How Many Digits Does a Car 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 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 production location 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, processes, purpose, and batch of the engine, including fuel type, number of cylinders, displacement, and static brake power. 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 range, and the same model can be used for multiple engines. The engine number, however, refers to the production number of the engine, and each engine can only have one unique engine number, with no two engines sharing the same number. Composition of a car engine number: Front section: Includes product series code, generation symbol, and regional or corporate code. Manufacturers may choose the appropriate letters as needed, but these must be approved and filed by the industry standard regulatory body. Middle section: Consists of symbols for the number of cylinders, cylinder arrangement, stroke, and bore diameter. Rear section: Comprises symbols for structural features and usage characteristics. Tail section: Differentiation 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. The rear and tail sections may be separated by a hyphen (-).
