Don't turn on the warm air immediately after the cold car starts.
In order to keep warm in winter, it is foolish to turn on the warm air as soon as you get on the bus! When the car is just parked, the cooling water temperature of the engine is not enough to meet the heat required by the warm air, so don't rush to use the warm air after the car is parked, which will not only consume oil, but also achieve the effect of heating. For vehicles with automatic temperature control and air conditioning partition, preheat the engine until the water temperature reaches 50 degrees Celsius, set the temperature inside the vehicle and start it. It should be noted that if the warm air is not used for a long time, it should be checked in advance before use, and the switches and pipes should be checked for signs of water leakage.
You don't need to turn on the A/C key when you turn on the warm air.
To use air conditioner in summer, you must press the A/C key first (the air conditioner switch controls the compressor and the air conditioner in the car, which has nothing to do with the warm air). Warm air uses the thermal cycle in the car, so it doesn't need to start the compressor, so it won't cost oil, so you must remember that you can turn on the warm air only by adjusting the air conditioning button, and don't touch the A/C switch.
Warm air temperature should be controlled at 18℃-25℃
The most comfortable temperature for human body is 20℃ to 25℃, and the indoor temperature should be controlled at 18℃-25℃. If there is not enough hot air to reach the set temperature, the engine will do extra work to generate more heat energy, which will consume extra fuel.
Internal circulation mode is more fuel efficient.
In the daily use of air conditioning, the internal circulation mode is more fuel-efficient because it avoids the loss of cold air in the cab. When the indoor temperature drops to a certain temperature, the air conditioner compressor will stop working. But the disadvantage is that the air is not very good and the noise will be louder.
Let the air conditioner "take a break" appropriately.
Using air conditioner for a long time will make the condenser pressure too high, which will not only cause losses to the refrigeration system, but also reduce the refrigeration effect of air conditioner. So we should seize the opportunity to let the air conditioner "take a break". For example, when there is traffic jam on urban roads, turn off the air conditioner three to five minutes before arriving at the destination, which can not only reduce fuel consumption, but also avoid the odor generated by the air conditioner.
What should I do if the warm air is insufficient?
There are two reasons why the vehicle heating system is not hot: it is caused by the engine cooling system; The control device of warm air is not working properly. Drivers must first determine what causes it. The method is simple. Look at the temperature of the two inlet pipes of the small warm air tank. If both pipes are hot enough, there is something wrong with the air volume control mechanism. On the contrary, if both pipes are cold, or one is hot and the other is cold, it is a problem with the cooling system. It is best to go to a repair shop or a 4S shop for maintenance.
In short, nine times out of ten, it is because of the above reasons that it costs oil to turn on the warm air. In addition, the reason for the increase in vehicle fuel consumption is driving habits, such as frequent braking, road conditions and car conditions. In fact, developing good driving habits, maintaining good car condition and maintaining and replacing parts will reduce fuel consumption! In the future, riders don't have to worry about whether the warm air will consume oil. It's getting colder and colder, and it's cold in the car, so I can't put my hands in my pockets!
Finally, remind riders to turn off the warm air when parking for a long time, because the car stops, the warm air continues to be on and the window is closed, so the concentration of carbon monoxide emitted by the engine will increase due to gradual accumulation, and the window can reveal a slight gap, which can keep warm and avoid carbon monoxide poisoning.
