[Aika Car Daily Car Original]
With the rise of short video platforms, we can see a lot of car knowledge sharing, these contents have experience, can help the lack of understanding of vehicles and driving groups to make up lessons, the original intention is worth affirming. But in these contents, there is also some crap. For work reasons, I can always brush up on some car knowledge content, some of which really make my scalp tingle, and once thought that big data was despising my business capabilities.
Today we will talk carefully about the dross in these car knowledge, and explain the unreasonable places clearly, one is to avoid the pit, and the other is to be able to explain the reason clearly with the relatives and friends around them, so that more people can avoid the pit.
Coke wash headlights
This "magic trick" is definitely a reserved item in the so-called car knowledge, in fact, I personally think this is relatively good, after all, it will not bring too much loss. It was nothing more than a large bottle of Coke, the hands were slimy, and at most it was quietly ridiculed by others, and it was not a big deal compared with the next few. Of course, the premise is that the headlights do not enter the water.
Generally speaking, the content of this topic will tell you that the car headlights will be yellowed after a long time, and the lighting effect will be affected, and it can be easily solved by wiping it with a barrel cola. Other content authors will use this as a basis to choose to add other recipes, such as beer.
Folk remedies will not talk to you about theory, we can only figure it out for ourselves. Looking at the ingredient list, you will find that the ingredients of cola contain citric acid, and citric acid is also used in detergents. Probably this is the theoretical basis for washing the headlights with Coke.
Next, we will understand the cause of the yellowing of the lampshade, and then prescribe the right medicine. Lampshade panic is a normal natural oxidation phenomenon, which is the characteristic of plastic, although the car lampshade has to add UV coating to prevent oxidation, but the coating will gradually disappear with time, and eventually yellow.
At this point, everyone must understand that even if Coke can wash away the oxide, it cannot play a protective role. At this time, the lampshade needs not only cleaning, but also renovation. There are already related professional projects in the automotive aftermarket service, which not only help polishing, but also re-plating to isolate the oxidation reaction, and the price is not expensive. Before seeing a set of data, it is said that Chinese consumers change cars in an average of three years, and people like me who drag their legs are estimated to be enough to use once, so you really don't need to struggle in this matter.
Sanding shades first requires sandpaper of different specifications
Coke washing headlights is really useless, first of all, he can't cure oxidation and yellowing, and secondly, the stains that can be washed off with Coke can be washed off when you go to the gas station automatic car wash. It seems that the best home for cola is still the stomach.
Toilet cleaners reduce fuel consumption
Compared to Coke wash headlights, the risk factor of this rises sharply. It is difficult for me to link the toilet cleaner with the fuel consumption, is it not possible that there is new energy? Later, when I watched the video, I learned that it was originally a three-way catalyst for cleaning with the toilet spirit...
The image on the left is actually a lambda sensor
With increasingly stringent emission standards, ternary catalysts are already an important part of fuel vehicles, humble but critical, and not cheap.
If you have friends who are engaged in the second-hand car business, you can ask them how much they can sell for three yuan, as far as I know, a few thousand is no problem. The reason is very simple, ternary is just needed through emission regulations, and the manufacturing cost is high, ternary actually refers to three precious metals - rhodium (Rh), platinum (Pt), palladium (Pd).
Schematic diagram of a three-way catalytic converter
Generally speaking, with the use of the car for a long time, the three-way catalytic converter will also occur aging, fouling, performance decline, resulting in vehicle exhaust is not smooth, the most direct impact is that the same power, the old car than its "young" needs the engine to provide higher speed, so the fuel consumption will increase.
So can cleaning a three-way catalyst with a toilet cleaner solve this problem? Not only can it not, but it will also bring side effects. Cleaning the three-way catalytic converter requires a special cleaner, an important criterion for the special cleaner is that it cannot be corrosive, and the composition of the toilet cleaning spirit contains acidic substances, how to dilute is a technical problem. In addition, once there is a problem with the self-cleaning, you can only pay for it yourself.
In general, the problem of the three-way catalyst must first determine whether it is a hard injury at the physical level or needs to be cleaned. If it is a hard injury, it is recommended to replace it directly, if it can be cleaned, find a professional and regular store. Here is an aside, if there is a dealer who recommends cleaning when you first guarantee, then please resolutely refuse, it is completely unnecessary. My friend's friend had a similar experience, which was a lesson for money.
One-click boot is actually three-button boot
"The whole network has the attention of the car, a key to start the function and a foot brake directly ignited, I told you that it was wrong ..."
According to this brother, the vehicle factory set two "start gears", each has its own uses, the correct approach is to first press the start button, let the vehicle self-test, and then step on the brakes and press the start button to ignite.
There is also a saying that pays more attention to the "sense of ceremony" than this, the first step is to press the start button to let the vehicle self-test, the second step is to press the start button again to make the vehicle weak, so that the oil pump is in a working state, and the third step is to press the start button while pressing the brake to complete the ignition.
Good guys, if that's the case, then everyone can apply for a refund of one and lose three.
Instructions for ignition in the product manual of a certain model
One-click start as the name suggests, press it, we will find that when the vehicle starts, the lights on the dashboard will light up a lot, including but not limited to engine fault lights, airbag fault lights, in fact, this is the vehicle has begun to self-test. Moreover, the self-test process is carried out all the time.
There are also two "start blocks" this statement is also quite funny, two blocks this statement is correct, but these understanding buddies obviously misunderstood the use. The vehicle is not powered on to complete the self-test, but simply to energize, for example, we are waiting for people, you can only power on without starting the engine, both listen to music to charge the mobile phone, but also to avoid the vehicle idle for a long time waste of energy.
Speaking of oil pumps, the oil pump can retain a certain pressure value after the flameout to ensure the use of the next ignition, so there is no need to understand the "warm-up" said by the brother.
To sum up, one-click start is literal, just press once. If you really believe the above nonsense, it is like torturing yourself.
Write at the end
According to my observation, this kind of car knowledge firmly grasps a pain point of car owners - afraid of loss, afraid of spending more money unjustly, afraid of bearing economic losses that should not be there. Useful car knowledge can indeed avoid pitfalls, but these dross can only trap themselves in pits that could have been circumvented. In the final analysis, the threshold for content production is low, and information is flooded. At this time, we should think more carefully about whether this so-called knowledge is reliable, but this also deviates from the original intention of obtaining useful information at low cost, which is quite magical. The author of the two-button start in the video said, "It's not easy to say that the car is not easy", it is really not easy, I suggest you don't say it.
