Knowledge Lecture: Analysis of Compilation Rules for Engine Numbers
The engine has two kinds of internal combustion engine and external combustion engine, while the automobile engine uses more internal combustion engines, such as gasoline engine, diesel engine. Its model number is the engine number, and has the same nature as the vehicle identification code (VIN), ie, uniqueness. On the one hand, it is for user traceability; on the other hand, it is for the manufacturer or distributor to follow the survey to obtain feedback. In order to facilitate production management and use, the national GB 725-82 has a clear stipulation on the compilation of automobile engine numbers. The engine number must consist of Arabic numerals and Chinese Pinyin letters. The number is roughly divided into four parts, namely the head, the middle, the back and the tail. The following diagram shows you the meaning of each part of the engine number. Head: For the product series symbol and the replacement logo symbol, the manufacturer selects the corresponding letter according to the need, but the approval of the competent authority is required. Middle: It consists of cylinder number symbol, stroke symbol, cylinder arrangement symbol and cylinder bore symbol. Rear: Structural features and uses Feature symbols, expressed in letters. Tail: distinguish symbols. When the same series of products need to be differentiated due to improvement or other reasons, the manufacturer chooses the appropriate symbol. For example, the common engine model number YC4D130-20 in a special vehicle is expressed as follows: four-cylinder, 108mm bore diameter, 115mm stroke, 130 horsepower, Euro II emission, and basic engine. Finally, Xiao Bian should remind everyone that the engine number of the vehicle must not be tampered with or applied. Otherwise, the change registration will not be handled.
