The beginning of winter has passed a few days ago. It has started to snow in many parts of the north, and winter has suddenly entered in some parts of the south overnight. When winter comes, many car owners will have a question in their minds, asking why driving in winter seems to consume more fuel than in summer. Is it because there is something wrong with their driving style? So what is the real reason? Let's talk to you about the fuel consumption of driving in winter.

Warming up the car for a long time will increase fuel consumption

We know that most car owners have the habit of warming up the car first when driving. This habit does not matter in any season, and then in winter, the time to warm up the car will become longer. First of all, we have to say that it is a good habit to warm up the car before driving, but it is not necessary to warm up the car for a long time. When the car is cold-started, the fan is stopped and the thermostat valve is also closed. At this time, the engine coolant only circulates in the engine water jacket and is not easy to dissipate heat. At the same time, the computer is affected by the temperature index of the sensor and will issue instructions to increase fuel injection and increase the opening of the idle valve. This increases the engine speed, which is conducive to rapid heating of the engine. Therefore, if the car owner heats up the car for too long, it is the primary factor that increases fuel consumption.

Now that we know that warming up the car for a long time will increase fuel consumption, how should car owners warm up their cars correctly? First, after the car owners warm up the car in place for half a minute to 1 minute, and then wait until the speed stabilizes, they can drive on the road. Remember to control the speed of the car, not exceeding 50km/h, shift gears gently and keep the oil on. This is the most standard and correct way to warm up the car. Energy saving, environmental protection and low carbon accumulation.

Turning on the heater in winter also costs fuel.

We know that heating the car for a long time will consume fuel. In winter, car owners will definitely turn on the heater when they get in the car. We know that a car engine needs to be maintained at a normal temperature when working, which is about 80℃-90℃. In winter, the engine needs to retain heat rather than dissipate it. Due to the influence of flowing air, the temperature of the car engine is not easy to maintain around 80°C, especially when the weather is extremely cold. In addition, when the warm air is turned on, in order to maintain the body temperature, the engine will increase the amount of fuel injection, thus increasing fuel consumption.

The editor concludes: Warming up the car for a long time in winter will increase fuel consumption, and turning on the heater will also consume fuel. In addition, the decrease in battery efficiency will also cause the car owner to consume more fuel. But there are more than just these factors that lead to high car fuel consumption. For example, when the temperature is low in winter, even if the car owner uses a matching engine oil model, the viscosity of the oil will still thicken in the early stages of starting the car, and the engine will consume more oil. Therefore, the increase in fuel consumption is not just caused by any one component, but must be combined to increase the total fuel consumption of the car.
