The accessories in the car market can be said to be a mixture of good and bad people. Some fake accessories are real, making the people of the car country "miserable". Last Saturday and Sunday, the second of the March 15 service class,'Fiery Eyes 'Identifying Real and False Accessories ", started. It told the story of" Tang Priest "identifying real and false accessories on the way west to retrieve the true car scriptures.

Original gasoline filter parts and counterfeit parts

"Eyes on Fire": According to Zhang Junming, the gasoline filter filters and protects the gasoline after it enters the gasoline pump, so that the system can work normally. Counterfeit gasoline filters have poor filtering effect, which can easily block oil nozzles, etc., and the air burns with engine oil without being filtered, which will cause cylinder pulling and reduce injection pressure, resulting in insufficient power, increased fuel,fuel consumptionIf it rises, it will seriously burn the gasoline pump and require major repairs. When identifying, there are marks on the original parts, such as part number, manufacturer code and country of production code, cutting head and head, but no counterfeit parts. Secondly, the cross-section of the counterfeit parts looks very flat and the workmanship is rough, while the original parts have a concave and convex feeling.

Original brake pad parts and counterfeit parts

"Eyes on fire": Brake pads are related to car safety and are of great importance. Zhang Junming said: Once the brake pads are not good, they will be easy to take off, the brakes will not work well, and they will be easy to come off during use. Normal brake pads have a long service life, generally capable of being used for 40,000 - 50,000 kilometers. In terms of identification, there are labels on the packaging of the original parts, there are cut surfaces on the brake pads, and the counterfeit parts are arc-shaped. The surface of the counterfeit parts has pits and bright spots, which is uneven, which will easily cause eating, while the original parts are very smooth.

Original headlight parts and counterfeit parts

"Fiery Eyes": In the judgment and identification of headlights, Zhang Junming taught everyone the skill: look at the oxidation degree of the headlights. The thickness of original parts is thick, while the thickness of counterfeit parts is thin. Open the back cover of the lamp, the surface of the original parts is flat, and the surface of the counterfeit parts is rough. In addition, judging from the exterior sign, it is not difficult to find that the original part sign is clear, and the "lion" is located directly above the English VALEO. The counterfeit sign is vague, and the "lion" is located on the left side of the English VALEO.

Original and counterfeit parts of shock absorber

"Eyes on Fire": When buying shock absorbers, friends can carefully review the packaging and trademarks. Secondly, it can be found that the shock absorber of the original parts has direction labels attached to it, but the counterfeit products do not. In addition, if you look closely at the key parts of the shock absorber as shown in the figure, you will find that the original parts are welded, while the counterfeit parts are crimped. There are deformation holes on the original parts, but there are no deformation holes on the counterfeit parts.

"Oil filter elements and air filter elements, as accessories that need to be replaced at 5000 kilometers and 10000 kilometers, should be placed first. If you replace it with a poor quality one when replacing it, it will easily cause 'internal injuries' to the car." Therefore, when Manager Zhang "prepares lessons", he listed both of these as the focus of this class.

oil filter element

"Eyes on Fire": There are three main methods to identify engine oil filters: "Looking at the paint surface, the surface of the engine oil filter produced by the main factory is matt paint, which has a texture. The surface of the engine oil filter produced by the auxiliary factory is made of ordinary paint. Although it is brighter, it lacks texture."

"Second, look at the factory logo. For example, the one produced by Geely has the Geely logo on it, and the logo of the auxiliary factory is just a marginal ball, making people think it is Geely at first glance. When you look carefully, one of the letters has been revised. It was removed in an attempt to muddle through. Third, look at the printing fonts. The printing in the auxiliary factory is relatively rough, and the words in the main factory are clearer."

Manager Zhang also said that the current production technology of fake parts can be said to be advancing by leaps and bounds, with almost 100% similarity in appearance and details. Therefore, it can often be seen as fake parts, but "the internal structure is quite different, so this cannot be deceived."

Manager Zhang finally provided a good solution,"If you look at it carefully, the parts of the main factory have clear texture, good paper material, and uniform density. The parts of the auxiliary factory have relatively short lengths, few folds, and poor paper quality. This will lead to The resistance to pressure is poor and the oil is not good. After passing through oil bubbles, it is easy to deform and rot, and the oil will be sucked into the engine, causing the lubrication oil to be blocked."

air filter

"Golden Eyes": The two air filter elements on display are made of the same white material and have the same folds, making it difficult to distinguish whether they are real or fake.

Manager Zhang also believes that this identification is quite difficult: "There is no absolute standard for identification. The parts of the main factory are thin and light to the hand, because the manufacturer uses silk materials, which are relatively uniform, so that the air passage rate is high. The ones from the auxiliary factory are thicker and heavier, because the materials they use are not good and cannot achieve the effect of the original factory, so they have to thicker a few layers. Therefore, everyone focuses on the density."
