During this period, successive cold currents swept the country again and again, adding a lot of realism to the arrival of winter. At the same time as the temperature drops, many owners have new troubles. Usually the moving distance is very close, the car can not be driven all day, and the water temperature often does not reach the middle value. Therefore, many owners are worried about whether this operation will cause damage to the car after a long time. Generally speaking, in the winter, the operation of heating the car before driving, on the one hand, reactivates the engine, on the other hand, the internal temperature of the car rises, which can improve the driving experience of the car. However, some car owners are impatient, and even chased by time, stepping on the accelerator without waiting for the heat to rise. As a result, the damage to the car is higher than that of a car that needs to travel a long distance.
This is because, in the case of relatively low temperatures, after the car is parked for a long time, the oil in the engine will flow into the oil pan in the lower part of the engine. When the owner starts the car, most of the engine is not protected by oil. Using an oil pump to make the oil flow again, lubricating the pistons and connecting rods of the engine, etc. takes a while to run. Therefore, cold start will cause a certain degree of damage to the engine, reducing the life of the engine. Therefore, for car owners who need to drive short distances and do not like to drive a hot car in advance, their car is likely to be inferior to the taxi that travels on the road every day.
This wear and tear will affect our subsequent cars, and will not drastically reduce our body experience? For most private cars, the annual mileage is about 10,000 kilometers, and many places may reach 20,000 kilometers. In the current automobile manufacturing industry and technology, in addition to the reliable wear resistance of various parts inside the car, most owners will choose a fully synthetic oil with better effect and higher durability when repairing the car. Therefore, this level of wear and tear is not as severe for the car engine as we think, and with a driving distance of less than 300,000 kilometers, it has little impact on the driving experience.
That is to say, in the case that the owner does not need a high-intensity, long-distance car, the cold car start will not actually lead to unacceptable results for the owners. If a car is maintained in a timely enough manner, the impact of this wear and tear on the owner is minimal. Before the owner can really feel the impact of this wear and tear, this car will basically take more than ten years, so it should generally be replaced. So, in fact, you don't have to care about heating the car before driving in winter, and driving a cold car doesn't have a big impact on yourself. However, hot cars can increase the temperature inside the car and improve the driving experience, so most cars are basically removed from the hot car.
Summary: For everyone, driving in winter, not only to heat the car in advance, check the antifreeze of the car, replace the anti-slip tires of the car, but also pay attention not to drive under low pressure for a long time.
