When a car wades in the water, how deep is the water to allow the car to pass smoothly?

When the water depth is one-third of the height of the tire, you can pass with confidence, but when the water depth exceeds half the height of the tire, you should be careful, because in this case, it is easy to cause water in the car. If you wade deeper than the bumper, you should be vigilant when driving to avoid water ingress into the engine. If the engine of the car gets water, never start the car again, otherwise it will cause great damage to the car.

Car wading practice.

1. It is best to turn off the air conditioner (to prevent the electronic fan from opening) After the vehicle turns on the air conditioner, the electronic fan located at the front of the car will rotate often, and the rotating fan blades will stir up some water splashes when wading, which may cause the engine to enter the water, so try to turn off the air conditioner when wading, and then enter the wading section after the electronic fan is closed.

2. When wading in the water, there is an opposing car to accelerate appropriately (to offset the waves of the opposite vehicle) If there is a car on the opposite side when wading, you must pay attention to the height of the water wave in front of his head, if the water wave is too high, you need to accelerate appropriately at this time, the reason is that you can use the water wave generated by your own side to alleviate the water wave caused by the opposite vehicle, you must pay attention to not panic when encountering this situation, let alone step on the brakes!

3. It is best to turn off all electrical equipment when wading (to prevent overload and short circuit) Before wading, all on-board electrical devices should be turned off, such as: air conditioner, radio, tachograph, cigarette lighter, etc., in order to prevent electrical equipment from entering the water and causing power failure and short circuit.

Continuous rainstorms come one after another, and at this time, motor vehicles on the road will inevitably face the situation of flowing over the waterlogged road.

The wading depth of a car is the height of the engine's air intakes. Most low-chassis compact cars and small cars pass through waterlogged roads based on the location of the vehicle's air intakes. The function of the air intake is to suck in air, and if the water depth exceeds the height of the air intake, then a large amount of water will be sucked into the car by the engine, and the car will be seriously damaged.

Therefore, when passing through waterlogged roads, pay attention to the depth of water and the speed of the vehicle.

The chassis of the vehicle is the "ground clearance" item in the parameter configuration table when purchasing the car. The greater the ground clearance and the higher the chassis, the higher the safety factor when navigating waterlogged roads. Most low-chassis compact and small cars should be marked by the location of the vehicle's air intake when passing over waterlogged roads.

The safe wading depth is the distance the vehicle has ground clearance, and if the wheels are more than two-thirds deep after entering the water, the safe range is exceeded, and the vehicle may be flooded.

Precautions for car wading.

If you do need to wade into the water, first determine how deep the wading is at the deepest point, which cannot exceed the midpoint of your wheel, which is the pumping point of the car. If there are vehicles passing through, the water surface height can be observed according to the passing vehicles; If there are no other vehicles, you can find a stick to test the depth of the water ahead. Do not wade through after knowing the depth of the water.

Do not wade in the water after another vehicle, and wait until the vehicle in front of you has completely passed or confirmed that it does not affect your passage before starting to wade, otherwise you will have to stop in the water once the vehicle in front breaks down, which will increase the danger. It is not possible to wade multiple vehicles at the same time, so that waves will form on the water surface and affect each other's direction.

Some vehicles are designed with a compartment drain on the chassis, and if the water does not pass the chassis, it may be poured into the compartment from the drain hole.

The circuit, engine, and transmission are all sealed, and there will be no water ingress, rest assured, if you can increase the air intake, it is no problem to be a submarine, but be careful, the car is not completely sealed, and wading too deep for a long time will also let the water pour into the cabin.

It doesn't matter. Sometimes when washing the car, I spray the inside of the engine with a water gun. As long as the intake and exhaust pipes do not enter the water, it is fine. Also, if the water really goes out of the fire, don't try to start the fire, as soon as the fire is fired, it will be over.

First of all, as long as the water depth does not exceed the air intake, the car will not turn off. There is no problem.

If there is no flameout when passing through the water, then there is no effect on the engine, only automatic flame-off and breakdown. After deep water, it will generally cause short circuit of wires, poor contact, water ingress into the engine, rust on the car body, fabric, sound insulation layer, etc., mold, etc. So after wading through the water, open the front machine cover, 4 doors and trunk, dry it to avoid moisture erosion, and check it carefully.

Of course, wading in the water also has to pass through at one time, even if the car is soaked in water. After a long time, the water came in.

Even professional top-of-the-line off-road vehicles should try to avoid wading, and racers will not wade unless they have to.

Wading in the water is too risky. In case the water exceeds the limit, the car floats up, loses grip, and can't get out of trouble, just wait for overhauls.

The next time you have to wade into the water, look at the approximate height of the water, and the engine should not be flooded when the water depth is about half the height of the tire. After the water recedes, it can be driven to the maintenance shop for chassis or exhaust pipe cleaning. When the water depth exceeds half the height of the tires, the engine compartment and the passenger compartment may have been flooded, and the electrical system will be flooded and short-circuited.

At this time, do not start the engine rashly, and after the water recedes, please tow the tow truck to the repair shop for repair. If you start the car rashly, it can cause serious damage.

Post-wading measures:

Check the electrical system.

Immediately remove the wrapping from the electrical part, wipe off the wet part, and install the fan belt. Check whether the gearbox is soaked in water, whether there is drift blockage between the radiator plates of the water tank, whether the tires are damaged, and whether there are aquatic weeds under the chassis.

Clean the vehicle in time to restore the braking effect. Do not attempt to start until you have determined that the electrical system, engine components, etc., have not been flooded, so as not to cause further damage.

How can I safely drive through wading roads? Figure it out and stop spending money on lessons.

As long as the car wading is less than the height of the half wheel, it will basically be fine, and if the wading reaches the height of the half wheel, or even exceeds, it will need to be inspected in detail. If the wading height reaches half a wheel, or even exceeds, it may cause the engine to stall due to water ingress, and there is also a possibility of water seepage in the car, which will affect the engine and the electronic equipment, components and wiring on the car.

As long as the car wading is less than the height of half the wheel, it will basically be fine, if the wading reaches the height of the half wheel, or even exceeded, it needs to be checked in detail.

As long as the car wades in water less than half a wheel, it will at most flood the exhaust pipe, which will not cause water to enter the engine intake system, and the exhaust pipe will be flooded, and there will be no water sucked back into the engine.

If the wading height reaches half a wheel, or even exceeds, it may cause the engine to enter the water and stall, and the car may also cause water seepage, and the engine and the electronic equipment, components and wiring on the car will be affected by the random lighting.

How do you know if something is wrong after the car wades in the water?

1. Air filter: Open the engine compartment, find the air filter, disassemble it with a tool, check whether the air filter is wet, if the air filter is not wet, it means that there is no problem; If the air filter and air intake duct are wet, do not start the car again, and tow the car to the 4S shop for maintenance in time;

2. Chassis: check the sealing of the chassis, whether there is water ingress into the universal joint, steering cage dust jacket and other parts, and whether there are foreign objects stuck in the chassis;

3. Car lamp: If the car wades deeply, the sealing of the car lamp cover is not good, which will lead to water seepage, so that the water mist will form inside the lamp, which will affect the light transmission; If the lights don't form a water mist, there is generally no problem;

4. Oil: check whether the engine oil, brake oil, transmission oil, front and rear axle oil have increased, or there is an abnormality;

5. Inside the car: detect whether there is water seepage in the car, whether the interior of the carpet, floor mat, soundproof cotton and other interiors is wet, and if so, check whether the wiring of the electronic equipment in the car is wet.

Car wading depth:

1. The maximum wading depth refers to the maximum depth that can be wading through under safe driving conditions. The greater the maximum wading depth, the stronger the wading ability.

2. The height of the air intake is the wading depth, which determines the wading depth of the car, first of all, the height of the engine intake.

3. If the air inlet is lower than the water level when wading, the water will be sucked into the cylinder of the engine, because the water is not compressed like air, it will be known to cause serious damage to the mechanical structure of the engine (connecting rod, piston, crankshaft, etc.). Therefore, the wading depth must not exceed the height of the engine air intake.

1.Find out what's going on under the water.

That's the most important point! Wading is still very different from the kind of wading in the city with heavy rain, because the chance of encountering special underwater conditions in the city is very small, one of which is that the manhole cover of the underwater road surface is washed away; In the section of the non-urban road, there will be more underwater conditions, so the most traditional and practical way is to use a long stick to find out the depth of the water, generally speaking, you can pick up a long branch.

2. Estimate the impact on the vehicle.

In addition to understanding the underwater situation clearly, it is also necessary to make a rough estimate of the difficulties of driving the vehicle, one is to observe whether the water will soak into the floor or exhaust pipe in the cabin, and the other is to observe whether the water exceeds the center line of the tire, if it exceeds the above two standards, it is easy to have a serious impact on the vehicle engine and computer and other components.

3. The compensation of wading insurance is conditional.

In addition, it should be reminded that it is not your car that has purchased full insurance or wading insurance, and you will definitely be able to get compensation after the vehicle wades into the water, if the vehicle is damaged due to improper operation caused by water, the insurance company will not pay compensation.

Summary: Wading is a special driving skill, there is no harm in learning more, you can increase the efficiency of escape when the road is unpredictable, but this skill is still not used as much as possible, for drivers who have not mastered the special off-road driving skills, there is no need to try and show off this skill, because the danger of wading is far greater than the entertainment, not worth it.

There are many characteristics of wading in the water and driving in general: the buoyancy of the water will reduce the traction capacity of the car; It is easy to crash when the underwater ground is soft; When the water is deep, it is easy to enter the exhaust pipe and turn off the engine; Flowing water will have an impact on the car, causing difficulty in moving forward or moving sideways, etc., so the following issues should be paid attention to when wading in the water

1.Before wading into the water, it is necessary to check the safety inspection of clean water, flow rate, flow direction, etc. Check that the car is in good condition and in good condition.

If the tyre and brake drum are overheated, allow them to cool down properly before wading. When the water depth exceeds the maximum wading depth of the car and it is necessary to wade, the shutters should be closed, the fan belt should be removed, and the distributor, high-voltage line and ignition coil, fuel tank, oil dipstick hole, etc. should be waterproof and protected. Raise the battery position and raise the exhaust outlet.

At this time, the engine should not be turned off, and manpower or other vehicles should be organized to assist in towing it out to prevent it from falling deeper and deeper. �

3.After wading, the car should be inspected, the waterproofing equipment should be removed, and the parts should be restored to their original state. Drive at low speed for a long distance, use the hand and foot brakes several times in a row, so that it rubs and evaporates the water on the brake drum, restores the braking efficiency, and then drives normally, and quickly goes to the professional car maintenance center for the whole car inspection to prevent some mechanical failures.

Practice has shown that drivers with different skill levels can drive the same vehicle on the same road with a difference of 20-25% in fuel consumption. The following is a list of some data on the impact of incorrect driving operations on fuel consumption for the driver's reference.
