Cold weather and high fuel consumption.

Recently, many places in the country have ushered in sharp cooling and rain and snow weather, and some areas have issued snowstorm warnings. With the arrival of cold weather, automobile fuel consumption will also increase. Today, I will talk to you about how to save fuel when driving in winter ~ Master these fuel-saving tips and easily become a fuel-saving god!

First, correct and timely add and subtract files

With the increase of engine speed, the fuel consumption of the vehicle will naturally increase sharply, so you can shift gears according to the reasonable speed and gear of the vehicle. Of course, when the vehicle speed is too low and the gear is still high, the engine and the body will start to shake and may stall at any time. Increasing the throttle means that the fuel injection will increase. Therefore, low-grade high-speed or high-grade low-speed driving is not desirable, and timely and correct downshifting is conducive to reducing vehicle fuel consumption.

Second, step on the accelerator and brake slowly.

It is very undesirable to slam on the accelerator and brake. If you refuel quickly and brake frequently during driving, the carbon monoxide emission per kilometer will increase by 0.4 grams. You should develop good driving habits, refuel slowly, drive at a constant speed, and don't change lanes at will. Over time, you can save a lot of gasoline. Also, it is best not to overtake or change lanes frequently when driving. Driving at a constant speed can reduce fuel consumption.

Third, turn off the fire when it is time to turn it off.

When the engine is started, the fuel injection from the nozzle is relatively large, so it is best to avoid starting the engine frequently for a period of time. However, when there is traffic jam and waiting for a parking space for a long time (more than 3 minutes), it is best to turn off the vehicle, which can not only reduce exhaust emissions, but also save fuel. In addition, when the water temperature is too low, the vehicle will inject more fuel, and the water temperature will not rise to normal in cold weather. Short-distance driving in winter is not recommended.

Fourth, use air conditioning in a timely and appropriate manner.

When driving at low speed, you can open the window to ventilate and cool down, but it is more cost-effective to turn on the air conditioner when driving at medium and high speed. Of course, there are also on-board electrical appliances, such as radio, air conditioner, window heating system and so on. , are supplied by oil consumption. Turn off these devices when you get off the bus to avoid turning them on automatically when you start the car again, which will increase fuel consumption.

Fifth, add engine oil reasonably.

If the vehicle is not maintained in time, it will lead to more pollution (high emissions), so it is necessary to check and maintain the vehicle regularly and change the lubricating oil. Viscosity is the main index of engine oil. High viscosity engine oil will increase the resistance of engine parts, which will not only consume power but also increase fuel consumption.

For example, 15w-40, where "w" stands for winter, the smaller the number in front of it, the lower the viscosity and fluidity of engine oil, the lower the available ambient temperature, and the better the engine protection ability during cold start; The number after "W" is the index of high temperature resistance of oil. The larger the number, the better the protective performance of oil at high temperature. The quality of fuel is directly related to the running state of vehicles and the total amount of pollutants discharged, so try to refuel at regular gas stations.

Six, maintain normal tire pressure or size.

When the tire pressure is insufficient and the selected tire is too wide or too large, the driving resistance will increase, thus increasing the fuel consumption of the vehicle. On the contrary, it will increase the possibility of puncture and eccentric wear of tires and reduce driving comfort. So be sure to use the correct tire pressure to match the original tires. Experiments show that the fuel consumption will increase by 5% ~ 10% when the car runs at a speed of 40 kilometers per hour under the condition of insufficient tire pressure.

Seven, regular cleaning of vehicles

The biggest resistance when the vehicle is driving comes from the air. Even a slight bump or sag in the car body will affect fuel consumption, and too much dirt on the car body is also a burden on the vehicle. It is also a fuel-saving method to clean the appearance of vehicles and wax them regularly.

Eight, moderate decoration to the car "burden"

The fuel consumption of the vehicle will increase with each additional weight, and the extra large coaming, tail wing, winch and luggage rack will increase the fuel consumption of the vehicle. Therefore, in order to reduce fuel consumption, please give up these actions appropriately and "reduce the burden" on the vehicle.

9. Plan the travel route in advance to avoid congested road sections.

Reduce the start and stop of vehicles and drive at an economical speed, which is equivalent to saving fuel. Acceleration, deceleration or lane change will also increase fuel consumption to some extent. Therefore, it is also one of the tips to save fuel by planning the driving route in advance before driving and avoiding congested sections.
