Simple knowledge of automobile sun protection and maintenance

As summer approaches, simple knowledge of car sun protection and maintenance can be seen at a glance.

Summer is approaching step by step, and every season, car owners will be more agitated, because the weather is getting hotter and hotter, which will lead to a significant increase in car failures. If you don't take good care of it, such as "the water tank boils", "the engine sticks to the cylinder, spontaneous combustion, flat tire, paint drying, ... and so on. So how can we do a good job of protection or solve the problems caused by summer heat?

Sunscreen mode

1. Stick explosion-proof membrane. Cars are often exposed to the hot sun for a day. Long-term exposure is bound to accelerate the aging of the paint surface and dashboard, and even have the danger of spontaneous combustion. Sticking explosion-proof film to the car can effectively insulate the heat. Although waxing also has some effects, any car wax contains silicon. Exposure to ultraviolet rays for a long time will corrode the car paint, leaving black spots, and will not enhance the hardness and resist ultraviolet rays.

2. Car clothes Car clothes can not only prevent cars from freezing in cold weather, but also prevent cars from being damaged by accidental factors such as falling objects, fireworks and firecrackers. In summer, it can also play the role of sun protection, effectively preventing vehicles from being directly irradiated by ultraviolet rays.

3. Sun visor, the sun visor should choose the front windshield sun visor with silver reflective heat insulation layer, which can not only be moisture-proof and waterproof, but also effectively reflect ultraviolet rays and reduce the heat in the car.

4. Wet towel, which is a more economical and practical method. Putting a wet towel on the dashboard (not too wet) can effectively reduce the temperature near the dashboard under direct sunlight, so that the temperature in the car will not be too high when driving, and it will be more comfortable in the car.

Try to find a cool place to park, such as private garage, underground parking lot, parking lot with carport, etc. In order to prevent the car from being irradiated for a long time. If not, you can put the car in the shade of the building. But pay attention to the time and the angle of the sun, it is not easy to put it for too long; For example, you can park on the west side of the building in the morning and try to park on the east side of the building in the afternoon. If you want to park all day, try to find the best location with buildings on both sides. If not, choose to park on the east side of the building. This can avoid the afternoon with the strongest sunshine and the longest time, and reduce the impact on the car.

6. Under the big tree, if there is no place, it is also good to choose to park under the big tree, but pay attention to (1) bird droppings and gum (2) Thunderstorms and windy weather may cause trees to fall down. But before parking, it is best to observe whether there is a lot of bird droppings or chewing gum under the tree. If there are many, don't stop. Not only will it be difficult to clean, but it will also corrode the car paint.

7. If there is really no place to park in the sun, then choose to point the rear of the car at the sun to reduce the area directly exposed to the sun and make the temperature inside the car less high.

8. Leave a small gap in the window, which will help air convection inside and outside the car and eliminate heat and harmful gases inside the car, but it must be safe.

Prevention law

1. Do a good job in car maintenance and check the air conditioning system of the car. Car air conditioners are used most in summer and need maintenance most. When put on hold in winter and spring, a lot of dust and bacteria will accumulate in the air conditioner. At this time, it is necessary to replace the filter element of the air conditioner and clean the air duct of the air conditioner. The first is to clean the dust and bacteria on the wall of the ventilation pipe, which is the only way for the air outlet of the air conditioner; Then test the pressure system and check whether the refrigerant is sufficient; Secondly, check whether there is any leakage in the flow of bubbles through the glass observation hole on the drying tank; Finally, clean the dust in the evaporation box.

2. Due to the high temperature in summer, when the vehicle is driving, the engine is easy to overheat and the water tank "boils"; Therefore, the engine cooling system of the vehicle should be inspected and maintained frequently, including water tank, thermostat, water pump and fan. Moreover, pay more attention to the temperature of the water thermometer during driving. When the water temperature exceeds 100℃, stop the engine in time, but don't shut down the engine immediately. You should let the engine run at idle speed and gradually cool down, and at the same time open the engine compartment cover to facilitate heat dissipation. If possible, the cooling water can be gradually filled in several times.

In addition, there are three taboos when the water tank is boiled: one taboo is to turn off the fire immediately; Second, avoid opening the lid and add cold water immediately; Don't throw cold water on the engine. Because these three methods will cause cylinder sticking, hot water spraying, cylinder quenching and cylinder explosion, and the consequences are unimaginable.

3. How to prevent tire puncture? Due to the high temperature in summer, the road surface temperature is often above 70℃, and if the automobile tire is driven for a long time, the air pressure in the tire will increase, which is easy to cause a puncture. Most puncture cases are often caused by high tire pressure. However, there is a misunderstanding here. In fact, too low tire pressure may also lead to the danger of puncture. Because when the tire pressure is too low, both sides of the tire will contact the ground in a large area, resulting in "tire rubbing", and the tire will contact the high-temperature road surface more, which will lead to gas expansion in the tire and easily lead to tire puncture.

4. Prevent high-temperature spontaneous combustion. Cars driving in the hot sun for a long time can easily lead to high-temperature spontaneous combustion. There are many reasons for automobile spontaneous combustion, such as automobile oil leakage and wire aging, which account for the vast majority of automobile spontaneous combustion accidents. Generally speaking, there are several reasons that will greatly increase the probability of spontaneous combustion: the gas pipe leaks and the wires are aging; Oil and gearbox leaks; Electrical appliance modification; Improper maintenance causes the engine to be too dirty; Human factors such as smoking and storing lighters. Any of the above factors may lead to spontaneous combustion accidents, so it is recommended that car owners do not ignore any details.

5. Beware of engine cylinder explosion, summer rainfall increases, and heavy rain hits the city from time to time. At this time, car owners who drive in rainy days should pay attention to it, and it is inevitable for cars to wade on low-lying roads that are easy to accumulate water; What should I do if there is water inflow and flameout? At this time, turn off the ignition switch immediately, and don't try to start the engine again to prevent the cylinder from bursting after the engine is forcibly started.

The vehicle should be moved to a safe place, as high as possible before it is low, so that the water entering the exhaust pipe can flow out to avoid damaging the three-way catalyst and muffler. If water enters the engine, remove the spark plug, manually cut off the oil supply system and the ignition system, and then run the engine with the motor, so that the water entering the engine can be discharged smoothly.
