How high can the temperature inside the car be in summer?

How high can the temperature inside the car be in summer? When driving on the road in summer, it is inevitable that the temperature will be high. Hot summer will always do all kinds of harm to cars, so we need to be vigilant. Let's share how high the temperature inside the car can be in summer.

How high can the temperature inside the car be in summer? 1 1. If the car is exposed to the sun at 40℃ outdoors for a long time, the temperature inside the car will reach more than 70 degrees.

2. When parking, try to stop in the shade with shelter and direct sunlight;

3. When the temperature inside the car is high, you can open the door before getting on the bus, spray water into the car, and then turn on the air conditioner to cool down.

The methods of cooling the car are:

1, the use of coolant. The main component of the coolant is dry ice, and the cooling effect is also very good. Opening the car door and spraying water 1 minute is not a problem at all.

2. Open inclined windows or three windows for ventilation. When it comes to window ventilation, many people's first reaction is to open all the windows. I don't know that the heat dissipation effect is not very good. The correct way is to open the inclined window or close the single-sided window to open other windows, so that the heat dissipation effect is better.

How high can the temperature inside the car be in summer? 2 car maintenance taboos.

First, avoid running the engine for a long time in an unventilated garage.

The exhaust gas from the engine contains carbon monoxide, which is an invisible and odorless poisonous gas. Long-term exposure to low-concentration carbon monoxide gas will cause headache, shortness of breath, nausea and vomiting, physical weakness and dizziness, psychological confusion and even brain damage. If Shitai Lexus starts the engine in the garage, it should open the garage door or open the exhaust device to exhaust the exhaust gas in the garage at any time. Don't stay near the exhaust pipe of the working engine for a long time, even if you work in the open air.

Second, avoid using oral straws.

Gasoline is not only flammable and explosive, but also toxic. Especially leaded gasoline, will damage people's nervous system, digestive tract and kidneys. In addition, gasoline also contains high concentrations of sulfides. Because hydrogen sulfide is also toxic, if you inhale gasoline, it will lead to poisoning or death. In case of inhalation, force yourself to vomit and go to the hospital for treatment in time.

Third, avoid contact with carburetor cleaner.

Carburetor cleaning agents mostly contain methyl chloride, aromatic hydrocarbons and ethanol, which are toxic to some extent, so it is very dangerous for these substances to be inhaled into the nose or splashed on the skin and eyes.

Fourth, avoid mechanical injury.

The maintenance of a car is related to all aspects. When maintaining cars, Shitai Lexus should set up obvious operation signs to prevent others from being hurt by' misoperation'. When starting a car, pay attention to the gear of the transmission to prevent misoperation and personal injury. When working under the hood, others should be allowed to leave the cab to prevent the engine from suddenly turning or others operating the mechanism, resulting in accidental injuries.

If Shitai Lexus 4s shop needs to work under the car, it should set up obvious signs and cover the car with a wooden cover. When a car is supported by a jack, the jack should be placed stably. Driving tools (driving bench) should be prepared before driving, and fragile items such as bricks are prohibited. Do not test screw holes, lock holes, etc. when installing components. Avoid breaking your fingers with your hands. Don't work under the car when testing the engine.

Five, to avoid fire

When maintaining cars, it is often necessary to use flammable and explosive materials such as oil and cleaning agents. Don't forget the fire-fighting measures at this time, and prepare a fire extinguisher just in case. Steyr Lexus is near the fuel tank and battery. Don't smoke, because the combustible gas escaping from the fuel tank and the hydrogen escaping from the battery can be easily ignited.

Sixth, avoid burns

The engine that has just turned off must be handled carefully to prevent burns caused by relatively high temperatures in various parts of the engine (water tank, exhaust pipe, power steering fluid tank, spark plug, etc.). ). If the engine temperature is high, do not remove the water tank cover or loosen the drain switch to prevent burns.

7. Avoid damaging the car.

Brake fluid is harmful to automobile paint film (including leather shoes paint film) and can quickly dissolve paint film. Brake fluid is harmful to eyes. If it spills into eyes, it must be washed with clear water immediately.

Eight, avoid careless protection of rotating parts and automobile road test.

When the engine is running, be careful that your hands, clothes and tools must leave the rotating fan and fan drive belt (it is best to take off the ring, watch, tie and other items). When Shitai Lexus does a good test run, all parts of the car should ensure safe parking and effective steering. Road test vehicles must have obvious test marks. During the test run, personnel must ride safely and on the special test run track.

Nine, avoid not paying attention to the cleanliness of the workplace

When closing the engine cover or other assembly covers, check whether tools, rags, removed parts and other items are forgotten, and then close them after confirmation.

How high can the temperature inside the car be in summer? Three reasons:

1. Long-term exposure to the sun will lead to the aging of rubber products (such as door sealing strips and tires), and it may also lead to water leakage when it rains.

2, high temperature exposure will lead to glass breakage. After the glass is exposed to strong sunlight for a long time, the temperature will rise sharply and its physical properties will change. If you wash the glass with cold water, it is easy to break or damage its performance.

If the car is exposed to high temperature for a long time, the formaldehyde in the car will exceed the standard, and the formaldehyde index may even be three times higher than usual.

How to solve:

1, open and close the door

The hot air in the car has been lingering, mainly because the hot air in the car has not circulated. We can lower the temperature by opening and closing the door. This method is the simplest and most practical. First roll down the window of the cab door, and then repeatedly open and close the door 10 times at the position of the auxiliary cab. Within two minutes, the temperature inside the car will drop by nearly 10 degrees Celsius.

Its principle is similar to air conditioning. Because the hot air floats on the cold air, opening and closing the door introduces a lot of cold air lower than the hot air inside the car, and repeats it for ten times to strengthen the air circulation inside and outside the car, so that the hot air can be discharged quickly and the cooling speed is very fast.

2. Mix alcohol and water to cool down.

Alcohol and water absorb heat, so we can prepare a sprinkler, fill it with 3/4 water, pour in about 20 ml of alcohol (not too much), spray it quickly in the car after opening the car door, and then close the car door without opening the window. After a minute or two, the temperature inside the car will drop, and it will be much more comfortable to sit in the car.

Don't worry that spraying alcohol into the car will leave an odor, because the alcohol concentration is low, so the smell of alcohol will be eliminated in a few minutes. In addition, the ignition point of 100% pure alcohol is 75℃, and the lower the concentration, the higher the ignition point. When 75% medical alcohol is mixed with water at the ratio of 1: 10, it will not catch fire.

3, sunshade curtain

Sun protection for cars not only requires attention when parking, but also how to do sun protection for cars when driving, especially in the position near the window. Really getting sunburned is a kind of torture for drivers and passengers, and it will also damage the interior of the car.

In this way, we can put a parasol on the car, which can not only protect the sun and cool down, but also protect the privacy inside the car. The installation is simple for a few seconds, and the front windshield can be prepared, so that we can also use it to shade and cool down when parking.

4, car paint coating

It's too hot to leave the window open. If the journey is short, it can last for a while. But if the distance is long, it will be very uncomfortable in the car. Generally speaking, protecting the exterior of a car in summer means waxing. That is to say, paint the car with a layer of polymer structure paint containing ultraviolet reflector to reduce the damage of direct sunlight to the car.

In fact, there are many paint holes in the paint of cars. After waxing and painting, it is necessary not only to completely fill the paint holes invisible to the naked eye, but also to form a transparent "protective coating" on the paint surface of the car to achieve the purpose of shading. Protect paint and cool cars.

5, car clothes

Although we can park our car in the shade, we don't always have the luck. Even if we park our car in the shade, we can't stop the wind and dust, so it's a good choice to prepare a sunshade coat for our car. It can block ultraviolet rays and prevent the surface of the car from being exposed to the sun.

The car clothes are very reflective, which can block 80% strong light and will not feel burning when entering the car. It can also effectively prevent the damage of rain, frost, wind and dust to the car. Whether it is summer or winter, car clothes are a good helper for cars.

How high can the temperature inside the car be in summer? 1. What are the hazards of hot weather to cars?

There are many hazards to cars caused by high temperature weather, such as changes in car paint, engine problems, non-refrigeration of car air conditioners, oil system problems, unstable battery voltage, flat tires at high temperature, and easy aging of interiors at high temperature.

Second, how to maintain the car in hot weather

1, paint protection cannot be ignored.

Generally, car owners mention car maintenance, usually replacing consumables such as three filters and engine oil. In fact, the most important thing to love a car at high temperature in summer is

Protect the car paint. Car paint is like ten thousand clothes we wear in Qian Qian. It is the face of men and women! The issue of face is always the most important.

Therefore, before the big sun in summer and the occasional thunderstorm kill the car paint, you should put some energy into washing the car often and waxing it regularly, but if you want to wash your car yourself, don't choose to wash it at noon when the sun is maximum, but wash it in the early morning or evening. If the money is not bad, I suggest that you can also make a higher-end atmospheric paint surface for sealing or coating, giving the car paint a sense of security!

If the paint surface is "injured", it can't be ignored. Scratches and dents in car paint must be repaired in time to avoid "harm to nature"!

2. Cleanliness is the first priority.

It is very important to clean the car when it is hot every day in summer. You should always open the window for ventilation and clean the outside and inside of the car regularly. You can scrub yourself with disinfectant when cleaning. If you have time, you can also go to a special maintenance shop for ultraviolet irradiation or high-temperature disinfection and sterilization. However, it must be noted that the air disinfection in the car is carried out when there is no one in the car. After disinfection, open the window for ventilation for 5 ~ 6 min, wipe the facilities in the carriage with water, and then dry them with clean cotton cloth to remove the residual disinfectant.

3, the use of air conditioning has a knack.

In summer, the temperature inside the car is often very high. So, don't turn on the air conditioner immediately when the car starts. It will be better to open all the windows for 3-5 minutes before turning on the air conditioner. If the engine is under heavy load for a long time, the air conditioner should be temporarily turned off. When cooling, it is best to blow the wind direction of the air conditioner upward, because the cold air will sink, and the wind direction file is best to choose the blowing face file, and the air outlet is best to adjust upward.

Finally, pay attention to turn off the air conditioner before reaching the destination to reduce the odor. If it rains during driving, the window will fog easily. You can also blow the cold air of the air conditioner to the glass to disperse the fog.

Take care of the four feet of your car.

Whether it is a person or a car, if the foot is not good, it is basically useless. No matter where the road is in summer, it is estimated that an egg will be cooked soon. At this temperature, more attention should be paid to the inspection and maintenance of tires. Tire inspection, if the pattern is worn, it is necessary to replace it with a new tire. At the same time, speeding, overloading or emergency braking are easy to cause tire puncture. Therefore, the tire pressure can be reduced appropriately, or helium gas with more stable physical properties and less expansion can be filled into the tire.

5. Prevent the car from spontaneous combustion.

The news of car spontaneous combustion is indispensable in common traffic accidents in summer, and car owners should also pay attention to prevention. Circuit failure and engine room oil pollution are the main culprits of spontaneous combustion. The main measures to prevent spontaneous combustion are: don't arbitrarily change the circuit to increase the power load, and often check the circuit oil circuit to prevent oil and electricity leakage-once the car is found lying on the ground in the morning,

There is oil stain, petrol smell, burnt rubber smell, etc. You must not be careless. You must check the cause and troubleshoot immediately.

6, brake inspection cannot be less.

There are many rainy days in summer. At this time, braking performance is very important. If the brakes don't work, it is likely to slip out of control on the slippery road after the rain, which is always very dangerous. Therefore, it is necessary for car owners to do their homework at ordinary times and check the brake system more.

7. High temperature will accelerate the evaporation of oil and water.

When the temperature is high, the oil and water in the car are easy to evaporate. Therefore, the owner must cover the box cover, the water level in the water tank, the oil level of the engine oil and the height of the electrolyte in the battery. Where there is liquid, check it frequently and add it in time to avoid potential safety hazards.

During the operation of the vehicle, many parts are constantly worn, and the daily maintenance and inspection scope is far from limited to three filters, engine oil, brake pads, spark plugs and so on. And car maintenance is not limited to summer. Many times, if you don't check and maintain your car at ordinary times, unexpected faults may occur, so take precautions!
