How to rescue your car after it is flooded in a sudden heavy rain to avoid greater losses[汽车维修知识]

In the past two years, the frequency of visits by strong convective weather has been increasing, and the rainfall in a short period of time has been very considerable, especially in some road sections, where there is a lot of stagnant water, and these places are often flooded by vehicles.
Hardest hit area.
Looking at the current weather conditions, vehicles may be flooded for some time in the future. Last week, "Big River Car City" introduced wading driving and rainproof equipment. This week, the reporter specially asked maintenance experts and insurance professionals. Ask for advice and see how the owner can avoid losses to the greatest extent in case the vehicle enters water.
70% of the vehicles flooded caused a fluke
When the water in front is too deep, many car owners will have the idea of ​​"whether or not to live" in their minds. However, fromcarThe reporter from the 4S shop's maintenance master learned that he knew the consequences of wading, but he had to pass through because of a fluke. As a result, more than half of the flooded vehicles were flooded because of a fluke.
Zhao Haibo, workshop director of Henan Xuzhi Automobile’s after-sales service department, told reporters: “Every time after heavy rains, car owners who come to repair cars generally know the danger of wading into deep water. The engine water intake accounts for 70% to 80%."
There may be many reasons to forcibly pass through the deep water section, but many car owners do not understand the structure of their car, so it is a bit risky to take a chance in this situation. Zhao Haibo said, whether the vehicle will be flooded, we must first understand the level of the air intake of your car. "Generally speaking, the height of the air inlet and the headlights are about the same. If the water surface is more than half a wheel, then you must not forcibly wade through the water; if the water surface is below half a wheel, you can pass carefully, but keep it steady. The speed of the car, if the sparked waves exceed the position of the intake duct, it is also difficult to escape the bad luck of being flooded. As for the current running cars on the market, because of the different vehicle structure design concepts, the American, Japanese and German cars are easy to be flooded. French and British cars are not easy to be flooded. This point can be used as a reference for car owners."
Deal with it urgently to avoid loss when it is flooded
Many reports have introduced that the engine should be turned off and not started when it is flooded, but what to do next is unclear. Either we will further introduce the rescue call, but after the call, what else will the car owner do? Master Zhao Haibo believes that the car mainly does a lot of things.
First of all, let's understand why it is not allowed to restart after flooding.Zhao Haibo told reporters that after the car is flooded, water will enter the engine from the intake port, causing the engine to stall. At this time, water will accumulate in the cylinder chamber.Spark plugIn the case of being exposed to water, if the owner starts the engine, it willpistonThe connecting rod bends, causing damage to the engine. After watching this process, maybe you will remove your hand from the ignition key when the vehicle is flooded.
Not restarting is a prerequisite. At this time, the way the owner handles the emergency has shown great power! Don't open the car door and call for rescue as soon as possible. In fact, if the situation is urgent, you can lower the glass and come out of the car window. If the situation is not very urgent, don’t panic in the car after calling for rescue, because the airtight effect of the vehicle is pretty good now, the drainage channel on the chassis is designed with one-way valve, and no water will enter in a short time. It is a good idea to wait for the rescue vehicle to come.
In addition, Zhao Haibo suggested that car owners put a set of tools in the car before the heavy rain.wrenchIt came in handy. Because after the car key is unplugged, the whole car still has a small amount of electricity to supply the engine computer, anti-theft system and other electricity. After the car owner comes out of the car, he must find a way to first loosen the screw that fastens the battery cable with a wrench. Remove the battery negative wire, so that you can avoid short circuits caused by water in the electrical appliances on the car, causing greater trouble.
