This year's Spring Festival homecoming is still not peaceful, sent away the Delta variant, and came another Omicron. So the problem is, if this year is still the new year in place, many vehicles are facing a small half a month of sealing.
In this short period of one month, what is the harm to the car when the vehicle is parked?
What kind of preparations do the masters have to do before parking and sealing and before they are activated?
Today, Tiger came to talk to the masters about the injury and preventive countermeasures for parking the car for a long time.
After the power out, the whole car did not lose power
Even the best battery can lie down within 45 days
In the cognition of many masters, after the car is turned off, it is like pulling the brake
In fact, in the state of vehicle shutdown, the dashboard clock, engine anti-theft, and the system in the car are all consuming power.
Take the ordinary family car battery with 60Ah as an example:
The sum of the dark current of the silent electronic system of the whole vehicle is about 20mA, and the normal power consumption can meet about 120 days, and the full calculation is almost four months. However, the theory is far from keeping up with the actual situation, and the vehicle battery voltage is not constant. As the battery naturally discharges, the battery voltage will continue to decrease.
When the power is less than one-third, that is, after 80 days of standing, the car engine is very difficult to start.
And now the more popular modified electric tailgate, keyless entry, positioning equipment, etc. will significantly increase the vehicle static dark current.
Therefore, if the vehicle is stored for more than 1 month, it is recommended to cut off the negative electrode of the battery to prevent power loss.
So how often is it charged, how long is it rushed? How much does it cost?
Earlier Tiger said that the vehicle safety storage cycle is 30-45 days.
At this time, the battery loss is 15Ah, calculated by the idle charge current 30A, according to the 1L/h fuel consumption, the oil price is 8 yuan, and the idle speed is 30 minutes.
Some cars equipped with standby function activate functions similar to the new car transport mode, which can extend the storage period to 7 months without losing power.
Repaired tires are more likely to have dark leakage deformation
During the long-term parking process, the weight of the entire car is concentrated in the small part where the tire and the ground contact.
Seemingly not tight, the actual tire force is uneven, the surface will be irreversible deformation.
Now the tires of the car are all based on the air pressure hoop on the steel rim, and there will be natural air leakage.
Generally, the normal loss is about 0.07 bar / month, when the natural air leakage to less than 2.0 bar, the adhesion will be significantly reduced under the long-term deformation of the cord layer inside the tire.
After 32 hours of parking, the adhesion between the tire cord and the rubber will begin to decrease.
After more than 43 days of parking, the adhesion of tire rubber to the cord layer dropped from 1100N to 1000N (10% reduction in strength).
For a long time parking, it is recommended to adjust the tire pressure to 3.0, mainly to prevent the long inventory time and cause the tire to lose gas.
The national standard also stipulates that the maximum tire pressure of the tire should not be greater than 3.5 bar in the gbT2978-2008 year.
The paint is mottled like "zombies" are all gum and bird droppings
Long-term parking, the impact of wind and sun on the paint surface is on the one hand, if the gum, bird droppings fall. Will have a certain degree of corrosiveness to the paint resin material, do not underestimate such a small piece, long-term do not clean the corrosiveness is still very strong.
No car wash in 2 weeks, bird droppings on trunk lids were not cleaned. Although it was only the size of a thumb nail, when it was cleaned up, the paint was no longer shiny. Many people do not believe that bird droppings can be like this, but many cases prove that bird droppings are more harmful than shellac rust.
It is recommended that the grandfathers have the condition to park the underground garage as much as possible. If there are no outdoor parking conditions, you can choose to cover it with car clothes. Even if you don't have a car coat, find a plastic sheet, waste curtain cloth or something, you can also respond to the emergency.
Is there a better way? Of course, the crystal-plated and invisible car clothes can form a strong protective layer on the paint surface of the vehicle. Not only are water droplets easily slipped on the plating layer, but also common paint damage such as sun, bird droppings, and gum cannot directly damage the paint surface.
Finally: there is a saying that the car is broken, not broken, so long-term parking is not used, on the one hand, it is a waste of the car, on the other hand, there is damage to the car.
