Where to Find the Vehicle Engine Number?

[LaAdaline]

Locating the engine model number: It 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, the public security authority registration record, the vehicle insurance card, the B-pillar nameplate of the motor vehicle, and the actual engine (usually on the engine nameplate). The engine number, like a person's ID number, represents each vehicle and stores crucial information about it. 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 the manufacturer, specifications, performance, features, technology, purpose, and production batch of the engine, such as 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 lineup, and multiple engines can share the same model. The engine number, however, refers to the production serial number of the engine, with each engine having a unique number. Composition of the vehicle engine number: Prefix: Includes the product series code, generation symbol, and regional or corporate code. Manufacturers may choose appropriate letters as needed, but these must be approved and recorded by the industry standard authority. Middle section: Consists of symbols for the number of cylinders, cylinder arrangement, stroke, and cylinder diameter. Suffix: Comprises symbols for structural features and usage characteristics. Tail: Distinguishing symbol. When differentiation is needed due to improvements or other reasons within the same product series, manufacturers may select appropriate symbols. The suffix and tail can be separated by a hyphen.
