How Many Digits is the Engine Number?
1 Answers
Common engine numbers typically range between 7-8 digits. The sequencing and content of engine numbers may vary among different manufacturers. Generally, they include 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. It is used to represent information such as the manufacturer, specifications, performance, characteristics, technology, purpose, and production batch of the engine, including fuel type, number of cylinders, displacement, and static brake power, among others. Engines installed in passenger cars or multi-purpose passenger vehicles are required to display the professional manufacturer, model, and production number of the engine. 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. On the other hand, the engine number is the production number of the engine, with each engine having a unique number that cannot be duplicated. Composition of a Vehicle Engine Number: Front Section: Includes product series code, generation symbol, and local or corporate code. Manufacturers may choose appropriate letters as needed, but these must be approved and filed with the industry standard regulatory body. Middle Section: Consists of symbols for the number of cylinders, cylinder arrangement type, stroke, and cylinder diameter. Rear Section: Composed of symbols for structural features and usage characteristics. Tail Section: Distinguishing symbol. When differentiation is needed due to improvements or other reasons within the same product series, manufacturers may select appropriate symbols for representation. The rear and tail sections can be separated by a hyphen (-).
