[MacJade]

The engine number of an A6 is located on the lower left side of the engine, near the flywheel. 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, manufacturing process, intended use, and production batch of the engine, including fuel type, number of cylinders, displacement, and static braking power. 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, manufacturing process, intended use, and production batch of the engine, including 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, 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, on the other hand, refers to the production serial number of the engine, which is unique to each individual engine. Composition of the vehicle 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 authority. Middle section: Consists of symbols for the number of cylinders, cylinder arrangement, stroke, and cylinder diameter. Suffix: Composed of symbols for structural features and intended use. Tail: Distinguishing symbols. When differentiation is required due to improvements or other reasons within the same product series, manufacturers may select appropriate symbols. The suffix and tail may be separated by a hyphen (-).
