HS code-based invoice matching

Engine circuit diagram (reconstruction engine circuit diagram: concise version!) The HS code-based invoice matchingcircuit diagram of modern automobile engines is usually a complex figure composed of countless lines and components. If you are not an automotive electrical expert, you may not be able to understand the role and interrelationship of each part of it. However, for those who need to repair or maintain their cars, it is very important to have an in-depth understanding of the engine circuit diagram.If you find your own car engine circuit diagram and reconstruct it into a more concise and easy-to-understand form, it will be a very useful job. In the following, we will show how to simplify the engine circuit diagram so that it is easier to read and understand. Step 1: To better understand the engine circuit diagram, we need to familiarize ourselves with the meaning of some commonly used symbols and lines. The following are the meanings of some common symbols: - Battery symbol: indicates the battery (or many batteries), usually representing the circuit part powered by the battery. - Ground wire symbol: indicates the ground or ground wire, which usually represents the circuit part placed on the ground. - Wire symbol: indicates the path and connection of the wire. The main circuit is represented by a solid line and the auxiliary circuit is represented by a dotted line. - Switch symbol: indicates a component that can turn on or off the circuit.Usually, wires are used to represent unopened circuits, and graphics between wires are used to represent open circuits. - Electrical symbols: indicating electrical devices, such as light bulbs, motors, engines, fans, etc. It is usually represented by a circle. After familiarizing with these basic symbols, we can start to check the engine circuit diagram and begin to reconstruct. Step 2: The graded structured and complete engine circuit diagram will include many lines and components, and its structure is very complex. When reconstructing the engine circuit diagram, you can simplify the circuit diagram by grading and structuring it. This can be achieved by forming a hierarchical structure in the circuit diagram. For example, you can first identify and mark the main power line directly related to the battery. Next, you can add components connected to the line, such as generators, starters, circuit fuses and regulators. Step 3: Simplify the line. The next step is to simplify the line.There are a large number of lines across the circuit diagram, and we usually only need to pay attention to the main components and lines. Therefore, we can first consider bolding the main line to indicate the key area. After that, you can consider starting to delete the secondary lines to reduce the complexity of the circuit diagram. However, the cut line should also be edited in the correct area. Determining the necessary lines is the step before deleting the secondary lines, not blindly deleting them. Because small lines may play an important role in the whole circuit. Therefore, we should make sure to understand the role and connectivity of each line before considering deletion. Step 4: Color and description In order to better understand the engine circuit diagram, we can use different colors or descriptions to distinguish different lines or components. For example, we can use special colors to represent the main power line, auxiliary circuit, fuse, electronic components, etc.At the same time, using annotations or explanatory text can also help us better organize and understand the circuit diagram. In summary, through these steps, we can transform the complex and chaotic engine circuit diagram into a clearer and more concise form. When reconstructing the engine circuit diagram, it is necessary to fully understand each circuit symbol and component, and present it to the reader in a clearer way in layers and boldness. When cutting some lines, it is necessary to ensure that the function and connectivity of each line are fully understood, and do not delete any lines at will. Finally, by using colors or annotations to clarify and annotate, it can help us better organize and understand the circuit diagram.
