[VanGarrett]

The chassis number and engine number are usually found on the vehicle's nameplate, the nameplate inside the engine compartment, or the purchase invoice for the engine number; at the lower left end of the front windshield; the factory certificate contains the engine number; the operating license of commercial vehicles can be used to check the engine number; the vehicle purchase tax payment certificate has the engine number; the registration record at the public security authority contains the engine number; the vehicle insurance card has the engine number; the simplest and most direct way to check both numbers is to look at the vehicle registration book or the vehicle's driving license. The engine number is like a person's ID number, representing each vehicle. It stores 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 batch of the engine, including fuel type, number of cylinders, displacement, and static braking power. Engines installed in cars or multi-purpose passenger vehicles are marked with the professional manufacturer's name, model, and production number as required. 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 range, and engine models can be the same. The engine number, however, refers to the production number of the engine, with each engine having a unique number that cannot be duplicated. Composition of the engine number: Front part: 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 filed by the industry standard regulatory body. Middle part: Consists of symbols for the number of cylinders, cylinder arrangement, stroke, and cylinder diameter. Rear part: Comprises symbols for structural features and usage characteristics. Tail part: Distinguishing symbol. When differentiation is needed due to improvements or other reasons within the same series, the manufacturer selects an appropriate symbol, which can be separated from the rear part by a hyphen. Chassis number: Abbreviated as VIN, the Chinese name is Vehicle Identification Number (hereinafter referred to as the chassis number). It is a set of characters assigned by the car manufacturer to identify each vehicle. The chassis number consists of 17 digits and letters, arranged in such a way that no two vehicles of the same model will have the same number within 30 years, ensuring its uniqueness.
