How Many Digits Does an Engine Number Have?
1 Answers
The common engine number generally consists of 7-8 digits. The sequence and content of the engine number may vary depending on the manufacturer. It usually includes the engine model, production date, and a randomly assigned serial number when the engine comes off the production line. Some may also include a location code. 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. It is used to represent 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, 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. 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 a Vehicle Engine Number: Front Section: Includes the product series code, generation symbol, and regional or corporate code, which are 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 bore diameter. Rear Section: Comprises symbols for structural features and intended use. Tail Section: 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 indicate this, with the rear and tail sections potentially separated by a hyphen (-).
