Some netizens teased, "I have a car, but I can't drive it. Hey, it's just for fun." Old Tie, you have been "playing" like this for a long time, not only hurting your car, but also being sad! As the saying goes, "running water does not rot, a family does not bite", which also applies to cars. Some car owners don't use the car often for various reasons after buying a car (normal car frequency: ≥ twice a week, driving ≥ 100KM per week), but if your car is stopped for a long time and you don't pay attention to maintenance, it is easy to have problems, such as tire aging, battery power loss, gasoline deterioration, oil oxidation and so on. Today, I will teach you some maintenance tips when your car is idle for a long time.
First, the tire pressure should be sufficient and the parking space should be "cool"
Tick-tock, tick-tock, with the passage of time, the air in the tire will gradually disappear, so the tire pressure will drop. Temperature changes will also affect the air pressure in the tire. Insufficient tire pressure makes the tire bottom easily deformed. At the same time, if the parking time is too long, with the aging of rubber, the tire may be difficult to recover, so the tire can only be replaced. It is suggested that you increase the tire pressure appropriately, effectively reduce the tire deformation and slow down the damage to the tire caused by long-term parking. The recommended tire pressure parameters can generally be seen on the B-pillar of the main driver. If you don't want to use the tire pressure recommended by the automobile manufacturer, the tire pressure can generally reach 2.4bar, which can be used all year round. In addition, park your car in a place where there is no sun exposure to prevent the tires from cracking.
Second, the battery should be kept fully charged.
The battery on the car is most likely to be "injured" when the car is not driven for a long time. Lead-acid batteries in automobiles will self-discharge even if they are not used. Generally, self-discharge every day and night will reduce the capacitance by more than 1%. If there are still electrical appliances in the car or the technical condition of the battery is not good, the self-discharge rate will also increase greatly. When the battery capacity is less than 70% of the standard capacity, sulfide will be produced on the surface of the electrode plate inside the battery, causing irreversible damage, and the service life of the battery will be greatly shortened, or even scrapped in advance.
Therefore, before the car stops, it is necessary to keep the battery fully charged, turn off all electrical appliances and remove the negative connection of the battery, which can reduce the discharge rate of the battery and prolong its service life. If you don't want to unplug the negative electrode, it's best to check the battery once every two weeks, such as whether the electrolyte height is higher than the electrode plate 10 to 15mm, and if it is insufficient, add distilled water.
Third, the airtight fuel tank can not be ignored.
When it comes to ensuring that the fuel tank is sealed when the vehicle is parked, you may think that this is done to avoid gasoline volatilization, but the most important significance of this is to prevent gasoline from deteriorating. Because storing gasoline for too long will make some substances lose, and the antiknock performance of gasoline will be reduced. That is to say, if 95% gasoline is added, it may become 92% after a period of time. If it explodes while using the car, it will damage the engine. So when we plan to stop using cars for a long time, try not to store too much oil in the fuel tank. If it is found that the air tightness is poor, you can block the oil filler with plastic film and tighten the sealing cover.
Fourth, drain the oil before stopping for a long time.
"Engine oil, gearbox oil, brake oil, oil filter, fuel filter and air filter" all have a service life. When the car is parked for a long time, the phenomenon of oil oxidation will be very serious. After the oil is oxidized, on the one hand, the lubrication effect will become worse, on the other hand, some acidic substances will also cause corrosion to parts. When the engine starts again, dry friction or semi-dry friction will be formed between the cylinder and the piston, which will accelerate the wear of parts and make it difficult to start. Therefore, be sure to drain the engine oil and the antifreeze in the cooling system.
If you don't use it for a long time and don't pay attention to maintenance, it is a kind of harm to the car, so if you don't drive often, you should pay attention to the above maintenance tips. If possible, start the car once a month, let your car walk and ensure the "health" of the car. Or you can entrust others to drive for a period of time every month, which can keep the car in good condition.
