The heating fee does not contain oil.

There is no oil. The principles of warm air and cold air are actually very different. Warm air is formed by engine heat dissipation. There is a small fan in the engine compartment to blow the heat collected by the cooling system into the car. If the warm air is not turned on, this heat will also be discharged to the outside of the car. Therefore, the driving warm air is really just waste utilization and will not increase any fuel consumption.

Entering the car, because the temperature of the water tank in the car is still relatively low, turning on the warm air is not only not conducive to the increase of the temperature inside the car, but also increases the burden on the engine, resulting in the slow temperature rise of the engine. When the water temperature indicator reaches the middle position, warm air can be used. It is suggested that the cold air in the car should be exhausted by external circulation first, and then it should be switched to internal circulation after 3-5 minutes.

If the driver turns on the warm air for a long time, a slight gap can be exposed in the window, which can keep warm and prevent carbon monoxide poisoning.

The extended data automobile heating system can realize the functions of heating, defrosting and adjusting temperature and humidity.

In cold winter (even in late autumn and early spring), the automobile heating system can provide heating for the automobile and increase the temperature inside the automobile. In winter, spring and autumn, when the air humidity is high and the temperature difference between the inside and outside of the car is large, frost and fog will form on the window glass, which will affect the driver's sight and is not conducive to driving safety. At this time, turning on the heating system can remove the frost and fog on the window glass.

Automobile heating system is a complete set of devices that blow cold air to the surface of heat exchanger, absorb its heat and introduce it into the car, thus increasing the temperature inside the car.
