Usually we blow water, most of them pay attention to the main engine factory, model products, and rarely pay attention to the aftermarket, such as tires, brake pads, lubricating oil and so on. Now these things are a variety of categories, fish and dragons, uneven quality, recently the State Administration of Market Supervision announced the quality of road traffic products in 2021 spot checks, such as Izumi, 3M, Total and other well-known products have been shot.
Brother Man borrowed flowers to offer Buddha, and used them to interpret them to avoid thunder for everyone.
First of all, the Municipal Supervision Commission inspected a total of 1336 enterprises with a total of 1342 batches of products, including automotive brake linings, brake tubes, tires, seat belts, external lights, brake fluids, engine lubricants, gasoline detergents, etc., and the result was a random inspection failure rate of 13.9%.
Brake linings
The brake liner is not a brake pad, the liner is a friction brake material on the back plate of the brake pad, which is specially used on the rear drum brake.
The municipal supervisor greatly inspected 120 batches of products, and only 3 batches of products were unqualified, and the unqualified rate was 2.5%, mainly due to the excessive harmful elements and unqualified friction performance. The production units of unqualified products are Jiangsu Jinmaisui New Energy Technology, Zhejiang Flex Le Friction Materials, and Shandong Liangshan Guanliang Auto Parts.
Brake ducts
That is, the brake hose, which is used to transmit liquids, gases and other media in the car brake, so that the car brake produces braking force.
This kind of parts and components products basically have no brand to speak of, and they are all what the auto repair plant is used for. However, judging from the unqualified rate of 3.7% in the spot check results, the quality is not too worrying.
tyre
There are not many batches of tire spot checks, only 24 batches, focusing on the outer edge size of the new tire, the height of the tread wear mark, the resistance of the tire without inner tire shedding, the strength performance, the durability performance, the low pressure performance, the high speed performance and other 7 items were tested. It was found that 2 batches were unqualified, and the failure rate was 8.3%, which showed an upward trend compared with last year.
The unqualified products are produced by Shandong Hongsheng Rubber Technology and Shandong Shouguang Framax Tire respectively.
safety belt
Seat belts were spot-checked in 46 batches, 2 batches were unqualified, and the failure rate was 4.3%.
The main reason for the unqualified products is that the product structure design is unreasonable, the quality control of key components is not strict, resulting in the fracture, disintegration and shedding failure of the buckle, and the protection role is not in place in the dynamic test.
Exterior lights
In the random inspection of external lighting and light signal devices of motor vehicles, 4 batches of 56 batches of products were unqualified, and the unqualified rate was 7.1%. The non-conforming items are light distribution performance and photometric performance. Light distribution performance refers to the distribution of light emitted by the lamp in space, and photometric performance refers to the brightness of the light to meet the specified lumen value, which directly affects the safety of driving.
This can't help but remind Mego of Chery's Tiggo 8 in the past few months, the headlights have been complained that the range of the headlights is not enough, the brightness is not enough, and the owner may be able to ask a third party to detect a report if he has the conditions.
Brake fluid
Brake fluid is messy. The municipal supervisor greatly sampled 155 batches of products, and 25 batches were unqualified, and one was suspected of counterfeiting, with a failure rate of 16.1%. Looking at the list, basically can not be searched on the Internet, what British shell petrochemical, obviously touched the porcelain British Shell.
Brake fluid is directly related to brake performance, but also a deadly thing, can not be sloppy. In the unqualified items of random inspection, the unqualified motion viscosity project will increase the viscous resistance in the pipeline, and the brakes will become hard and difficult to step. The failure of the equilibrium reflux boiling point and wet equilibrium reflux boiling point project will cause the brake fluid line to generate steam at the boiling point of the oil temperature, resulting in air resistance and reducing the braking efficiency of the brake oil. Failure to pass the evaporation performance project will cause the brake fluid to boil and bubble easily during emergency braking, which will reduce the braking efficiency or even fail. If the pH is too high or too low, it will cause corrosion of parts in the braking system, resulting in brake system failure.
Engine lubricating oil
The results of the random inspection of engine lubricating oil are good, only 4 batches of 147 batches of products are unqualified, and the unqualified rate is 2.7%. Only one of the gasoline engine lubricants is unqualified, and the brand produced seems to be called Golden Helmet Lubricating Oil.
Gasoline detergent
Gasoline detergent is also what we often call fuel treasure, which has the functions of inhibiting sediment, anti-emulsification, anti-rust and so on. This time, 78 batches were randomly inspected, and the unqualified rate was as high as 56.4%, that is, 44 batches were unqualified, of which 2 batches were suspected of counterfeiting. It seems that the probability of buying fuel treasure to step on the thunder is still quite large.
Moreover, among the production units involved, there are well-known enterprises such as Izumitsu, 3M, Total, and even SAIC Passenger Cars and Changan Ford, which have to be noted. The table is a bit long, the next time you buy fuel treasure, you can refer to it, choose carefully.
Of course, for the utility of fuel treasure, there are different conclusions so far. It is said that fuel treasure is iq tax, and now the quality of gasoline is very reliable, and there is no need to add fuel treasure; if inferior products are used or overused, it will increase carbon deposits and damage the engine. It is said that the existence is reasonable, fuel treasure has been developed for so many years and is still selling, proving that it is effective, not to mention that many OEMs also recommend to shake the fuel treasure in their own cars.
Brother Man feels that well, the fuel treasure of this thing, indeed can not be used without, especially the new car basically does not need to be used, it is not self-defeating. And the old car for several years, carbon deposits and sludge are also very serious, and they are used in vain. So basically those three or five years of cars are used according to the situation.
