Although there are many fuel-saving techniques for driving, it is the most important thing to change the driving habits and control of the vehicles. Every action of the control car is natural and smooth, and the speed and speed of the vehicle are smoothly connected, and the starting and stopping actions are accurate and familiar, which is an important factor for fuel economy.
First, keep the optimal speed. The most expensive when accelerating. The smoother the driving, the fewer the number of brakes, the less the number of accelerations, and the more fuel-efficient. In addition, if the driver pushes the throttle to the end, the fuel consumption may be twice as much as usual. The lowest economic driving speed is usually 50 to 60 km / h.
Second, avoid idling. When the engine is idling, the gasoline is also consumed. When the engine reaches about 2,000 rpm to 3000 rpm (the speed of the different models is slightly different), the high gear should be changed in time. If you are waiting at a crossroad with a red light, or a companion in the car, you need to wait. At this time, you should let the engine turn off, try to avoid the engine idling, and the engine will idle for 3 minutes. Kilometers.
Third, pay attention to car weight reduction. Develop the habit of cleaning up the trunk of your car. The extra things, whether it is a pair of sneakers or a half tank of oil, will increase the weight of the car. The car is loaded with 45 kilograms of fuel, and the fuel efficiency is 2% lower than that of the light car. Don’t put anything on the roof. A piece of luggage or a roof rack full of things creates wind resistance and reduces the mileage of gasoline by 5%. If you can, put things in the car.
Fourth, when driving on the highway, the window is closed. After the speed exceeds 75 km/h, in order to overcome the air resistance, the fuel consumption of the car will be 1.5 times that of the economic driving speed. Open windows will have a negative impact on fuel consumption. In other words, turning on the air conditioner may save fuel than opening the window.
