How Many Digits is an Engine Number?
1 Answers
The common engine number is generally between 7-8 digits. The sequence and content of the engine number may vary among different manufacturers. It usually includes the engine model, production date, and a randomly assigned serial number given when the engine comes off the production line. Some may also include a place-of-origin code. Engine model is an identification code assigned by the engine manufacturer in accordance with relevant regulations, corporate or industry practices, and engine attributes for a batch of identical products. It represents 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, among others. 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 multiple engines can share the same model. The engine number, however, refers to the production number of the engine, which is unique to each individual engine. Composition of a Vehicle Engine Number: Prefix: Includes product series code, generation symbol, and regional or corporate code. Manufacturers may choose the corresponding letters as needed, but they must be approved and filed 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. When differentiation is required due to improvements or other reasons within the same product series, the manufacturer may choose an appropriate symbol to represent it. The suffix and tail may be separated by a hyphen.
