Wrong common sense of using cars

1. What common sense about cars is wrong?

1, the higher the speed, the more fuel consumption.

Wrong, in fact, the average car is the most fuel-efficient at 2000-3000 rpm, and it is more fuel-efficient below the most fuel-efficient speed. 2. The greater the displacement, the more oil is wasted, which is only in some cases.

3. Manual transmission is more fuel-efficient than automatic transmission, and now automatic transmission is "very smart". 4. Turbocharging is more fuel efficient than naturally aspirated engine, which is not necessarily the case.

5. Germany and the United States consume oil, while Japan and South Korea save oil. You will find that German cars are actually very fuel-efficient. 6. The heavier the car, the safer it is. The heavier the car, the easier it is to break through the handling limit, and the inertia braking performance is also reduced.

7. The sedan is safer than the hatchback, depending on the structure. A hatchback is not necessarily safer than a hatchback. Some hatchbacks often strengthen the tail and are more "crash-resistant" than hatchbacks.

2. What are the wrong car maintenance methods?

1, Too much oil fault When the oil in the engine oil pan is insufficient, the friction between the bearing and the journal will be poorly lubricated due to the small amount of oil, which will aggravate the wear degree and even lead to the burning accident of the tile shaft.

However, if there is too much oil, the crank handle and the big end of the connecting rod will be violently stirred when the engine is working, which not only increases the internal power loss of the engine, but also increases the amount of oil splashed on the cylinder wall, resulting in the failure of engine oil combustion. Therefore, the oil in the engine oil pan should be controlled between the upper and lower score lines of the dipstick.

2, waxing in circles Many people habitually wax the car body in a circular way, which is not the correct method. The correct way to wax is to do it in a straight line, alternately horizontally and vertically, and then wax it finally according to the direction of rainwater flow, which can reduce the concentric rings on the surface of car paint.

3. 12 What are the wrong vehicle maintenance methods?

Many private car owners like to wash their cars in the hot sun, thinking that they can quickly dry the water after washing.

It's actually wrong. When washing a car in the hot sun, the convex lens effect formed by water droplets will cause local high temperature on the top layer of car paint. After a long time, the paint will lose its luster. If you wax at this time, it is easy to cause uneven color of the car body.

Therefore, it is best to wash the car and wax it under cover. If you can't guarantee it, you'd better choose cloudy or sunny morning and evening. Washing a car is like taking a bath-in summer, the air conditioning temperature rises, the dust increases, the car body is easy to get dirty, and the frequency of car washing by car owners begins to rise. Many car owners want to wash their cars as thoroughly as bathing themselves.

However, it should be noted here that the appearance of automobile air conditioners must be kept dry. If the car air conditioner is accidentally wet, it will affect the life of the car air conditioner. Wax a circle-the effect is poor. Many people habitually wax and circle the car body, which is not the right method.

The correct way of waxing is to do it in a straight line, alternating vertically and horizontally, and then take the last line along the direction of rainwater flow, which can reduce the concentric rings on the surface of car paint. Too much oil-easy to break when the oil in the engine oil pan is insufficient, the friction between the bearing and the journal will be poorly lubricated due to the small amount of oil, which will aggravate the degree of wear and even cause an accident of burning the bearing shaft.

However, if there is too much oil, the crank handle and the big end of the connecting rod will be violently stirred when the engine is working, which not only increases the internal power loss of the engine, but also increases the amount of oil splashed on the cylinder wall, resulting in the failure of engine oil combustion. Therefore, the oil in the engine oil pan should be controlled between the upper and lower score lines of the dipstick.

The bolts are too tight-there are many fasteners connected by bolts and nuts on the permanently deformed car. We should ensure that they have sufficient pre-tightening force, but they should not be screwed too tightly. If it is screwed too tightly, on the one hand, the connector will be permanently deformed under the action of external force; On the other hand, the bolt will be permanently deformed due to stretching, the pre-tightening force will be reduced, and even it will slip or break.

The fan belt is too tight-the bearing load is heavy and the temperature is too high in summer. Some drivers think that increasing the tightness of the fan belt can improve the cooling effect of the engine, so they keep increasing the tightness of the fan belt, which leads to the fan belt being too tight, but I don't know that this is wrong. Keep the fan belt tight, because too tight will lead to excessive bearing load, wear and increase power consumption, and at the same time bend the pump shaft, lengthen and deform the belt, and shorten the service life.

Imported tires-not necessarily applicable. Some people especially like to emphasize "import" when buying tires. The new tires imported from abroad have one of the most fatal defects for domestic users, that is, they are not applicable.

The flat roads in Europe are quite different from those in Beijing's Second and Third Ring Roads. It is difficult for tires suitable for European road conditions to perform well in Beijing, especially the impact resistance of the sidewalls is obviously unacceptable, just like walking on the gravel road wearing Italian brand-name leather shoes, and the sidewalls are bound. After joint venture production in China, some foreign brands added a layer of curtain cloth on the sidewall according to the domestic road conditions, which greatly enhanced the impact resistance of the sidewall. The tires produced by the joint venture can completely replace imported goods in performance.

The new battery does not charge-the first charge of the battery is called the first charge, which has a great influence on the service life of the battery. If it is not charged, that is, it is directly used with "water", the battery capacity is not high and its life will be shortened; If you charge directly, it will also shorten your life.

Usually, the initial charging of the battery is after the electrolyte is filled, and it can be installed and used by charging with a small current of about 1 hour. Equipment in the car is added at will-affecting driving safety. Private car is the owner's mobile home, and it is understandable to pursue comfort and luxury. However, some car owners add various devices to their cars. If this modification is not handled properly, it will often have an adverse impact on the performance and handling of the car, and it is easy to leave sequelae or affect driving safety.

The cooling water temperature is too low-it is very hot when the engine wears out in summer. Some drivers blindly require the cooling water temperature to be as low as possible to prevent the engine temperature from being too high, and some drivers simply remove the thermostat to achieve the purpose of cooling down. These practices are all wrong. Automobile engines are afraid of both heat and cold. If the cooling water temperature is too low, it will worsen fuel combustion, increase engine oil consumption, aggravate wear, increase engine oil viscosity and reduce engine power.

The test shows that when the cooling water temperature is 40-50℃, the engine wear increases by 60%-80%, the power decreases by 25% and the fuel consumption increases by 8%- 10%. Therefore, the temperature of engine cooling water is not as low as possible, and should generally be controlled between 80-90 degrees Celsius.

When the water tank "boils", the water is added quickly-the cylinder is cracked. It is very hot in summer. Some drivers saw the phenomenon of "boiling" in the water tank and worried that the engine temperature would rise again, so they immediately turned off the engine and added water. This practice is wrong, and it is very likely that the cylinder head will crack due to quenching.

When the water tank "boils", the general correct method is: stop immediately, keep the engine idling and continue to dissipate heat; At the same time, open the range hood to improve the heat dissipation speed. After the cooling water temperature drops, turn off the engine.

At this time, if the amount of cooling water is insufficient, it should be added slowly to prevent the cylinder head from cracking due to sudden cooling. Don't use the car for a long time, and don't use the car for a short distance-some people have become car owners, but they are usually "unwilling" to drive and only drive out on holidays. In fact, this way of using a car is very harmful.

The surfaces of transmission parts such as engine and gearbox will rust due to frequent direct contact with air, and the long-term natural discharge of batteries will affect the service life. The best way is to run for 30 to 40 minutes every few days.

In addition, always using a short-distance car will also hurt the car. The car is moving at any time, but it is not far away, which is an important cause of car injuries. The parts on the car are most seriously worn during the engine start-up to the stable stage, and it takes about 20 minutes to make up the power consumed by starting the car battery once. This kind of car habit can easily make the car break down prematurely.

4. What are the common mistakes in car maintenance?

There are many mistakes in car maintenance and use. Some common sense mistakes are made not only by novices, but also by some old drivers. Some wrong practices in the process of automobile maintenance and use may not only damage the automobile itself, but also endanger the driving safety.

Myth 1: It is best to reduce tire pressure in summer. The temperature is high in summer. Some drivers are afraid that the tire will expand when heated, which will lead to high tire pressure and puncture. Some even artificially reduce the tire pressure. In fact, low tire pressure is more dangerous than high tire pressure.

When the tire pressure is too low, the contact area between the tire and the ground increases.

On the contrary, the temperature in the tire will rise rapidly when driving, and it is easy to puncture when driving too fast, which endangers driving safety. In addition, low tire pressure will cause tire deformation, increased wear and fuel consumption. Professional tire pressure measurement and maintaining normal tire pressure are particularly important in driving in summer.

Myth 2: The lower the engine cooling water temperature, the better. It is very hot in summer. Some drivers think that the lower the engine cooling water temperature, the better. In fact, low water temperature will damage the engine. Automobile engines are afraid of both heat and cold. If the cooling water temperature is too low, it will worsen fuel combustion, increase engine oil consumption, aggravate wear, increase engine oil viscosity and reduce engine power. Different types of engines may have different requirements for water temperature, and the key is to control it within a reasonable range.

Myth 3: The more oil, the better. When the oil in the engine oil pan is insufficient, the lubrication is insufficient, the friction is intensified and the engine is damaged; However, if there is too much oil, the engine will violently stir the crank and the big end of the connecting rod when working, which will make the engine unstable, and the oil splashed on the cylinder wall will increase, which will lead to poor oil combustion and discharge, and may also cause danger under certain circumstances. Therefore, the oil should be controlled between the high and low marks of the oil dipstick.

Myth 4: High-grade overtaking or high-grade climbing has smaller torque, slower throttle response, but slower acceleration. Overtaking at high speed is very dangerous. If overtaking is correct, you should slow down by one gear. In automatic transmission, just step on the accelerator to the end.

Climbing at high speed is also dangerous. When the vehicle is in a high gear and the accelerator is driving on a slope, the driving resistance of the vehicle is large, which makes the engine speed low, the disturbance of the mixture in the combustion chamber is small, and the flame triggered by the spark plug is slow, which makes the combustible mixture automatically deflagrate. Long-term strong deflagration will cause local overheating, melting and damage of related components, and may also cause excessive torque load of engine crankshaft pads and crankshaft, leading to malignant accidents such as tile burning and even crankshaft fracture.

Myth 5: Some people are afraid of braking flameout and develop the habit of stepping on the clutch before braking; Others think that braking will be more effective after cutting off the power supply, which is wrong. In any case, driving with the clutch on will increase the inertia of the car. After stepping on the clutch, the engine speed quickly drops to idle speed, the total vacuum degree of the intake pipe decreases, the auxiliary force of the vacuum booster is greatly reduced, the braking distance becomes longer, and the braking is weak. The correct way is to step on the brake first, and then step on the clutch when the bus stops soon.

Myth 6: When turning while braking, the center of gravity of the car moves outward under the action of centrifugal force. At this time, braking will aggravate the roll and cause unilateral braking. If you drive too fast or brake too hard, you are in danger of overturning. The correct way is to slow down before entering the corner and shift to a low gear. Add oil slowly after entering the corner to keep the car body stable. At the same time, when cornering, keep the principle of "slow in and fast out", bend from the big corner of the outer lane and straighten the corner as much as possible. Myth 7: Downhill neutral sliding is both fuel-efficient and convenient. The carburetor car can save fuel by neutral, and the EFI car can save fuel by sliding in high speed, but it costs fuel to stay in neutral.

It is quite dangerous to control the speed only by braking when sliding down the slope, especially on long slopes and steep slopes. Due to the long-term use of braking, the brake friction plate will overheat, the friction coefficient will decrease, and thermal recession will occur, which will lead to the decline or even failure of automobile braking performance. The correct way is to put a suitable gear according to the actual speed and let the engine brake. At the same time, it is very important to rely on gear braking when encountering steep slopes or winding roads.

Myth 8: Braking in water or driving in rainy days, the accelerator is suddenly released at high speed, and one side of the wheel suddenly hits the waterlogged road surface. Many people's first reaction is to step on the brakes, which makes it easy to slip. At this time, controlling the steering wheel is more important and safer than stepping on the brakes.

Driving on muddy roads in rainy days, suddenly stepping on the accelerator or suddenly releasing the accelerator will also cause sideslip. Because the car suddenly loosens the throttle when driving at high speed, it will cause the car to suddenly slow down, causing the wheels to brake with the ground instantly, thus causing side slip; On the contrary, sudden increase in speed is also prone to side slip. Therefore, it is necessary to drive at a low speed and control smoothly in rainy days.

Myth 9: It is safe to lock the central door lock while driving. Some people like to lock the central door lock as soon as they start the car. They think it is safe, but it is extremely dangerous. After the central door lock is locked, once the car has an accident, it can't be opened, and the accident rate is greatly improved. It is best not to lock the central door lock when driving normally, and then lock the central door lock when encountering traffic jams or waiting for traffic lights.

Myth 10: The stronger the high beam at night, the safer it is or the safer it is to turn on the fog light. The greater the illumination angle of the lamp, the safer it is. The higher the light, the brighter it will be, because it will affect the sight of oncoming cars.

Driving with fog lights at night is not only unsafe, but also dangerous. Especially, the white beam of the front fog lamp is very strong, which affects the safety of the opposite vehicle and itself. If the weather is bad, turn on the fog lights no matter day or night.

5. What are the misunderstandings of using cars in winter?

Mistake 1: Tighten the handbrake on rainy and snowy nights. At ordinary times, many people will pull the hand brake when parking to prevent the car from slipping.

But this seemingly safe action is not needed on rainy and snowy nights. Because there is usually snow water on the brake disc after driving in rainy and snowy days, the brake disc may freeze if you stop the hand brake at night.

Suggestion: If the owner stops for a long time on a rainy and snowy night, it is best to park the car on a flat road, hang the car in the gear, and find a bracket to fix the car, so as to avoid the brake disc from freezing. Mistake 2: Don't wash the car in time after the snow. Many friends are not very diligent in washing cars in winter, which is wrong.

Because there are usually corrosive components in snow, whether it is paint, chassis, wheels or tires, it will hurt to be covered with snow for a long time. If it is not cleaned in time, the gloss of car paint will be greatly reduced.

Therefore, the owner must wash the car in time after the snow, and don't delay. 0 suggestion: wash the car in time after snow, even if the weather forecast shows that it will snow in the next few days, don't delay washing the car.

As long as it is covered with snow, it should be washed away with clear water immediately. In addition, it is easy to pour clean water into the lock hole in the open air, because it is especially easy to freeze the lock core in the cold weather after snow.

Therefore, it is best to stick the keyhole with tape before washing the car to prevent water from entering. Mistake 3: Use white wine instead of antifreeze. Some car owners use white wine or alcohol instead of antifreeze in winter. In fact, it looks cheap and it is not cheap to use.

Wine is a flammable liquid, which easily produces alcohol vapor and is easy to catch fire. What is more troublesome is that the fire of wine cannot be put out with water, and ordinary foam is ineffective, so it must be put out with anti-solvent foam. In addition, alcohol is volatile, unstable in frost resistance and easy to boil with low boiling point. If you use alcohol and add a thermostat at 80℃, the result can be imagined.

Of course, it is ok to use it occasionally in an emergency. Suggestion: Use professional and qualified antifreeze, and the amount of antifreeze should be appropriate.

Check whether the engine cooling system leaks before adding antifreeze, and eliminate it in time before adding antifreeze. In addition, according to different regions and models, cars mainly choose antifreeze with different freezing points and models.

Mistake 4: The window freezes and is drenched with boiling water. Some car owners saw their cars covered with ice and snow. Their first thought is to give their car a hot bath to keep it away from the cold, but they don't know that this behavior will cause the windshield to explode and damage the paint of the car. Suggestion: The correct deicing method is to start the engine first, turn on the car warm air, and slowly remove the ice from the ice gap with a special ice shovel for car glass.

Mistake 5: Blindly start the wiper. The wiper on the car window is easy to freeze at night on rainy and snowy days, so the owner should check whether the wiper is frozen before driving in the morning on rainy and snowy days, and can't start the wiper blindly. If you go out and find that the wiper is stuck to the windshield by snow or frost, don't wash it directly with hot water, which will easily crack the window due to temperature change and cause the wiper to deform.

Suggestion: Before using the wiper in winter cold weather, check whether the wiper is frozen on the window. If you go out in the morning and find that the wiper sticks to the windshield due to snow or frost, you can turn the air conditioner into hot air and turn the blowing mode to the "windshield" position, and soon the wiper will turn on naturally.

In addition, if you stop for a long time when it snows, the wiper can stand up to prevent freezing. Mistake 6: The rain and snow road accelerates quickly and the brakes are urgent. In winter, the road surface is slippery in rainy and snowy weather, and the friction coefficient between the tire and the ground decreases, which increases the difficulty for drivers to control the vehicle. If the operation is improper, the vehicle will easily slip.

Suggestion: Don't jerk the clutch to accelerate when driving in the snow, and don't jerk the steering wheel. But driving at a constant speed to control the speed. When the vehicle needs to slow down, the method of downshifting can be adopted to make full use of engine braking.

Try to use emergency braking as little as possible, or use some braking. Mistake 7: You can install snow chains at will to deal with icy roads. In addition to winter car tires, it is also a good way to install a set of snow chains for your car.

Some car owners think that the snow chains can be installed on any wheel, and some car owners find it strange to see the snow chains of street cars installed on two wheels. Why not put all four wheels on? What should I pay attention to when installing and using snow chains? Suggestion: First confirm whether your car is front-wheel drive or rear-wheel drive, because the chain must be installed on the main set of tires. In automatic transmission, attention should be paid to installing snow chains on both front wheels (rear wheels) at the same time. Don't use snow chains on only one wheel, because it is easy to damage the automatic transmission.

6. What are our common misunderstandings about cars?

1. The greater the displacement, the more fuel consumption.

I think this is the most serious misunderstanding of the Chinese people, and it is rarely corrected. In fact, large-displacement high-speed cruising is generally more fuel-efficient because of low speed, and it is not necessary to step on the accelerator to accelerate overtaking. Small displacement has advantages only at idle speed and low speed. Generally speaking, the same engine technology, moderate displacement is the most fuel-efficient.

2. A car is more fuel efficient than a big car.

Small cars are usually lighter than large cars. At low speed, because the main resistance is the rolling resistance which is greatly influenced by the vehicle weight, it does have an advantage in fuel consumption.

3. Manual gear is more fuel efficient than automatic gear.

This sentence was correct in the early stage of the development of automatic transmission. Compared with 4AT, the traditional 5MT has more gears, lower cruising speed and no loss caused by torque converter, so it is generally more fuel efficient.

4. Turbocharging is more fuel efficient than naturally aspirated engine.

This sentence is not all wrong. For high-end cars, if you want to pursue extra power, it is generally more fuel-efficient than adding turbines, increasing displacement and number of cylinders without changing displacement.

7. What are the common sense mistakes that novices are prone to make on the road?

Novices and new cars should be on the road for some time, but many novices are eager to drive their new cars to the expedition.

Traveling on the road was originally a happy thing, but a new car novice undoubtedly increased the uncertainty in the journey. Here, in addition to reminding the novice drivers to be bold and cautious during the journey, it is also very necessary to be familiar with the performance, use and usage of the car. It is easy to make jokes if you are not familiar with the vehicle manual, which may even damage the vehicle and even lead to traffic accidents.

The following 10 precautions belong to the basic common sense that car owners should know. As a novice, you must find out. 1, the phenomenon that the back door can't be opened: the passenger in the back seat wants to get off, but finds that the door can't be opened. As a result, he opened the door with a flick of the handle outside the sliding door.

A novice may think, oh, no, the door lock seems to be broken! In fact, this is just a child safety lock. At that time, when buying a car, the dealer should have mentioned this function to you, but forgot it when actually using it. Analysis: the back door can't be opened from the inside, just because the child lock was accidentally activated.

In order to prevent children from accidentally opening the door from the car, many vehicles are equipped with child locks. After the child lock is activated, the back door can only be opened from the outside. If this is the case, just close the child lock.

The child lock position of some cars is near the door handle of the back door, and the lock position of some cars is arranged on the side of the back door, which can only be adjusted by opening the door. 2, air conditioning is not strong enough phenomenon: I really envy other people's car air conditioning is so good, sitting in other people's car often feels cold, while my car air conditioning is turned on to the maximum, at most it can only be "not too hot", and it takes a long time to cool down every time I turn on the air conditioning in the sun.

Analysis: Don't envy other people's air conditioners. Read the instructions first, and you will probably know why. You ignore the function of the inner and outer loop buttons. If the vehicle starts the air circulation inside and outside the air conditioner, the cooling effect will be obviously reduced, but the advantage is that the air is fresher.

On the contrary, if the air conditioning internal circulation is simply adopted, the refrigeration capacity will be greatly improved, but the disadvantage is the lack of internal and external air exchange, and the air in the compartment is not fresh enough. In addition, the quality of the solar film and the working condition of the engine will affect the air conditioning effect.

3. The phenomenon that there is no car to give way when changing lanes: It takes a lot of effort to change lanes every time. Nobody seems to want me to change lanes. The car is really tired! Many novices will have this idea and even feel wronged. Why can't drivers in this city be modest? Analysis: The more drivers drive in big cities, the more impolite they are, which is also a knowledge. But beginners should also take a good look at themselves.

First, did you turn on the light when you changed the line? If you don't, it will give people the impression of forcibly changing your lines, and naturally you won't let you from the bottom of your heart; Second, do you change lines across the solid line? Many novices don't have the concept of changing lanes in advance, and often realize that they have to change lanes before they reach the stop line. But at this time, they have changed lanes in solid lines, and others certainly don't want you to come again. And if there is any collision at this time, you will bear the responsibility of the accident, because you changed lanes illegally. If you consciously pay attention to these two aspects, you can accurately judge the distance between the vehicle in the next lane and yourself through the rearview mirror and judge the time to change lanes. In fact, it is not so difficult to change lanes.

4, often swayed by headlights: often swayed by others with headlights, this is the treatment that novices often receive on the road. Similarly, while having to admit that the current driving atmosphere is not good, novices should also check whether they have offended others in some ways. Analysis: There are two main possibilities for novices to be swayed by headlights of other vehicles.

First, they turn on the high beam first, and novices are often unconscious. They just think they can see the high beam more clearly, and some novices don't even know where the adjustment buttons of the low beam and the near beam are. In fact, just like the feeling of being swayed by other people's headlights, others will naturally feel uncomfortable if they are dazzled by your high beam. It's revenge to shine a high beam on you, and sometimes you should learn to put yourself in your shoes.

Another possibility is that novices like to occupy the overtaking lane for a long time after driving, especially on the expressway. They feel that there are few cars in the overtaking lane and there is no one to block them, but they don't know that their low speed has become a roadblock in the eyes of others. If the squeezing of the vehicle behind is ignored, it is reasonable for the vehicle behind to shake the headlights or even whistle. 5. An automatic car won't catch fire. Phenomenon: Novices, especially those who are not familiar with the manual, often tend to regard some normal situations as faults.

One of them is that turning the key won't catch fire. If you are a little more careful, or familiar with it for a period of time, you should understand where the problem lies. Analysis: Many drivers sometimes mistakenly put the gears in "D" and "R" to start the vehicle when they just started the automatic transmission, but immediately found that they could not start it.

In fact, this is the safety setting of the vehicle. Before starting the automatic transmission, you must put the gear in the "P" or "N" position and press the brake. In addition, it is impossible to pull out the car keys without putting the car back in the "P" position.

This situation is unlikely to happen when the owner gets up to drive in the morning, and most of them happen when the driver stops to wait for someone or rest. At this time, if the above situation cannot be started, it depends on the gear. 6, the steering wheel stuck phenomenon: when starting the vehicle, I was surprised to find that the car key could not turn, or the steering wheel was stuck. Don't worry about thinking that the car is broken, let alone making a fuss, find someone to repair it, because this is just a small function of the car-the steering wheel lock has played a role.

Analysis: the steering wheel is locked, and almost all cars have this function: after each use, pull out the key and turn the steering wheel gently, only to hear a bang, the steering wheel is locked. Although the steering wheel lock looks primitive compared with most electronic anti-theft devices, for thieves, even if the car starts successfully, the steering wheel can't turn, so it still has a good anti-theft effect.

But sometimes when parking, the steering wheel is placed at a certain angle, which is just enough to twist the key to ignite but can't unlock it. This will happen. At this time, the car mainly uses the right hand to gently twist the key, and the left hand turns the steering wheel, and the steering wheel naturally unlocks.

7. New cars are always dead. Phenomenon: start the vehicle in the morning, but.

8. What should I pay attention to when using a car?

When summer comes, the vitality of the virus will decrease under high temperature. Actually, this is a wrong view.

There are also many virus epidemics in summer, and there are also many respiratory and intestinal epidemics. Secondly, we should pay special attention to the prevention and treatment of digestive tract diseases.

More and more evidence shows that SARS can also spread through the digestive tract. In Hong Kong, 65% of SARS patients suffer from diarrhea.

Summer is coming, so we should pay special attention to food hygiene. Third, clean up the garbage in time and kill the fly larvae.

Mosquitoes don't spread SARS virus. However, flies may spread viruses through the digestive tract.

Professor Pan reminded residents that garbage should be removed in time, feces should be treated harmlessly, and aquaculture products that cannot be removed in time should be killed with organophosphorus pesticides. Fourth, pay attention to ventilation.

Because ventilation can dilute the virus to the lowest concentration. After entering the summer, the frequency of turning on the air conditioner is getting higher and higher. When turning on the air conditioner, attention should be paid to cleaning the filter screen in time and intermittent ventilation.

In some units and large-scale activity places, it is best to turn off the central air conditioning. Fifth, wash your hands frequently.

Because the chance of hand pollution increases in summer, the possibility of transmission through the digestive tract is greatly increased. At the same time, the bathroom should also be disinfected, but it is not appropriate to over-disinfect ordinary rooms.
