Knowledge sharing of automobile use-reducing fuel consumption

High fuel consumption when starting and accelerating. When driving a vehicle, try to avoid stepping on the accelerator and start with 1. Frequent starting is the main reason for high fuel consumption. We can't change the number of starts, but we can effectively reduce fuel consumption by starting slowly.

Maintain economic speed

The average road speed is 40-60 km/h, and the expressway speed is 80-100 km/h. Under the premise of safety, it is more economical to keep the economic speed unchanged.

Correct gear shift

When driving, don't let the engine run at unnecessarily high speed. Drive in high gear as far as possible, and only when the engine is not running smoothly, put in low gear. Cars equipped with automatic gearbox should slow down the accelerator pedal when accelerating, and the gearbox should choose an economical shift procedure, shifting to high gear in advance and then to low gear, thus reducing fuel consumption. When stopping or slowing down, use the inertia of the vehicle as much as possible to save fuel. The shift of manual transmission vehicles needs to be carried out within a suitable speed range (2000-2200 rpm); It can also be done according to the shift prompt information on the instrument cluster.

Keep the wind resistance of the vehicle low.

When driving at high speed, a large part of power is used to overcome wind resistance. So try not to install the roof or make unreasonable modifications. It is estimated that adding a luggage rack to the roof will increase fuel consumption by 5%. On the highway, don't think that opening the window will save fuel than turning on the air conditioner. Opening a window will greatly increase air resistance, but it will consume more fuel. Please close the window when the vehicle speed is higher than 80 km/h.

Maintain the correct tire pressure

Check the tire pressure regularly. If the tire pressure is too low, the tire rolling resistance will increase and the fuel consumption will also increase. Economic driving tire pressure: 2 10-250kpa.

Don't blindly use power-consuming equipment

Please use power-consuming equipment according to actual needs, and don't blindly use it to increase fuel consumption. The power consumption of the rear windshield heater, auxiliary headlights, blower and air conditioning system is quite large, which will increase the load of the generator and increase fuel consumption. For example, if the rear windshield heater is used for 10 hour, the fuel consumption of the whole vehicle will increase 1.0 liter.

Reduce vehicle load

Every extra kilogram of weight may increase fuel consumption, and clean up unnecessary luggage on the car regularly.

Perform regular maintenance.

Do maintenance according to the specified time and keep the vehicle in good condition (the first maintenance time is 5000 kilometers or three months, whichever comes first). Carbon deposits in engines, throttles and nozzles, as well as oil passages, may increase fuel consumption.
