Calculate the summer air conditioning fuel consumption increased by less than 60 per cent do not open

Summer has come, for a friend who often drives a thing that must be experienced--into a car exposed to the sun for a noon. This acid is so good, of course, before you get on the bus, it's better to open all the doors to the air than to turn on the AC directly, not the topic we're going to talk about today. We are here to talk about a lot of car owners are concerned, but not necessarily clear of the problem, that is open air-conditioning drive fuel consumption increased how much?

Before the article reported that many car owners because of economic reasons, rarely used in the summer car air conditioning. "My car usually fuel consumption of about 10 kilometers (liters) of oil, if used air-conditioning, feel the speed will come down, fuel consumption also miso to rise, love dearly died, one months to spend more than two hundred or three hundred, too expensive! "Is it true?" After reading this article if you carpool to meet this driver, PA pa How much money to shoot him, let him give ye/gu grandma to open the air conditioning.

About 20% of engine power in air-conditioning

It is understood that the car use of air-conditioning when the corresponding increase in fuel consumption, but can increase to what extent, most drivers are still more vague. According to the professional explanation, the car air conditioning about 20% of the engine power, so open air conditioning will use off part of the engine power, fuel consumption will increase, the specific fuel consumption increases with the car displacement and speed. Usually hundred kilometers fuel consumption 10 liters of cars, air conditioning when the fuel consumption will increase by about 2 liters. The effect of air conditioning on fuel consumption is very obvious, the effect of different air volume is smaller.

This is only a rough algorithm, the specific numbers to be combined with specific models, speed, road conditions to calculate.

Let's assume your car city commutes with a comprehensive calculation of 10 liters of oil. The average 25 km per day is calculated by car:

Open 25 km = fuel consumption 2.5l=14.9 yuan (5.96 yuan/Liter); air-conditioning fuel consumption 3l=17.88 yuan: more than 2.98 yuan

25 km open an air-conditioner and spend a bottle of coke money. So, save a little money is not enough to buy a bottle of Coke solution.

Less than 60 km/h try not to turn on the air conditioner

Although air-conditioning increases fuel consumption, but the high temperature most owners are really inseparable from air conditioning. How to use air conditioning can be more fuel-saving? Here are some tips from professionals: First of all, keep in mind the "60/80 rule". When the vehicle travels at an hourly speed of less than 60 km, if the weather is not stuffy to the non-open air conditioning, you can choose to open the window ventilation. Air-conditioning is more than 80 kilometers per hour, relatively less fuel-consuming. So run at high speed, do not worry about the increase in fuel consumption to open the window "pull the wind."

Second, many people open air conditioning like cool to the end, the temperature is set to the lowest, which will increase fuel consumption. Because the temperature setting is low, the air-conditioning pump will continue to operate, the blower will be in the high-grade wind, increased the load of the car, not to the purpose of fuel-saving. Generally speaking, the interior temperature of the car is less than 5 ℃, otherwise it is uncomfortable after the car and outside contact.

Again, the summer car temperature is high, the car immediately after the air conditioning not only the cooling effect is not good, but also will increase the engine in the initial operation of the pressure, it is best to open the door after all the windows opened, and so the car inside the temperature significantly reduced after the air conditioning. and arrived at the destination, after the shutdown of the air conditioning, is also very harmful to the engine, to develop the car before the air conditioning, audio, lighting and so all the habit of shutting down.

Finally, do not forget to film to cool down, the sun block outside. The solar film can effectively block the heat energy, control the interior temperature, save the automobile air-conditioning fuel consumption, but also can achieve the efficiency of fuel saving and energy conservation.
