Is it normal for cars to be particularly expensive in winter?

Cars in Pacific Auto Network generally consume more fuel in winter and the temperature is low in winter. For example, a good working condition of an engine requires a certain temperature, generally around 90 degrees. Only when the engine is in good working condition will the fuel consumption be normal.

1, the engine needs a certain temperature to reach a good working condition.

Usually at 90? Only in this way can the engine maintain a good working condition, and the temperature itself is high in summer, which is easy to achieve and maintain. Because of the low temperature in winter, do you want to reach 90? It takes a long time, not to mention maintaining this state, so it takes longer to reach the best working state, and naturally it consumes more fuel.

2. Poor oil fluidity is another reason for increasing oil consumption.

In fact, this is still related to the temperature. As we all know, engine oil is liquid. In low temperature environment, the density will increase and the fluidity will become worse, especially for some high viscosity engine oils. Once the fluidity becomes worse, it will hinder the operation of the engine. If the engine wants to reach a normal working state, it must reach a certain temperature and increase the fluidity of the oil, so that the running time will increase and the fuel consumption will naturally increase.

3. Driving at low speed for a long time is also the reason for increasing fuel consumption.

Generally, it is the most fuel-efficient to drive at a speed of 70-90 mph, but because the temperature in winter is too low and the engine temperature is low, the operation of all components is not very good. Harmony? Although many friends start with low speed instead of hot car, it will take too long to keep the engine in good working condition. Driving at low speed for a long time will increase fuel consumption. Coupled with the rainy and snowy weather in winter, there are many foggy days. For safety, we should drive at a low speed. The increase in fuel consumption is also inevitable.

4, the habit of hot car

During cold start, the fan stops running, the thermostat valve is closed, and the engine coolant only circulates in the engine water jacket, which is not easy to dissipate heat. At the same time, affected by the temperature index of the sensor, the computer will issue instructions to increase the fuel injection and the opening of the idle valve, thus increasing the engine speed and helping the engine to warm up quickly. Therefore, long-term hot start is the primary factor to increase fuel consumption.

5, battery performance decline

In winter, the days are short and the nights are long, so it takes longer to turn on the headlights than in summer. In addition, due to the low temperature in winter, the chemical reaction of electrolyte is slow, which easily leads to battery loss. In order to overcome the resistance during the cold start in winter, the demand for electricity is also greater. Starting the engine needs more fuel to convert electric energy to charge the battery, so it is also a factor to increase fuel consumption. (Photo/Text/Photo: Pacific Auto Network Cao Bo)
