Why will the engine be destroyed if the car is not heated correctly in winter? What is the most reasonable hot car?

With the arrival of winter, hot cars have once again become a topic of concern for owners. Although modern automotive technology has evolved from carburetor to electric injection, the need for hot cars still exists, but for a shorter period of time. The purpose of the hot car is to allow the oil and coolant inside the engine to reach the appropriate working temperature to ensure that the parts are fully lubricated and reduce wear.

In the cold winter, the gap between parts is large when the engine starts, which is easy to lead to wear. The hot car helps the parts heat up and achieve the best fit clearance. For example, in an environment of minus 10 degrees, the engine sound of the vehicle that has just started may be larger, but as the temperature rises, the sound will gradually return to normal.

So, how to heat the car reasonably? First of all, the original geothermal vehicle is necessary, but the specific time should be adjusted according to the temperature. When the temperature is higher than 0 degrees Celsius, the original geothermal vehicle is basically not needed, and can be directly driven. When the temperature is about minus 5 degrees, it is recommended that the original geothermal vehicle 30 seconds to 1 minute, and then drive at a low speed for about five minutes. When the temperature is minus 10 degrees and below, the original geothermal vehicle is 2 minutes, and then it is slow for about five minutes. If the temperature is lower, the heating time should be extended accordingly.

It should be noted that it is not recommended that the original geothermal vehicle take too long, because it will lead to fuel waste and accelerate carbon accumulation. One owner caused the throttle to be too dirty because the car was hot for a long time, and the fault light turned on when the new car was only driven 10,000 kilometers. Therefore, the winter hot car should be moderate, according to the local temperature to determine the hot car length, the general original heat 1-3 minutes is enough for most people.

Hot car is an important part of vehicle maintenance in winter. The correct hot car method can not only protect the engine, but also improve the driving safety of the vehicle. Owners should take appropriate hot car measures according to the actual temperature and vehicle condition to ensure that the vehicle can maintain good performance in cold weather.
