What are the precautions for driving in hot weather?

First, prevent the engine from overheating: when the ambient temperature is high in summer, the engine is prone to overheating. Therefore, the inspection and maintenance of the engine cooling system should be strengthened in summer, and the scale in the water tank and water jacket and the sundries embedded between radiator fins should be removed in time. Second, prevent the battery from losing water: the high temperature in summer makes the water in the battery electrolyte evaporate quickly, the liquid level drops rapidly, and even the polar plate is exposed under the liquid level, which leads to the early water loss damage of the battery. Therefore, the liquid level in the battery should be checked frequently in summer, and distilled water should be replenished in time.

Third, the puncture tire: In summer, the air pressure in the locomotive tire will increase with the increase of temperature, which is easy to cause a puncture accident. Therefore, it is necessary to appropriately reduce the tire pressure before driving. If the tire temperature is too high while driving, stop the car in the shade to cool down, and don't use cold water to cool down.

Fourth, prevent high fever and heatstroke: in summer, the sun is strong, the temperature is high, the driver sweats more, consumes more energy, and is prone to heatstroke. In order to prevent heatstroke, drivers should avoid spicy and greasy food, eat more fresh vegetables, drink more cool drinks, and pay attention to supplementing salt before and while driving.

5. Anti-fatigue and lethargy: The temperature is high in summer, the driver lacks sleep, and it is easy to be tired and sleepy when driving. Therefore, you should pay attention to rest before driving, ensure adequate sleep, try to use driving in the morning and evening, and avoid driving during habitual sleep time.

6. Anti-fuel air lock: The higher the temperature, the faster the fuel (especially gasoline) evaporates, and the easier it is to form an air lock in the oil circuit. Therefore, the fuel filter should be cleaned in time in summer to ensure the smooth oil circuit; Cover the fuel pump with a damp cloth when driving, and spray water regularly to keep it moist, so as to reduce the occurrence of air lock. Once there is air lock in the fuel system, stop immediately for cooling, and start the manual pump to add fuel to the oil circuit.

7. Prevention of brake failure: Brake fluid is easy to evaporate in high temperature environment, forming an air lock in the brake pipeline, and the brake shoe is easy to be ablated, resulting in brake failure. Therefore, the brake system should be inspected and adjusted in summer, brake fluid should be added or replaced in time, and the air in the hydraulic brake system should be exhausted to ensure that the brake cup, brake hose and brake shoe are in good condition.

Eight. Anti-poor lubrication: when the temperature is high, the viscosity of engine oil decreases and the oxidation resistance becomes worse, resulting in poor lubrication. Therefore, high-grade engine oil (such as E-CA40) should be replaced in summer, and the oil quantity and quality should be checked frequently, and added or replaced in time.

9. Anti-engine deflagration: Engine deflagration caused by overheating will increase the wear of the upper part of the cylinder by 3 ~ 5 times.

10. Prevention of distress on the way: the weather is hot, the road surface is dusty, the adhesion coefficient decreases, and the asphalt pavement becomes soft in the sun. When braking, the asphalt on the surface sticks to the wheel and is exposed, which reduces the braking performance. Drivers should drive carefully. At night, you should also pay attention to people sleeping in the shade of roadside and bridge head to prevent bumping. When crossing the road paved with crops, slow down and do not use the brakes easily to prevent side slip; Don't touch the pile of crops and utensils, or someone will rest in it. And pay attention to prevent someone from suddenly crossing the road from the crops; After passing, you should also stop to check whether there are crops on the engine oil and exhaust pipe.

Precautions for driving in hot weather

With the scorching sun and rising temperature, the range of high temperature area in China is getting bigger and bigger. When driving in strong sunlight, eyes often feel tired, and a lot of physical input and strong sunlight will lead to poor working conditions of drivers. The high temperature is irritating. In the closed environment of the carriage, once people are upset, it will lead to inattention when driving, and it is difficult to avoid dangerous situations. So be careful everywhere.

1. Driving without fatigue.

When the temperature is high in summer, the metabolic rate of human body is higher than usual, which leads to greater physical consumption. Especially in the summer afternoon, it is easy to feel tired and sleepy. Because drivers need a lot of concentration when driving, they are particularly prone to fatigue at this time. If he keeps driving, even if he is tired of driving, he will easily cause traffic accidents. Therefore, Li Wenxuan reminded everyone that in order to ensure adequate rest time, if you feel sleepy while driving, you should stop in time, have a proper rest, and then continue driving after your head is clear.

In addition, hot weather can also lead to irritability. Therefore, car owners and friends should never drive angry cars. They should always keep calm and obey the traffic rules.

2. Be sure to check the tire pressure.

With the gradual increase of air temperature and road surface temperature, the tire pressure is easy to rise when driving at high speed or long distance, leading to tire puncture. Therefore, Li Wenxuan once again reminds everyone that it is necessary to stop frequently for the sake of safety.

Be extra careful when driving.

In hot weather, people like to use umbrellas to keep out the sun, but in order to keep out the sun, the height of umbrellas is generally low, which will block the view of umbrella holders. Therefore, drivers must be extra careful when driving, especially when overtaking or turning.

You shouldn't wear dark sunglasses.

The dark color of sunglasses will delay the time for eyes to send images to the brain, resulting in speed perception distortion and making drivers wearing sunglasses make wrong judgments. Research shows that dark sunglasses can prolong the driver's emergency response time 100 milliseconds and increase the emergency braking distance by 2.2 meters.

5. Beware of spontaneous combustion

There are several spontaneous combustion accidents every summer. Therefore, before going out, you must check whether the high and low voltage lines of the vehicle are short-circuited or aging, whether the plug is loose, whether the battery is in normal working condition, and whether the oil circuit leaks oil. In addition, flammable and explosive articles such as gas lighters should also be cleaned up in time. Fire extinguishers should be equipped in the car, and the operation methods should be mastered to prevent accidents. In addition, it is also a good idea to insure the insurance company against spontaneous combustion loss.

6. It is not advisable to open the space for a long time.

When the engine is idling, incomplete combustion of gasoline will produce carbon monoxide. 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, which drastically reduced the oxygen in the car. Therefore, it is necessary to adjust the idle working state properly, or open the window for air every once in a while.

At this time, if a large number of cold drinks such as ice cream are ingested, the gastrointestinal blood vessels will suddenly contract and the blood flow will decrease, which will often cause physiological dysfunction, affect the digestion of food, and cause gastrointestinal diseases such as stomach pain and diarrhea.

7. Don't drive in slippers.

Female friends like to wear slippers in summer, which are not only beautiful, but also convenient and cool. Some people even drive in slippers. In fact, this practice is very dangerous. In an emergency, if the slippers don't keep up with the feet when stepping on the accelerator or braking, it is likely to delay the braking opportunity and cause traffic accidents. Li Wenxuan suggested that female car owners can prepare a pair of flat shoes for driving, which is both beautiful and safe.

8. Gas lighters should not be used.

The heat wave is rolling in midsummer, and some drivers have the habit of smoking to relieve fatigue. After the cigarette is lit, the gas lighter is usually conveniently placed on the dashboard. This is very dangerous. The plastic container of disposable gas lighter is filled with liquefied gas, which will expand when the temperature exceeds 40℃. The plastic shell will explode when heated. Although the explosive power of the gas lighter is not great, once the gas lighter is put together with some oil and combustible materials in the car, it is easy to cause a fire and the consequences are unimaginable. Therefore, drivers should not use gas lighters in hot summer. Besides, smoking is not allowed while driving.

9. Don't drink too many cold drinks.

In hot summer, drivers sweat a lot, are often upset and thirsty, and often want to eat cold drinks. But some people eat a lot, so overeating is not good for their health. Because when the driver drives, most of the blood will flow into the active muscles, thus providing enough nutrition and taking away the waste, thus temporarily reducing the blood supply of the gastrointestinal tract.

How to cool down and quench your thirst when driving in summer? Drinking cold drinks in summer is better than drinking hot tea. Drinking hot tea can dilate capillaries, open sweat pores, relax sweat glands and sweat freely, which is beneficial to heat dissipation in the body. Moreover, theophylline in tea also has diuretic effect, which can increase urination and take away some calories.
