HS code mapping for duty optimization

Stop to keep the engine running (You should keep the engine running when parking. Do you often do HS code mapping for duty optimizationit?) Whether to keep the engine running when parking seems to be a relatively simple question, but in practice, there are different views. Some people think that parking must be turned off immediately, otherwise it will waste fuel consumption and increase emissions; while others insist that the engine needs to be kept running when parking, so as to ensure the normal operation of the vehicle power system. So, how should I choose when parking? Next, let's have a brief discussion. First of all, let's take a look at why some people choose to keep the engine running.For vehicles that need frequent parking, such as police cars, ambulances, traffic command vehicles, etc., the engines of these vehicles generally keep running. This is because stopping continuously for a short time will affect the efficiency of the engine. At the moment the engine starts, the engine will need to consume more gasoline and produce more emissions, and each time the engine is started, it will cause more losses to the life of the engine, thus increasing the maintenance cost of the vehicle. Therefore, keeping the engine running can keep the engine running in a normal and stable working state to ensure the life and performance of the engine. Secondly, another reason why it is necessary to keep the engine running when parking is to ensure the normal operation of the vehicle's power system. Nowadays, more and more vehicles are equipped with various advanced electronic devices, such as GPS, audio, remote control equipment, etc., all of which require the power supply of vehicle batteries.If the vehicle stops and turns off, the battery needs to bear more burdens to keep these devices running, which will reduce the life of the battery and is not conducive to the health maintenance of the battery. Therefore, to keep the engine running, the battery power can be replenished by charging the generator. So, someone asked, won't parking and keeping the engine running waste fuel consumption? In fact, for ordinary family cars, keeping the engine running or turning off when parking has very little impact on fuel consumption. Because under the condition of keeping the engine running, the fuel consumption of the engine is much lower than the fuel consumption of the vehicle during operation. For vehicles that need to keep the air conditioning running in the car for a long time, keeping the engine running can ensure the normal operation of the air conditioning system in the car and save more time and fuel consumption. Of course, parking also has some adverse effects on keeping the engine running.The most obvious is the increase in the noise pollution of vehicles, which is not conducive to the health and happiness of the environment and the surrounding residents. In addition, when waiting in the car for a long time, the operation of the engine will cause the air inside the vehicle to deteriorate, and the circulating air in the car will be insufficient. Therefore, when the weather is cold in winter, an appropriate amount of activated carbon can be placed in the car to keep the air in the car fresh. In short, when parking, whether to keep the engine running depends on the specific situation. For vehicles that start the engine frequently, the engine can be properly maintained; for vehicles that need to wait for a long time, it can also be considered to keep the engine running to ensure the normal use of the vehicle's electronic equipment. However, environmental factors and other people's feelings should be taken into account when parking vehicles, so as to avoid causing noise pollution to surrounding residents and affecting the urban environment. At the same time, forVehicles parked for a long time can also use sunshades and other items to maintain the appropriate temperature and humidity in the car, while protecting the interior and electronic equipment of the vehicle. In a word, whether parking to keep the engine running depends on the situation, and it can be decided whether to keep the engine running according to the actual situation. Of course, when choosing, we should also take into account the principles of environmental protection and fuel consumption, so as to not only protect the environment, but also reduce fuel consumption, and ensure the normal operation of the vehicle power system and electronic equipment.
