Tip 1: Car "slimming"
There is no doubt that the heavy load of a car will definitely increase the fuel consumption of the car during driving. Therefore, we must always remember to "reduce the burden" on the car. Don't load too many unnecessary items in the car at ordinary times. For example, some car owners often put several boxes of mineral water in the trunk for convenience. Actually, it is very convenient to buy mineral water. You can buy three or five bottles at a time. Some car owners don't get into the habit of cleaning the trunk frequently. Some temporary items are often left in the trunk for a long time. Over time, it will form a great burden.
In fact, it is very important to form the habit of cleaning the car frequently. Extra things, whether it is a pair of sports shoes or half a can of engine oil, will increase the load of the car. Statistics show that the fuel efficiency of the car is 2% lower than that of the light car when it is overloaded with 45 kg, thus losing 1% gasoline mileage. In addition, try not to put anything on the roof. The wind resistance caused by a piece of luggage or a full roof rack will reduce the gasoline mileage by 5%. If possible, put things in the car.
Tip 2: Flexible shifting
Usually, manual transmission is more fuel efficient than automatic transmission, but this is not absolute. Whether it is manual or automatic, it is very important to master the shifting skills flexibly. If the owner is driving a manual transmission car, he should shift the 1 gear to the second gear as soon as possible after starting. When the speed is 30 km/h, the second gear can be changed into the third gear, when the speed is 40 km/h, it can be changed into the fourth gear, and so on. When the speed is 50 km/h, it becomes the fifth gear. At the same time, in the whole driving process, don't step on the accelerator to the end, you should ensure that the accelerator is between 50% and 70%.
In the case of a red light, you should put in neutral, loosen the throttle and clutch, and let the car achieve zero fuel consumption. If there is a car ahead and the car is stopping slowly, you should also use neutral to let the car stop slowly by inertia.
If the owner is driving an automatic car, he should raise the gear to the highest gear as soon as possible after the starting action is completed, and can keep the locked state at this time. During driving, slowly release the throttle to complete the upshift operation. If you need to downshift, step on some accelerator deeply to realize the gear upgrade of automatic transmission models.
Skill 3 scientific operation
With the rapid development of automobile industry technology, various auxiliary functions in automobiles are becoming more and more complete. However, the use of these auxiliary functions is often at the expense of increasing fuel consumption. Scientific and reasonable operation can also bring certain fuel-saving effect. For example, during driving, try to reduce or turn off unnecessary electrical appliances, such as air conditioners, stereos and electrically heated seats. However, when driving on expressway, you should close the windows and use air conditioning, because once the speed exceeds 75km/h, in order to overcome the air resistance, the fuel consumption of the car will be 1.5 times of the economic driving speed. Opening the window will have a negative impact on fuel consumption.
It is also important to keep the best speed in combination with the road conditions. Generally speaking, the lowest economic driving speed is 50 to 60 kilometers per hour. Acceleration is the most fuel-intensive. The smoother driving, the less braking times, the less acceleration times, and the more fuel-efficient. In addition, if you step on the accelerator to the end, the fuel consumption may be twice as high as usual. If you are at an intersection with a particularly long red light, you'd better turn off the engine and try to avoid idling. Because the fuel consumption of the engine idling for 3 minutes can make the car travel 1 km.
