Let's be honest. I'm from Hubei. At the end of 2020, the new coronavirus outbreak came. The day after wuhan closed the castle, the city where I lived also closed the castle. All districts were also closed. No one can get out of the car. All the cars in the neighborhood are parked there. It took more than two months. My car couldn't drive for two months. I was always worried that the battery would run out of battery, but after that, I opened the envelope and tried it, and it was ok. It can also ignite. The tire pressure is a bit low, nothing wrong with that except for being below 2.0 bar. My car is a domestic brand and has been driving for 7 years. I asked if it would affect a car parking for a month? The car stopped motionless, and the answer is that usually there is no big problem, but it does have some impact. While cars don't break, the legend of fragility is true, but occasionally shelving for a month isn't enough to damage a car. If you leave it for more than a month, it is easy to have problems. So, how long is the car placed prone to problems, and what kind of impact will it have?
In general, cars are placed continuously for more than 75 days, or one-third of the time of the year. That is to say, if it is placed for 4 months within 12 months, it is prone to problems. The main problems are as follows. 1, car battery, car battery is the most fragile parts. The general car battery is a lead-acid battery, which uses chemical reactions to convert chemical energy into electrical energy and provide it to the car for use. The electrical energy stored in the battery is not fixed, but often changes. If the car does not move, the battery will attenuate. If it is running every day, the generator will automatically charge the battery every time it is running until it is full. Car battery discharge, the battery is how to maintain the best working condition for a long time in the charge and discharge. If your car is always moving, the battery will become discharged. Studies have shown that the battery discharges about 1% of the full charge of the battery every day, and 100 days is equivalent to 100%. In fact, if the battery charge is less than 25% of the total charge, the car will not start.
That is to say, when the battery is fully charged, as long as it is placed for more than 75 days, the battery cannot start the vehicle. At this time, in order not to catch fire in the car, it is necessary to ask for help from the outside to charge the batteries of other cars. It doesn't matter if it happens once in a while, otherwise the battery will be scrapped as soon as possible. Of course, the discharge of different car batteries may be somewhat different. That's the average, and that's what most cars do. At the same time, this is also related to the age of your car. The battery itself has a lifespan, usually 3 to 8 years, and if you put a car that cannot be driven often, the life expectancy will be shortened by at least 20 to 30%. The car is not equipped with a battery for three months is not enough electricity, can not start the vehicle 2, tires, a car that has not been placed for a long time, the impact on the tires is very large, please take a closer look. Generally speaking, for a car that is placed in one place for a long time, the tires usually leak air. This is because the car was not shelved. Tires in a certain position are subject to the weight of the car. A vehicle weighing at least one ton can withstand four tire-fixed positions. Over time, the tire will deform. This is a physical injury to the tire, generally no more than 3 months after driving, the tire will begin to be affected. The specific situation is related to the life of the tire, the use time, the quality, and the model.
Secondly, if you don't drive for a long time, the tire pressure in the tire will be lower and lower. Tires move in circles while driving, and all aspects of the tire are evenly stressed. Trolley tires do not have inner tubes. The tires are embedded directly into the hub, and when inflated, the tires and hubs are firmly pressed against the air pressure. When driving, the tire is stressed, and on the other hand, the tire pressure will temporarily rise after being heated. If the car does not move for a long time, the tire will burst, and when it is not driving, if the tire is partially forced, the gas will slowly leak and the tire pressure will become lower and lower. Generally, a tire pressure of 0.01 to 0.02par is released every day. If you don't drive for a month, the tire pressure of 0.3 to 0.6par will drop. For example, if your initial fetal pressure is 2.5par, it will become 1.9 to 2.2par after a month. At this time, it is finally possible to drive, if it is placed for more than 3 months, the tire will not work, and it will not be able to drive normally if it is not inflated. That's the impact. Also, because the car can't be let go, the dog is prone to peeing in the tires. Dogs' urine has a corrosive effect and will shorten the life of the tire.
The car will reduce the tire pressure for a long time, and the material of the tire is rubber. Rubber has a lifespan. There is no life expectancy without. Generally 5 to 8 years or 5 to 100,000 kilometers. It depends on your personal circumstances, but even if you don't drive for five years, you have to change your tires. Because life expectancy has come, the car is afraid of being shelved, afraid of driving, and cannot drive. 3, the surface of the paint, if placed for a long time, the third impact on the car is the surface of the paint. If the car can't be driven, naturally it can't be washed. The surface of the car will accumulate a variety of dust, impurities, leaves, bird droppings, bird droppings, plant fruits and so on. In addition, exposure to the sun and rain will cause great damage to the surface paint. Bird droppings and plant berries have a corrosive effect, and if they are not cleaned for a long time, they will merge with the paint on the surface of the car and become unclean. If it is hard, the paint on the surface will fall together, causing the surface of the car to rust, which seriously affects the paint quality of the car surface. Once rusted, it is difficult to dispose of, so the treatment must start with the paint of the lowest layer. Not driving for a long time will affect the paint of the surface, so when parking, it is best to park in the underground garage. If you have to stop outside, don't stop under a tree, it's best to stop in an empty place. Even when exposed to sun and rain, it is easier to clean up than rotten food.
4, the engine room, if you do not drive for a long time, small things will enter the engine room for heating, or worry that the mouse will bite off the battery of the engine room. It's a big project. Sometimes the car is parked under a tree, and there are fallen leaves that enter the engine compartment along the gap between the windshield and the engine compartment. To drive, these fallen leaves must be removed. Otherwise there will be an impact. 5, the influence of various oils, lubricating oil, the car interior has many like engine oil need oil and lubricating oil precision parts. When the car is working, the oil enters the engine from the oil pan and lubricates the components. As soon as the car does not move, the oil returns to the oil pan. If it is not operated for a long time, the important parts inside the car will not be protected by oil, and the longer the time, the drier the parts will be. If the car does not move for a long time, garbage may enter the engine compartment
The oil has a shelf life. If the oil pan settles for a long time, the shelf life will also pass. The next time it needs to run, suck the oil into the engine again, but it will take time. If the oil does not fully penetrate during cold start, the engine will wear out for a short time. This can damage the engine. The more cold starts there are, the greater the wear and tear of the engine and the shorter the lifespan is often shorter than before. Therefore, even if it is not running, please change the oil according to the usual maintenance time. Don't think you can refuel less without driving. Please replace it normally as well.
In summary, it does not matter if the car is temporarily put on hold for a month. Occasionally put once a month, the impact is not obvious. However, if the placement time becomes longer at a time, or if you always drive for a month or two days for a month, the impact on the car will become greater, so try not to place the car. Only a broken car will put a broken car on hold.
