How many digits is a car engine number?
1 Answers
Common engine numbers typically range between 7-8 digits. The sequence and content of the engine number can vary among different manufacturers. Generally, it 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 location code. Engine model is an identification code assigned by the engine manufacturer in accordance with relevant regulations, company 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, where each engine is assigned a unique number that differs from all others. Structure of a car engine number: Front section: Includes product series code, generation symbol, and regional or company code. Manufacturers may choose appropriate letters as needed, but these must be approved and recorded by the industry standardization unit. Middle section: Consists of symbols representing the number of cylinders, cylinder arrangement, stroke, and cylinder diameter. Rear section: Composed of symbols indicating structural features and usage characteristics. Tail section: Distinguishing symbol. When differentiation is needed within the same product series due to improvements or other reasons, manufacturers may choose appropriate symbols. The rear and tail sections can be separated by a hyphen (-).
