A hot car is needed. The weather in winter is relatively harsh, and the temperature in the north will be much lower than that in the south, so if the cold car is directly driven, long-term operation will cause problems such as engine shaking or abnormal noise. The south will be better, but in the cold weather environment, it is also necessary to drive normally after the hot car, which can better protect the engine. Of course, the hot car is also moderate and does not need to be hot for a long time, otherwise the idle time is too long will also have a bad impact on the vehicle, such as causing more carbon deposits, and waste of fuel, which is also not worth the loss.
The specific time of the hot car is related to the temperature and geographical environment, and we can follow a more objective judgment standard. We drive in the winter after the vehicle is put away for a long time, after starting the vehicle, we will see that the water temperature will slowly rise, and when the water temperature reaches the normal temperature, it means that the process of the hot car is completed, and then you can drive normally. If there is something you really can't wait for, it is recommended to drive slowly after starting, and also wait for the normal water temperature to drive at a normal speed.
The longer the winter hot car, the better?
Obviously not. In the winter, the car will be in a low temperature due to the low temperature of the weather, resulting in the oil in the engine in a low state. This state returns to normal temperature soon after the model is started, so we only need to wait for the water temperature to rise to the normal driving water temperature, and we don't have to heat the car for a long time. Long-term heating of the car will cause the fuel consumption of the vehicle to increase, waste of fuel will also make the carbon deposit increase, it seems that it is not helpful to the engine but harmful.
In winter, there is no time for the hot car to drive away directly
In the case of no time to heat up the car, it is recommended to just start the car and let the car drive slowly. When the water temperature reaches a normal scale, accelerate again. Do not directly accelerate with one foot on the throttle, otherwise it will also have a certain impact on the engine. Some drivers feel that there seems to be no impact, in fact, the engine problems are slowly emerging, will not be reflected at once, so it is very important to develop good driving habits.
In winter, the northern hot car lasts longer than the south
yes. Because in winter, the temperature in the north will be much lower than in the south. A very obvious example is that snow is often seen in the north and rarely seen in the south, so the car driven in the south can be slightly shorter when the car is hot, and the vehicle driven in the north is longer. From the experience point of view, the colder the temperature, the longer the hot car, and the specific length of time can be based on the normal water temperature after the vehicle is driven.
Tips
Today's car engines use direct injection or electronic injection, so the hot car does not take too long. We only need to pay attention to this big principle, the water temperature is not normal before the best in the hot car state, so that the car can also play a better protective role.
