Where Can the Engine Number of a Vehicle Be Found?

[CooperLynn]

Locating the engine number: The engine number can be found on the outer surface of the engine block, the vehicle's registration certificate, the motor vehicle registration certificate, the purchase invoice, the factory certificate of compliance, the operation certificate for commercial vehicles, the vehicle purchase tax payment certificate, public security authority registration records, the vehicle insurance card, the B-pillar nameplate of the motor vehicle, and the actual engine (usually on the engine nameplate). The engine number, much like a person's ID number, represents each vehicle and contains very important information about the vehicle. 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, for a batch of identical products. It indicates information such as the manufacturer, specifications, performance, features, technology, purpose, and production batch of the engine, including fuel type, number of cylinders, displacement, and static braking power. Engines installed in passenger cars or multi-purpose passenger vehicles are required to display the professional manufacturer's name, model, and production number. 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 identical. The engine number, however, refers to the production number of the engine, where each engine has a unique number that cannot be duplicated. Composition of the vehicle engine number: Front section: Includes the product series code, generation symbol, and regional or corporate code, which are selected by the manufacturer as needed and must be approved and recorded by the industry standard authority. Middle section: Consists of symbols representing the number of cylinders, cylinder arrangement, stroke, and cylinder diameter. Rear section: Comprises symbols indicating structural features and usage characteristics. End section: Differentiation symbol. When differentiation is required due to improvements or other reasons within the same product series, the manufacturer selects an appropriate symbol to denote this, with the rear and end sections potentially separated by a hyphen.
