What Does the Number of Digits in an Engine Number Mean?
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. The engine model is an identification code assigned by the engine manufacturer in accordance with relevant regulations, industry or company practices, and the attributes of the engine. It represents information such as the manufacturer, specifications, performance, characteristics, technology, purpose, and production batch of the engine, including details like fuel type, number of cylinders, displacement, and static braking power. Engines installed in passenger cars or multi-purpose 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, where each engine has a unique number that cannot be duplicated. Composition of a Vehicle Engine Number: Front Section: Includes product series codes, generation symbols, and regional or company codes. Manufacturers may choose appropriate letters as needed, but these must be approved and recorded by the industry standard regulatory body. Middle Section: Consists of symbols for the number of cylinders, cylinder arrangement, stroke, and cylinder diameter. Rear Section: Comprises symbols for structural features and usage characteristics. Tail Section: Differentiation symbols. When differentiation is required due to improvements or other reasons within the same product series, manufacturers may select appropriate symbols. The rear and tail sections can be separated by a hyphen (-).
