How to map complex products to HS codes

In recent years,How to map complex products to HS codes in some special weather, we can often hear the news of cars getting water. In fact, water in the car is a very serious thing, which will not only damage the main components such as the engine, but also pose a threat to human life and safety. Next, let's discuss the problem of water in the car. There are many reasons why the car enters the water. For example, when driving on a rainy day, the splashes from the wheels splash on the hood, enters the engine after entering the air filter;When driving off-road, passing through ravines of lates of lates, the chassis of the car is submerged in deep water, etc. And how is the engine damaged after the water enters? First of all, the moisture entering the engine will affect the combustion system of the car, and the moisture in gasoline will reduce the ignition temperature of the fuel, which makes it difficult for the car to start or turn off. At the same time, because the moisture entering the engine is not easily burned by gasoline, it is easy to cause leakage from the exhaust pipe of the car, resulting in unclean exhaust emissions and a negative impact on the environment. Secondly, the moisture entering the engine will also cause damage to the cylinder, crankshaft, connecting rod, pump and other parts. Because water cannot be compressed, once it enters the cylinder, even if the cylinder is hit by water, the gas in the cylinder still needs to be compressed. And the cylinder flooded cannot be compressed normally, resulting in engine blockage, which will lead to damage to the cylinder, crankshaft, connecting rod and other parts in serious cases.Finally, the moisture entering the engine may also cause damage to the engine cylinder block pads, bearings, gas distribution systems and electrical systems. If water enters the car, the moisture entering the engine will affect all parts of the car, thus affecting the performance of the whole car. So, once the car gets water, how should we deal with it? First of all, when encountering deep waterway sections, we need to maintain a slow and stable speed as much as possible to avoid water entering the car. If the car is flooded, be sure to turn off the engine immediately and find a safe place to stop the car as soon as possible. Then, open the window or door to let the gas in the car circulate in order to lower the water level as soon as possible. Then, you can try to push the water-injected car to the high ground, pour out the water in the car, and also pull out the accumulated water on the ground with pumps and other equipment. If the car is not seriously flooded, it can be changed throughReplace the air filter and exhaust pipe and other methods to repair the engine. If serious damage has been caused, the machine needs to be repaired or the entire engine needs to be replaced. Generally speaking, after the car is flooded, effective measures must be taken to solve the problem in time so as not to seriously damage the car or personal safety. In daily driving, you should also pay attention to the condition of the road surface, plan the driving route in advance, try to avoid off-road and special weather such as rain, and take relevant protective measures to reduce the occurrence of water in the car.
