For example, when purchasing electrical parts, check whether the voltage and power of the replaced parts are consistent. When purchasing the transmission belt, pay attention to whether the model and circumference are consistent. When purchasing the fuel injection head, pay attention to the diameter of the nozzle and the angle of the atomizing cone. Whether it is accurate; when purchasing pistons and piston rings, it should be distinguished whether it is standard or enlarged.

The package name and box should be marked with the product name, specification, model, quantity, registered trademark, factory name and telephone number. Some large or important parts are also equipped with instructions for use, certificate of conformity and seal of inspector when they are shipped. They should be recognized when purchasing, so as to avoid the purchase of counterfeit and shoddy products.
