What should I pay attention to when driving in hot weather?

In hot weather, cars are prone to breakdown and even accidents. The following are the precautions I shared when driving in hot weather. Let's have a look.

Precautions for driving in hot weather 1. Prevent the engine from overheating: in summer, the environment temperature is high, and 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 causes the water in the battery electrolyte to evaporate rapidly, the liquid level drops rapidly, and even the electrode plate is exposed to the liquid level, resulting in the battery? Water shortage? And early injury. Therefore, the liquid level in the battery should be checked frequently in summer, and distilled water should be replenished in time.

Third, prevent tire puncture: In summer, the air pressure in locomotive tires will increase with the increase of temperature, which is easy to cause tire puncture accidents. 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 sunshine is strong, the temperature is high, the driver sweats more, 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.

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

6. Fuel gas resistance: The higher the temperature, the faster the fuel (especially gasoline) evaporates, and the easier it is to form gas resistance in the oil circuit. Therefore, the fuel filter should be cleaned in time in summer to ensure the smooth oil circuit; When driving, cover a wet cloth on the fuel pump and spray water regularly to keep it moist and reduce the generation of air resistance. Once there is air resistance in the fuel system, immediately stop cooling, pull the manual oil pump and inject fuel into the oil circuit.

Seven. Prevention of brake failure: Brake fluid is easy to evaporate and vaporize in high temperature environment, forming air resistance in the brake pipeline, and brake shoes are also easy to be ablated, resulting in brake failure. Therefore, the brake system should be checked and adjusted in summer, brake fluid should be added or replaced in time, the air in the hydraulic brake system should be exhausted, and the brake cups, brake hoses and brake shoes should be kept 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, switch to advanced engine oil (such as E-CA40) in summer, check the oil quality regularly and add or replace it in time.

9. Anti-engine deflagration: the engine deflagrates due to overheating, which will increase the wear of the upper part of the cylinder by 3 to 5 times.

X. prevention of distress on the way: the weather is hot, the road surface is dusty, the adhesion coefficient decreases, and the asphalt asphalt pavement becomes soft under the sun exposure. 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 cool by the roadside and at the bridge head to prevent collisions. When crossing the road covered with crops, slow down and don't use the brakes easily to prevent side slip; Don't touch the piled crops and utensils, lest someone have a rest; And pay attention to prevent someone from suddenly crossing the road from the crop pile; After passing, you should also stop to check whether there are crops on the car oil and exhaust pipe.

Tips for driving in hot weather 1, pay attention to signs of spontaneous combustion such as peculiar smell and abnormal sound.

Old vehicles with a service life of more than four or five years will have hidden dangers of spontaneous combustion. The car mainly pays attention to regular inspection to see if there are aging oil pipes and wires. , exposed wires or oil leakage. Car owners should pay attention to the signs of vehicle spontaneous combustion when driving, such as peculiar smell, abnormal sound or vehicle electrical failure. If the vehicle spontaneously ignites, you should immediately pull over to a place with few people, turn off the fire, take out the fire extinguisher, find the fire point, and cool the fuel tank and the burning part to prevent explosion.

2. Stop to cool down when the water temperature is high

High water temperature is a common phenomenon of vehicles in hot weather. Please turn off the air conditioning system before turning off the engine and starting it. When driving, if you find that the thermometer pointer is close to the red line, you should slow down as soon as possible and park your car in a cool place. In order to avoid damaging the engine, do not turn off the engine immediately after parking, but let the engine run at idle speed for a period of time. If the water temperature doesn't drop, you should turn off the car and check the engine coolant. But be careful not to open the water tank cover immediately, otherwise it will be easily scalded by steam.

3. Brake slowly after a flat tire

In hot weather, we should pay special attention not to let the tires collide with obstacles such as road teeth, because it is easy to hurt the tire sidewall and cause hidden dangers. If a flat tire occurs during driving, the driver should tightly control the steering wheel with his hands and brake slowly, so that the vehicle can slow down and stop smoothly. Never brake suddenly, because it will easily lead to tail flick or even rollover.

Precautions for driving in hot weather to prevent accidents; Beware of spontaneous combustion at high temperature in summer.

There are some spontaneous combustion accidents every summer. So as a car owner, how to prevent car spontaneous combustion?

"Inflammable and explosive articles such as perfume and gas lighters in the car must be cleaned up in time." The police of the city traffic police brigade told the author that these flammable and explosive materials are prone to fire or explosion when they encounter high temperature.

Generally speaking, spontaneous combustion is related to line aging and oil leakage, so it is necessary to check whether the high and low voltage lines of vehicles are short-circuited or aging and whether there is oil leakage in summer. The daily maintenance of the car is the key, and it is necessary to do regular maintenance.

"In summer, a flat tire is also a traffic safety hazard." According to the traffic police, with the gradual increase of temperature and road surface temperature, the tire pressure is easy to rise when driving at high speed or long distance, resulting in a flat tire. When driving at high temperature and high speed, please remember to stop and step on it in time for safety reasons.

Wearing sunglasses while driving should be of excellent quality.

"In summer, the sun is shining directly, and the strong light is easy to make people hard to open their eyes. Many drivers like to wear sunglasses to drive. " The traffic police suggested that you can wear sunglasses, but you should choose light-colored sunglasses.

It is understood that the dark color of sunglasses will delay the time for eyes to send images to the brain, leading to "poor vision" and "vision error", especially when encountering traffic lights, traffic lights and obstacles. This visual delay will also distort the sense of speed and distance, which will make drivers wearing sunglasses make wrong judgments. In case of unexpected events, they will not respond in time, which may easily lead to traffic accidents.

Wearing slippers to cool down is also prone to accidents.

On a hot day, everyone likes to wear cool summer clothes, and many drivers even like to put on slippers to drive, in order to be convenient and cool. "It's dangerous to drive in slippers, which is against traffic regulations and is not allowed," said Suong Chen, a policeman of the Municipal Traffic Police Brigade.

Because slippers are easily hooked by brake pads and leave the soles of feet, in an emergency, if slippers slip easily when stepping on the accelerator or braking, it is likely to delay the braking opportunity and lead to traffic accidents.

"It is best to prepare a pair of flat shoes in the car." Suong Chen said, wear flat shoes when driving, and then put on your favorite shoes after getting off the bus.

Put an end to drunk driving without fatigue

There are many people who drink beer at high temperature to prevent heatstroke, especially those who eat supper at night. Most people think that drinking some cold beer can relieve the sultry feeling caused by hot weather. Relatively speaking, drunk driving is also easy to happen in summer.

"Never drink and drive." Suong Chen said that drunk driving is a serious traffic violation, which can easily lead to traffic accidents. This year, the municipal traffic police department also launched a "zero action" against drunk driving at night, and it has become a routine to rectify drunk driving violations.

In addition, the temperature is high in summer, and physical exertion is relatively large, especially at noon, which makes it easy to doze off. Please pay attention to drivers and friends, be sure to have a good rest, ensure adequate sleep and abundant physical strength, and don't drive tired. If you feel sleepy, you can find a safe and cool place to park and rest, and then continue driving when your mind is clear.

Stay away from "traffic jam irritability"

"Can you drive?" "Can't I go first?" "It's blocked again!" During the morning and evening rush hours, there are many such complaints in the long queues.

"It's hot in summer, which makes people fidgety. Please keep a good attitude among car owners. " Suong Chen said that "traffic psychological irritability" is caused by physical fatigue on the one hand, and traffic conditions and pedestrians' illegal behaviors on the other.
