The hot summer has arrived. For convenience, many people choose to travel by car. After all, it will be cooler and more convenient to drive by yourself. But there will be some trouble in using the car in summer. For example, after a day of sun exposure, the temperature inside the car is very high. At this time, there is always a feeling of heatstroke when entering the car, which makes people very unhappy. So what problems should you pay attention to when using a car in summer?
The most important problem to pay attention to when using a car in summer is the air inside the car. In summer, the weather is hot and the sun is exposed. Many cars parked in open-air parking spaces are exposed to direct sunlight, and the inside of the car is a relatively closed space. At high temperature, many parts or car supplies placed by the owner may emit some harmful gases, which is very harmful to human body.
After getting on the bus, many people will choose to turn on the air conditioner immediately. In order to make the temperature meet their requirements faster, they don't even open the window. This operation will prevent harmful gases from escaping from the car and cause greater harm to people. This is simply a veritable "suffocation surgery." The correct way is to ventilate the exposed vehicles before use.
When using the car in summer, try not to put some volatile items such as alcohol in the car. Everyone is a car from the heart and often puts some decorations. Among them, car perfume is more common, and perfume generally contains some volatile substances, which are easy to expand and explode when exposed to high temperature. Some men who smoke often keep lighters in their cars for emergencies. Lighters are dangerous at high temperatures, so it is best not to put them in the car.
Summer is the season with frequent traffic accidents, and it is also the most challenging season for safe driving in a year. In order to ensure the safety of driving in summer, drivers and friends are reminded that in addition to strictly observing traffic laws and regulations, they should also pay attention to the "seven precautions" for safe driving in summer.
When you feel tired, yawning, and weak hands and feet during driving, you should immediately stop and rest, or wash your face with cold water to move your limbs, and then drive after your energy is restored and your mind is clear.
First, prevent accidents caused by fatigue driving.
As we all know, driving is a kind of labor that requires a lot of physical and mental energy. Due to the high temperature in summer, coupled with long days and short nights, poor or insufficient sleep, it is easier to get tired and cause vehicle accidents. Therefore, drivers must pay attention to the combination of work and rest and keep enough sleep time. At the same time, they must realize that fatigue can't be resisted or persisted, and only adequate sleep is the only effective way to prevent driving fatigue.
Second, prevent high fever and heatstroke.
In summer, the sun is strong, the temperature is high, the driver sweats a lot, the energy consumption is large, and it is easy to get heatstroke. In order to prevent heatstroke, drivers should avoid eating spicy and greasy food, eat more fresh vegetables, drink more cold drinks, and pay attention to supplementing salt before and during driving. Carry a kettle and towel with you, and prepare heatstroke prevention drugs such as Ren Dan and Shidishui. Keep the cab well ventilated and rest on the way.
Third, prevent brake failure.
For vehicles with hydraulic braking, attention should be paid to checking the quality and quantity of brake fluid to prevent its boiling point from decreasing and forming air resistance, thus affecting the braking effect. Therefore, if necessary, replace the brake fluid (once every two years as required), check the working conditions of the master brake cylinder and the slave brake cylinder, and completely eliminate the air in the brake pipeline. For vehicles with pneumatic braking, the maximum braking working pressure should be checked frequently, and the brake cups and hoses should be checked for aging.
Fourth, prevent tire explosion.
In midsummer, accidents caused by car puncture often occur. Due to the asphalt cement pavement under the scorching sun, the heat wave attacks people, which leads to the increase of temperature and air pressure of high-speed rotating automobile tires, which is easy to cause tire puncture. Always pay attention to the tire pressure in summer, especially before driving on the highway, and check it carefully. Generally speaking, the tire pressure in summer is about 10% lower than that in normal tires. Accurate tire pressure can be measured with a tire pressure gauge, and it is best to go to the maintenance station for measurement. The easiest way to check the tire pressure is to learn to visually inspect the tire, and judge whether the tire pressure is normal by observing the deformation degree of the tire touching the ground. Generally speaking, the normal service life of tires is 3 years or 80000KM. At this time, it is necessary to consider replacing it in time to prevent accidents caused by flat tires.
Five, to prevent wading and ignition after flameout.
Don't blindly force your way through the stagnant water. You should get off and observe the water depth. If the water depth exceeds half the height of a wheel, it is forbidden to wade through it. If the water depth is less than half the height of a wheel, you can wade through it. However, when the vehicle wades, it should adopt a low-speed (low-grade) throttle to keep the speed, and try to pass through shallow roads. At the same time, it is forbidden to pass in parallel when wading, let alone follow or accompany the car.
It is suggested that if the car feels that the power is insufficient in the process of wading, it must quickly step on the clutch and slam on the accelerator several times to increase the engine speed, so as to keep the pressure gas in the exhaust pipe all the time to prevent stagnant water from entering the exhaust pipe and causing flameout. Once the vehicle is found to be turned off by water, it must not be started again, and it should be pushed to a safe place as soon as possible. At the same time, it is necessary to remove the negative electrode of the battery as soon as possible to avoid short circuit of various electrical appliances in the car due to water ingress, and immediately seek the help of garage professionals. Special reminder: The most taboo of wading is that the vehicle is forced to ignite after flameout, which may easily cause the engine to "explode" and cause man-made mechanical accidents.
Sixth, prevent vehicles from catching fire.
The heat wave is rolling in summer, so be careful not to fill it too full. There is a vent hole in the fuel tank cover of the car. If the gasoline is over-filled, the bumps in the driving process will make the gasoline overflow, and the static electricity will cause a fire. Especially remind comrades who smoke not to put flammable items such as lighters in the car. After the car is exposed to strong sunlight, the temperature inside the car is enough to make the lighter explode or spontaneously ignite and cause a fire.
Special reminder for driving in summer
Don't wear slippers and drive too fast.
In summer, asphalt pavement is easy to soften, which reduces the friction coefficient between wheels and pavement and reduces braking performance. Pay attention to control the speed when driving and take measures to prevent accidents.
It is not advisable to turn on the air conditioner for a long time.
Generally, air-conditioned vehicles have better sealing performance. Most people will feel dizzy and tired after staying in this environment for a few hours, and their memory will also decline. At the same time, the people in the car exhaled a lot of carbon dioxide, and the oxygen in the car decreased sharply. Drivers are advised to adjust the working state of the air conditioner properly, or open the window for air every once in a while.
