In the blink of an eye, the hot and hot summer is getting closer and closer. Many car lovers equip their cars with a lot of automotive accessories in order to make their travels more comfortable. In addition to these external supplements, the internal maintenance of the car and daily driving habits are also very important. Let’s share some tips for dealing with high-temperature travel.
[Cooling car supplies]
1. Car refrigerator. Car refrigerators are most popular among young car owners. It can hold mineral water, cola and other drinks and fruits. Just plug the power plug of the refrigerator into the car's cigarette lighter and it will work normally. Some simple refrigerators do not require a power supply and can just use ice cubes. Car refrigerators using semiconductor principles are basically both hot and cold. It is used for cooling in the summer and can also be used to warm drinks in the winter.
2. Move the ice pack. Put the ice pack in the refrigerator for 10 hours, then put the drink in, and the temperature will drop to low temperature in a short time. The ice pack can self-preserve for several hours.
3. Cooling pad. Replacing your car chairs with cool cushions in summer is also a good way to lower the temperature. Currently, there are many types of cooling pads on the market. In terms of materials, there are many types such as linen, ice silk, bamboo grass, etc. In addition, manufacturers launch some new products every year, so the product types in the cooling pad market are dazzling.
4. Heat insulation film. In the hot summer, car owners should consider affixing a layer of film on the car windows exposed to the scorching sun that can effectively block ultraviolet rays and heat. Car insulation films are divided into front, rear and side windshield films. Among them, the front windshield has the highest requirements for thermal insulation film. In addition, the higher the UV resistance index of the thermal insulation film, the better. The optional heat insulation film for the side windshield is more flexible and the colors are more changeable. In addition, the thermal insulation effect of the thermal insulation film is not directly related to the color depth. The coating process in the thermal insulation film is the key factor that determines the thermal insulation effect.
[Issues you should pay attention to in hot weather]
1. The engine water temperature is too high and antifreeze needs to be added. High engine water temperature is mostly caused by lack of antifreeze. Park the vehicle in a cool place to cool down. Do not turn off the engine. Let the engine continue to idle. Open the machine cover to dissipate heat. When the temperature drops, add antifreeze to the water tank. Avoid adding antifreeze to the water tank. Pouring cold water on the engine may cause the engine block to explode beyond repair. Some car owners simply use tap water instead of antifreeze. This is a wrong approach because there are many impurities in the water that tend to leave sediment in the engine, water tank, etc., so antifreeze cannot be replaced with water.
2. Check the cooling system and clean the radiator in time. You should also check whether the "thermostat" is working properly, and never remove the "thermostat". Because the "thermostat" is a switch that controls the circulation of coolant, it can keep the engine operating temperature within an optimal range. In this way, the engine will have the strongest power, the least wear and the lowest fuel consumption. If it is removed, it will cause Wear of parts and low water temperature will lead to a decrease in power and an increase in fuel consumption.
3. Clean the water tank and condenser. The water tank and condenser are important components of the vehicle cooling system and air conditioner. As the vehicle is used for a long time, dust, sediment, catkins, etc. will be mixed in the gaps between the two, which will affect the water temperature and air conditioning refrigeration performance. performance.
4. Adjust tire pressure in time. The high road temperature in summer reduces the heat dissipation of tires, which can easily lead to tire blowout accidents. Therefore, the tire pressure should be lowered. After driving a long distance for a period of time, park the vehicle in a cool place to cool the tires naturally. Do not pour cold water on the tires to avoid tire deformation.
5. Avoid spontaneous combustion of vehicles under high temperatures. Vehicle spontaneous combustion is mainly caused by vehicle leakage or oil leakage. If the car is not properly maintained, the parts are aging and the wiring is damaged, it is easy to leak electricity. The fuel tank is prone to oil leakage if it is corroded for a long time. Therefore, to avoid spontaneous combustion under high temperatures, we must start with car maintenance.
6. If the air conditioner is used frequently, the air duct and filter element should be cleaned in time. Furthermore, pay attention to refrigerant leakage and poor refrigeration. This is usually caused by the aging of the sealing rubber ring in the pipeline, abnormal refrigerant pressure, or damage to system components. Also pay attention to the working condition of the cooling fan.
[Develop good driving habits]
1. Do not use the internal circulation of the air conditioner for a long time. The principle of internal circulation is that air circulates in a closed space in the car, which causes the oxygen content in the car to continue to decrease. Moreover, if the gasoline in the cylinder is not completely burned, the unburned carbon monoxide in the engine may also leak into the car. , so the air quality in the car will get worse and worse, and even cause harm to the human body, so the internal circulation cannot be turned on for a long time. This is why you cannot sleep in a car with the internal circulation on.
2. Avoid starting the car under the scorching sun and turning on the air conditioner immediately. In the summer, many cars have the experience of being exposed to the scorching sun. Even if they are sometimes parked in a cool place, it is difficult to escape the sweltering air. If you open the door and get into the car, it will definitely be hotter inside than outside. Many people will start their car immediately, turn on the air conditioner, and increase the wind speed to achieve the fastest cooling effect. In fact, this is not reasonable. The correct way to dissipate heat is to lower the glass on both sides after starting the car to allow air convection outside the car. This can not only quickly reduce the temperature inside the car, but also effectively reduce the load of the air conditioner during subsequent cooling. After three minutes, the engine speed is stable, then retract the windows and turn on the air conditioner, so as not to cause damage to the engine.
3. Avoid turning on the air conditioner idling for a long time. Using the car's air conditioner when parked and idling for a long time will have a negative impact on the engine's cooling system, battery system and the entire air conditioning system. At this time, if it is determined that the waiting time for parking is long, it is best to turn off the air conditioner, lower the windows or turn off the engine and leave the car. This will not only save fuel consumption, but also extend the service life of the car air conditioner.
