How to save fuel by driving a walker?

Generally speaking, manual transmission is more fuel-efficient than automatic transmission, but if the driving mode is not good, both manual transmission and automatic transmission are very fuel-intensive.

1. Keep the economical speed: the economical speed of common manual transmission models is mostly 60 ~ 90km/h. Depending on the models, car owners can also consult professionals in "4S" stores. In this speed range, the vehicle is the most fuel efficient. In addition, the speed limit in expressway in China is generally below120km/h/h. Besides the quality problem in expressway, this speed limit also has its saving side, because speeding will also bring high fuel consumption.

2. We should strengthen the maintenance of the car at ordinary times: the wheel bearings should be oiled on time, which can reduce friction and fuel consumption, and the viscosity of the oil will also increase fuel consumption. Use 10W-30 engine oil in winter.

3. Abnormal operation of chassis engine will also lead to high fuel consumption: abnormal tire wear or unstable direction will lead to high fuel consumption.

4. Reduce the weight of the car body: The heavier the car body, the greater the engine load and the higher the fuel consumption. In short-distance driving in cities, some unnecessary loads can be removed.

5. Avoid frequent sudden acceleration and sudden braking, and keep driving at a constant speed.

6. The idle speed of cold cars is high in winter, and the time is longer than that in summer, which will also lead to high fuel consumption.

7. Don't warm up the car at idle speed: If you go out in the morning and are used to starting the engine and let the car warm up for a few minutes, don't do it again. Idle parking and preheating will consume a lot of fuel and make the engine stall. After all, cars now don't need carburetors, and they don't need to pull the throttle to heat the car as before. The correct way is to warm the car while driving. As long as the speed is not too fast, the engine can reach the working temperature after driving for one or two kilometers.

8. Fill with high-quality gasoline. Impurities such as wax and colloid in gasoline are the main components of carbon deposition, so the carbon deposition tendency of high cleanliness gasoline is weak. It should be noted that high grade does not mean high quality, that is to say, 97 # oil is not necessarily less than 93 # oil, and grade only represents the octane number of the oil, not the quality and cleanliness. In order to ensure the cleanliness of gasoline, some car owners will adopt the practice of adding gasoline detergent to gasoline. This can effectively prevent the formation of carbon layer on metal surface, and gradually activate the original carbon particles to be removed slowly, thus protecting the engine from damage. However, the addition of gasoline detergent must be cautious. If counterfeit and shoddy products are added, it will have the opposite effect.

9. Don't change the tire size at will. Choosing wider tires may make your car look more "sports car", but the wider the tires, the greater the wheel resistance, so unless you really need extra grip, you are just wasting gas money. In addition, insufficient inflation and excessive wear of tires will increase fuel consumption. If the sliding distance is obviously shortened during driving, it is necessary to check whether the tire pressure is up to standard.

10. Take good care of yourself. The dent in the car body will increase the airflow resistance encountered when the car is driving. Besides, those flashy decorations will only increase resistance, so just take them off.

1 1. On the highway, it is better to turn on the air conditioner than to open the window: it seems to be a well-known common sense that using the air conditioner will increase fuel consumption, but there are also cases where not using the air conditioner will also increase fuel consumption. When the vehicle speed exceeds 85km/h, opening the window will bring resistance and even offset the fuel consumption caused by turning on the air conditioner. Therefore, when driving at high speed, use air conditioning system.
