How to evaluate supplier reliability

Engine number picture interpretation,How to evaluate supplier reliability revealing the secret of the car Engine number, as one of the important symbols of a car, is engraved on the car engine and vehicle driving license. However, for most car owners, the engine number does not mean much. It is more about its license plate number and vehicle practicality, and does not know much about the performance and secrets of the engine. And it is from the beginning of the engine number that we may be able to reveal many secrets of cars. I. The function of the engine number. The engine number is after the owner buys the car.Quickly determine the engine model, production batch, origin, production date and other information marks of the purchased vehicle. Nowadays, more and more vehicles are produced and sold, and the production process of vehicles is becoming more and more complex, and the importance of engine numbers is more prominent. II. The interpretation of the engine number The engine number usually includes multiple letters and numbers. Although it seems irregular, in fact, the relevant information of the engine can be interpreted through the meaning of different characters. Here, we take a common engine number as an example to interpret it. 1. The first three digits of the engine number in the manufacturer's area usually represent the manufacturer's area. As shown in the figure, this position is "ZFA". For example, ZFA is the engine code prefix of Fiat Automobile Company in Italy. Two. The fourth digit of the engine number in the reserved area is mostly reserved characters.There is no special meaning of referring, but after a period of time, the manufacturer will use it to distinguish different models, and continue to retain and explain accordingly in the future. 3. The fifth to ninth digits of the engine type and displacement area engine number are the engine model area, of which the fifth to seventh digits usually represent the engine type, and the eighth to ninth digits mostly refer to the engine displacement. Take the sample as an example, the fifth to seventh digits "007" represent a series of models of the Fidick engine, while the eighth and ninth digits represent the engine displacement, which is 1.4 liters. Four. The tenth to fourteenth digits of the engine number in the inspection area are usually the engine inspection number, which is used to confirm the inspection record of the engine for quality management during production. III. The secret hidden behind the engine number is for professionals in some industries, by launchingThe machine number can learn more about the technical details and manufacturing process of the car, such as the manufacturer, whether the model meets the standard, whether there are defects and other issues. For some ordinary car owners, the technical details implicit in the engine number are not so clear. Taking the sample again as an example, we can reveal more secrets of the car from the information revealed by the engine number. 1. Manufacturers and countries take sample engines as an example. The meaning of ZFA refers to Italy and France, which also means that their engines are produced in these two countries, and the degree of completion is unknown. After all, the engines produced and manufactured by Fiat in different regions may be different. Two. The engine type and displacement are as mentioned above. The engine model in the sample is "007", which represents the specific guard series of Ferdick. And the displacement of 1.4 liters representsThe size of the engine, the larger the number, the larger the volume of the engine, which generally means that the engine has better power. 3. Engine quality The engine number can not only confirm the production information of the car, but also hide the clues of the car problem. For example, some car owners can confirm whether there is a quality problem with the car by using the engine number when buying a used car. Because the engine number can reflect the production date of the car, if the used car purchased is too long, its engine may have been used for a period of time, and there may be quality hazards. In general, although the engine number is just a string of seemingly obscure codes, it contains many details of the production process of automobile manufacturers. Although it is difficult for ordinary car owners to understand the technical details implicit in the engine number, it is still helpful to understand this information when buying a car to improve the safety and reliability of the car.In addition, when buying a used car, it is also very necessary to master the skill of interpreting the engine number, which can reduce the risk of buying a car and economic losses.
