As the saying goes, the details determine the success or failure, but the authenticity is a fatal injury. As we all know, the car is a high-speed moving object composed of a variety of spare parts, so the quality of the spare parts will directly affect the performance and life of the vehicle, and even related to driving The safety of the occupants. However, it is strongly reminded that the spare parts market is chaotic and the existence of counterfeit parts not only disturbs the car environment, but also brings hidden dangers to the safety of the car. Therefore, it is necessary to learn to identify and Have a pair of eyes.
Some people ask, from the appearance of fake and shoddy spare parts, it can almost be fake, can be analyzed to see its internal, but it is very different. So how to identify? Today, take the pure oil filter as an example, analyze the gadgets The big features, as well as the advantages of real parts and the dangers of counterfeit and shoddy parts.
As we all know, the filter is located in the lubrication system of the engine. The upstream of the filter is the oil pump, and the downstream is the parts that need lubrication in the engine. The function of the filter is to filter out harmful impurities from the oil from the oil pan. Clean oil is supplied to the crankshaft, connecting rod, camshaft, supercharger, piston ring and other motion pairs to lubricate, cool and clean, so as to avoid damage to various components, thus extending the service life of these components. What kind of mystery is hidden inside the similar true and false machine filter?
First of all, the pure oil filter housing is filled with high-density filter paper, which has a large filtering area, good effect and high efficiency. It has a special bypass valve inside, which can ensure that the filter element can also be organic oil in the blocked state. supply.
Second, the complex anti-flow design ensures that the machine has the necessary oil for the next start-up, reducing the wear of the engine during cold start. O-ring design, high-quality rubber material, high temperature resistance, good sealing performance, no seepage Oil, to ensure safe use. The number of meshes in metal oil mesh, the interval is strictly in line with the standard specifications of pure spare parts, to ensure the oil quantity.
Thirdly, from the appearance of the counterfeit and fake oil filter, the workmanship is rough, the choice of filter paper is not in line with the norm, and the internal substantive production is to cut corners. With such a counterfeit filter, there is no filtering effect at all, which easily leads to the engine. Wear. The filter is easily clogged during use, causing engine damage or even scrapping. If the oil returns, it will cause damage to the engine when it is restarted. It will also cause oil leakage to cause terrible fire.
Then, there are many counterfeit and shoddy parts in the market. Once the use will cause safety hazards, how can we guarantee the use of genuine accessories? It is recommended that you choose a regular storefront, and do not replace it at the roadside store because of cheapness. In short, wipe Bright eyes, raising vigilance is the right way.
