What Does the Car Number Mean?

[McCorbin]

Car number, also known as engine number, consists of four main parts. It serves to facilitate the production management and usage of engines, and is an identification code assigned by engine manufacturers to a batch of identical products in accordance with relevant regulations, corporate or industry practices, and engine attributes. The specific meanings are as follows: 1. The prefix includes product series code, generation symbol, and regional or corporate code. Manufacturers can choose corresponding letters as needed, but these must be approved and filed by the industry standard regulatory body. 2. The middle part consists of symbols for the number of cylinders, cylinder arrangement type, stroke, and cylinder diameter. 3. The rear part includes symbols for structural features and usage characteristics. 4. The suffix is a distinguishing symbol. When differentiation is needed due to improvements or other reasons within the same product series, manufacturers may select appropriate symbols to indicate this, with the rear part and suffix separated by a "-".
