Precautions for driving in hot weather

In the continuous high temperature weather, cars are easy to catch fire, which leads to the "boiling" spontaneous combustion of water tanks, which is a great burden to both motor vehicles and drivers. So be very careful when driving in hot weather, and don't drive too much. So what should I pay attention to when driving in hot weather?

First, prevent the body from overheating.

In summer, when the ambient temperature is high, the engine tends to overheat. 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 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.

Third, prevent the battery from losing water.

When the temperature is high in summer, the water in the battery electrolyte evaporates quickly, the liquid level drops quickly, and even the electrode plate is exposed under the liquid level, resulting in "water shortage" of the battery and early damage. Therefore, the liquid level in the battery should be checked frequently in summer, and distilled water should be replenished in time.

Fourth, prevent brake failure.

Brake fluid is easy to evaporate in high temperature environment, forming air resistance in 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.

Five, to prevent tire burst

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.

Six, to prevent 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.

Seven, 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.

Eight, to prevent engine deflagration

The explosion of the engine due to overheating will increase the wear of the upper part of the cylinder by 3 to 5 times.

Nine, anti-fatigue and drowsiness

In summer, the temperature is high, drivers lack sleep, and it is easy to get tired and doze off when 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.

X. preventing distress on the way

The weather is hot, there is more dust on the pavement, the adhesion coefficient decreases, and the asphalt pavement softens 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, beware of someone resting in the meantime, and pay attention to prevent someone from suddenly crossing the road from the piled crops. After passing, stop to check whether there are crops on the fuel and exhaust pipe.

When driving in hot weather, the most important thing to remember is to keep enough sleep, because people are easy to get sleepy in hot weather. When you are sleepy, that is, when the accident happens, remember to drive tired.
