Where is the engine number located?

[McJayce]

The engine number is generally found on the outer surface of the engine block, or on the vehicle's nameplate or the nameplate inside the engine compartment. The simplest and most direct method is to check the vehicle's administrative green book or the vehicle registration certificate. The engine number, like a person's ID number, represents each vehicle and contains very important information about the car. The engine model is an identification code assigned by the engine manufacturer in accordance with relevant regulations, corporate or industry practices, and the attributes of the engine. It is used to indicate information such as the manufacturer, specifications, performance, characteristics, technology, purpose, and production batch of the engine, including fuel type, number of cylinders, displacement, and static braking power, among others. Engines installed in passenger cars or multi-purpose passenger vehicles are all marked with the professional manufacturer, model, and production number as required by regulations. It is important to note that the engine number is not the same as the engine model. The engine model refers to the specifications and size of the engine within the manufacturer's product line, and engine models can be the same. The engine number, however, refers to the production number of the engine. Each engine can only have one engine number, and the number for each engine is unique. Composition of the vehicle engine number: Prefix: Includes product series code, generation symbol, and regional or corporate code. Manufacturers can choose the corresponding letters as needed, but they must be approved and filed by the industry standard standardization unit. Middle section: Consists of the cylinder count symbol, cylinder arrangement symbol, stroke symbol, and cylinder diameter symbol. Suffix: Composed of structural feature symbols and usage feature symbols. Tail: Distinguishing symbol. When differentiation is needed within the same product series due to improvements or other reasons, the manufacturer selects an appropriate symbol for representation. The suffix and tail can be separated by a hyphen (-).
