I believe everyone has heard of such a sentence: the car is not damaged, it is damaged and repaired. This situation is not uncommon in recent years, especially in the beginning of 2020, because of the epidemic, many friends can not go out, quarantine at home, even in 2022 the epidemic is repeated, the car will inevitably encounter a long period of parking.
There will also be other situations that lead to long-term parking of the car, such as the owner of the car back to his hometown, etc., so many people will think of every two or three days to put the car on fire, let it idle for two or three minutes, the car moves anyway, the battery will not lose much electricity, so that it can effectively avoid the harm caused by the long stop of the car? This is not true.
First, what harm will the car bring when parked for a long time
The first thing that will affect is the tire of the car, the car parks the tire for a long time and does not move, then it will have a long time of force in some place, and the force area is relatively small, which will lead to the possibility of deformation of the part, which will have an impact on the life of the tire, and other iron components such as brake discs are also easy to rust.
Secondly, various parts of the car that need to be lubricated, such as the engine, gearbox, including air conditioning and other components, cannot be lubricated, which will inevitably make some places that need to be connected inadequately lubricated, and even oil leakage and other phenomena. So can setting the car on fire every two or three days and idling for a few minutes solve these problems?
The answer is no, because the tires of the car are still immobile when idling in situ, and many cars now use lead-acid batteries, and lead-acid batteries will self-discharge even if they are not used.
Some friends said that the car does not need to be fired often, only need to remove the negative electrode of the battery, in this case can indeed reduce the loss of battery power, but the lead-acid battery itself will self-discharge, even if the positive and negative poles are removed, the battery is removed and placed still, it will also slowly discharge, and the speed of discharge will be determined according to the service life of the battery, the fastest time can be put off 20% of the electricity every day, it is possible to put on a week the battery will be out of power.
How does the battery charge? Generally charged through the generator, so the engine can achieve the effect of charging when running, idling is the same principle, but many car owners have ignored a point, that is, the speed of battery charging is very slow, it is possible to start the car every time it is fired, the new battery consumes about 3% of the electricity, and for the older battery, it may consume 20% or even more of the electricity.
Second, the solution
In summary, just rely on idle speed to ignite these few minutes, through the engine to drive the generator operation, is far from charging enough, often do this may hurt the car, because the car for a long time idle if not open, the cold car start a moment will make the engine produce too much carbon deposition, wear is also more serious.
The safest thing to do is to drive out for a spin every two weeks, at least 20 minutes or more, to be able to charge the battery more and lubricate the engine, transmission and other systems.
Therefore, the car needs to be parked for a long time, and it does not need to be idle once in two or three days, nor does it need to remove the battery, if the car is an old model, after the car is lit up every other week, the in-situ heat car is heated for a few minutes, and then the car is driven out, driving normally for half an hour, so that it can play a normal maintenance role for the battery, tires, and engines.
