How fuel-efficient car, and the voice of the majority of riders are often hot topic. Today I will teach you the recipe, so you save a year of oil money, you can buy an iPhone XS.

1, the optimal rotational speed control

Running the engine revolution speed is generally in the most suitable vehicle EFI 1800-2000. No matter which gear, engine revolutions are kept at about 1800-2200.

2, to maintain the optimum speed

The most fuel-efficient driving state is uniform straight, the most fuel-efficient small cars speed is 60-80 km per hour, the car is 80-100 km displacement, when the car is running when the economy is the most fuel-efficient speed.

3, soft start

Downshift started slowly accelerator pedal, slow acceleration. So that when the car reaches a certain speed gear, learn to listen to the sound of the engine to stall and gradually change from low to high. This can reduce engine warm-up time, increase the utilization of fuel. If the boom starts to speed up the throttle, it will not only hurt the car will greatly increase fuel consumption.

4, Qingtai throttle

Qingtai throttle fuel-efficient. If the lift Meng throttle, the engine speed will cause the sudden decrease in traction resistance play a role in part offset with inertia, and automobiles produce "chatter", the fuel consumption increases.

5, reduction in the braking

Braking is essentially an energy conversion process, the energy consumption of the brake means. So through the intersection, downhill, should lift the throttle advance.

6, to maintain normal levels of tire pressure

Insufficient tire pressure, rolling resistance will increase greatly. According to the test, the air pressure is lower than a predetermined value of 2 psi (pressure units: lb/ft2), fuel consumption will be increased by 1?The tire deflection or excessive wear may also cause increased fuel consumption.

Therefore, the best monthly check tire pressure. Moreover, the choice of some green tire, can also reduce the average 3-8?f the fuel consumption.

7, do not fill up the tank

Reduce body weight is to reduce fuel consumption. Do not filled a tank of fuel in the city ran short cut, which is "fuel oil"! Considering the fuel pump mounted in the tank, gasoline-thermal cooling, so without taking a trip, a half tank of fuel is preferably maintained. At the same time, the car must streamline, curbing weight, a provincial oil.

8, a high-speed turn off air conditioning window is especially stupid behavior

Some owners feel always open the window at high speed off the air conditioner is an environmentally friendly behavior. In fact, whenever the vehicle speed exceeds 80km/h, the window will greatly increase air resistance, therefore, at high speed, do not think that would be more than window air conditioners fuel-efficient.

9, timely maintenance

According to statistics, in poor engine fuel consumption increased by 10?r 20?s normal, and the air filter is too dirty, it may lead to increased fuel consumption by 10?In order to maintain optimum performance of the car, the best driving 5,000 km replace the oil once, and check the filter, it is also very important for the maintenance of the car.

10, choose the right pass line

Traffic jams, car fuel consumption is greatest. Therefore, in the big cities should avoid congested road to go. For example, choose a high-speed ring road detour, much lower fuel consumption than the straight road through the city center.

Fuel-efficient car owners are a constant topic, and oil prices going into the eight yuan era, more than 10 fuel-efficient technique to master, I believe, one year you will certainly save a lot of money.
