The engine number of the BAIC BJ80 is located on the left side of the engine block, near the left front wheel. In addition to the above method, the engine number can also be checked through the following four ways: The vehicle's driving license contains the engine number, usually located in the second-to-last line; The motor vehicle registration certificate will indicate the engine number; The car purchase invoice will specify the engine number; The vehicle purchase tax payment certificate will indicate the engine 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 range, and engine models can be the same. The engine number refers to the production number of the engine, where each engine can only have one unique engine number, and no two engines share the same number. The engine number consists of four parts, each representing different meanings. The first part includes the product series code, generation symbol, and regional or enterprise code, which are selected by the manufacturer as needed but must be approved and filed by the industry standard regulatory body. The middle part consists of symbols for the number of cylinders, cylinder arrangement, stroke, and cylinder diameter. The rear part includes symbols for structural features and usage characteristics. The tail part is a distinguishing symbol, used by the manufacturer to differentiate between products in the same series due to improvements or other reasons.
