You can’t drive without the heater in winter. I’ve seen many saying that “opening the heater will increase fuel consumption” and so on. For car owners, fuel consumption must be the primary concern. So, does it cost a lot of fuel to drive the heater? ?
In fact, the warm air of the car is heated by the waste heat of the engine, that is to say, it is heated by the heat of the engine cooling water. The heating is also emitted into the atmosphere, so the warm air does not come directly from burning gasoline, which does not increase fuel consumption relatively.
Of course, the more serious parents will definitely say that the air conditioner fan does not consume oil? This kind of impact exists, but it will not be much. Compared with the fuel consumption of air conditioning and refrigeration in summer, it is negligible.
However, if the weather is extremely cold, the heat of the engine coolant can never meet the needs of the warm air, that is, even if the warm air is turned on to the highest level, it is still not warm enough. At this time, the engine water temperature may be low, which is not conducive to the formation and combustion of the mixture in the cylinder, which may indirectly lead to an increase in the fuel consumption of the car.
The high fuel consumption in winter is because the engine needs to be kept warm, the car needs to be warmed up, the oil thickens, road conditions, etc. Turning on the heater will not greatly increase the fuel consumption.
