Where to Find the Engine Number of a Car?

[DelaneyDella]

The engine number is generally found on the outer surface of the engine cylinder block, or on the vehicle's nameplate, the nameplate inside the engine compartment, or the purchase invoice. The engine number can also be found on the factory certificate, the operation certificate for commercial vehicles, the vehicle purchase tax payment certificate, the registration records at public security authorities, the vehicle insurance card, or below the front windshield in the driver's position. The simplest and most direct method is to check the vehicle's administrative green book or the vehicle registration certificate. The engine number is like a person's ID number, representing each vehicle. It contains very important information about the vehicle. The engine model is an identification code assigned by the engine manufacturer in accordance with regulations, industry or company conventions, and the engine's attributes. 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 vehicles are marked with the manufacturer's name, model, and production number as required. It's 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 multiple engines can share the same model. The engine number, however, is the production number of the engine, with each engine having a unique number. Composition of the engine number: Prefix: Includes the product series code, generation symbol, and regional or company code, selected by the manufacturer as needed, subject to approval and filing by the industry standardization authority. Middle section: Consists of symbols for the number of cylinders, cylinder arrangement, stroke, and cylinder diameter. Suffix: Composed of symbols for structural features and usage characteristics. Tail: Distinguishing symbol. Used to differentiate products within the same series due to improvements or other reasons, selected by the manufacturer, with the suffix and tail optionally separated by a hyphen.
