How Many Digits Does an Engine Number Typically Have?
1 Answers
Common engine numbers typically range between 7 to 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 when the engine comes off the production line. Some may also include a place-of-origin code. Engine models are identification codes assigned by engine manufacturers in accordance with relevant regulations, corporate or industry practices, and the attributes of the engine. These codes represent information such as the manufacturer, specifications, performance, features, technology, purpose, and batch of the engine, including fuel type, number of cylinders, displacement, and static braking 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 product line, and multiple engines can share the same model. The engine number, however, is a unique production identifier assigned to each individual engine, and no two engines share the same number. Structure of an Engine Number: Prefix: Includes product series codes, generation symbols, and regional or corporate codes. Manufacturers may choose appropriate letters as needed, but these must be approved and recorded by the industry standardization unit. Middle Section: Composed of symbols representing the number of cylinders, cylinder arrangement, stroke, and cylinder diameter. Suffix: Consists of symbols indicating structural and usage characteristics. Tail: Distinguishing symbols. When differentiation is needed due to improvements or other reasons within the same product series, manufacturers may select appropriate symbols. The suffix and tail can be separated by a hyphen (-).
