package is very simple, but its function is irreplaceable. Once a problem occurs, it will directly affect the performance, fuel consumption and even safety of the car. In this article, we will discuss the principle, common problems and solutions of engine high-pressure packages to help car enthusiasts and car owners better understand this important component. I. Working principle of engine high-voltage package The engine high-voltage package mainly consists of two parts: one part is a major transformer, and the other part is an electronic component.The main transformer is composed of an iron core and a coil, and the coil is composed of a certain number of laps, a number of wires and a resistivity content. The engine high-voltage package becomes a special AC power supply through the DC power supply, which converts the low-voltage input into high-voltage output at the right time. This output high voltage can be used to ignite the mixture of the gasoline engine. Through the engine electronic control system, the ignition timing of the spark plug and the speed of the engine are controlled. After the engine high-voltage package is turned on, the power supply voltage is input from the battery. After the internal components increase the voltage, the high-voltage current is output to the spark plug, thus forming a strong electric field, igniting the mixed gas and promoting the normal operation of the engine. At the same time, the engine high-pressure package protects the ignition quality of the spark plug with the high-pressure output line, thus prolonging the service life of the spark plug. II. Common problems and solutions of engine high-pressure package 1.Engine jitter or unstable acceleration. When the vehicle cannot accelerate smoothly or evenly, or jitter occurs during acceleration, it may be caused by the failure of the engine high-pressure package. According to experience, this problem is usually caused by the battery or ignition line, such as insufficient battery or corroded power line, which will cause the engine high-voltage package to fail to work properly. If such a problem is found, the connection of the vehicle air filter, spark plug and ignition coil should be checked immediately to determine whether the engine high-pressure package needs to be replaced. Two. Increase in gasoline consumption If your vehicle's fuel consumption "suddenly" increases in a short period of time, it may be due to the failure of the engine high-pressure package. The faulty high-pressure package will reduce the state of the mixed gas, causing the circuit and ignition system to fail, and eventually disrupt the normal exhaust operation of the car engine, resulting in an increase in fuel consumption.You can determine whether it needs to be replaced by checking the engine high-pressure package. 3. If there is a problem with the engine alarm or flashing ignition light in the car engine, it may lead to insufficient battery power or wrong line connection. If there is no problem between the power supply and the line, it may be caused by the failure of the engine high-pressure package. In one case, the high-pressure package has reached the level of complete scrapping. If the OBD system inside the vehicle reports such a problem, you should immediately find professional technicians to diagnose the car to find out the cause of the failure. Four. Unable to start the engine. If it is found that the car cannot start the engine, it is possible that the engine high-pressure package has failed. In this case, the high-pressure package will not provide enough current to ignite the mixed gas. Not only that, at the beginning of the start-up, if it is foundIf the car can't start, the main consideration should be shutters, fuel injectors, spark plugs and other problems, rather than directly suspecting the high-pressure package problem. Because this period is the entry point of the car computer, some high-pressure packages that can finally be used to use the car have performed the work intactly, but cannot be started, so they need to seek management solutions. Conclusion: The importance of the mandatory best of the car engine cannot be ignored, and the engine high-pressure package is an important part of it. When encountering a vehicle failure, it is best to troubleshoot the fault of the high-voltage package first. When there is a problem with the engine high-pressure package, it should be replaced in time to ensure the safety and performance of the vehicle. In order to avoid traffic accidents, you should regularly maintain and inspect the mechanical structure of the vehicle. During vehicle maintenance, it is very important to select professional and technical personnel for diagnosis and maintenance.
