How to drive safely in summer

Five points to prevent car "heat stroke"

Point 1: Clean air conditioner

Due to the high temperature and high humidity in summer, the surface of the air conditioner evaporator is more prone to breed microorganisms. If the air output is normal, do a disassembly-free cleaning. If the air volume is not enough, disassemble and wash it; after turning on the air conditioner for a while, observe whether there is condensation water flowing out of the car. If not, you must check the dredging, otherwise, the condensate will flow into the car, which will cause serious corrosion and mildew inside the car.

Point 2: Stick to antifreeze

Don't believe that some people do not need to use antifreeze in summer. The boiling point of antifreeze is much higher than that of water, and it is more suitable for use at high temperatures. After the water evaporates, it is easy to form scale in the water tank and the engine water channel, which affects the heat dissipation. When you see that the antifreeze is insufficient, you cannot mix different types of antifreeze.

Point 3: Check the route in the car

In summer, the external temperature of the car is high, especially some cars in poor condition are more prone to spontaneous combustion. Check the lines in the vehicle (especially circuits, oil circuits, etc.) for aging, damage, or bareness, to prevent the generation of electrical sparks, especially for vehicles that have changed the line; check for leaks, dust, and other debris in each component and pipeline , Should be cleaned up in time to reduce hidden dangers.

Point 4: Tires are filled with nitrogen

For tires with the same air pressure, after high-speed driving in summer for a long time, the air-filled air is about 0.3 atmospheres higher than the air pressure of nitrogen-filled air, and the nitrogen pressure can also reduce the temperature of the tire, ensure the stability of the tire pressure, reduce the chance of flat tires, and reduce driving noise.

Point 5: Protect the paint

The temperature in summer is high, after the vehicle is cleaned, it should be dried immediately, rather than dry to avoid the acid and alkali in the water corroding the paint surface; in addition, in the city, the erosion of acid rain will also seriously damage the finish of the paint surface, after the rain , Be sure to flush the vehicle in time. Normally park the vehicle as much as possible not to be exposed to the sun. If possible, cover the car cover at any time to prevent rain, dust and sunlight.

The four main reasons for the car to get on fire

Electric leakage: When the engine is working, the temperature of the ignition coil is very high, so that the insulation layer of the high-voltage ignition wire is softened, aging, and cracked. The ignition high-voltage electricity can easily break through the insulation layer, and it is easy to produce high-voltage electric leakage, causing continuous temperature leakage. Elevated, igniting the gasoline leaked from the engine, carburetor, etc., causing a fire.

Grounding: In spontaneous combustion accidents caused by line faults, the main reason is grounding. Many users of new car purchases love the car they just purchased. They may add anti-theft devices to the car, change high-end audio, improve the shape, and may also add air conditioning. These actions may be the cause of the grounding of the wires, and also one of the reasons for the spontaneous combustion of the car.

Oil leakage: The leaked gasoline is the most terrible flammable substance, it is very important to prevent fuel leakage.

Electrical appliance failure and short circuit: common starter switches are welded due to contact sintering, and the starter magnetic switch cannot be released, causing the starter to start for a long time (the starter's safe start time is 5 seconds), causing the starter to heat up and catch fire.

Prevention: Comprehensive inspection will not put flammable products
