What Is Economic Speed?

Economic speed refers to the most fuel-efficient driving speed of cars. The economic speed of various models varies. These must be read carefully in the vehicle manual, but they are generally around 90 km / h. Fuel consumption at speeds lower or higher than economic speed Will rise.

Economical speed reduction of automobile fuel consumption

In driving, especially when the traffic is not smooth, driving behaviors such as forcibly overtaking, drilling when you are out of the air, pressing the brakes, and refueling swiftly can also be called fuel killers. When the driver presses the accelerator all the way down, the fuel consumption will increase by 2 to 3 times compared to driving at a constant speed. Once slamming and gradual adding, the same speed, fuel consumption difference can reach 12 ml.

Avoid low-speed and high-speed driving at economic speed

Low-speed high-speed long-distance driving habits mostly occur to beginner drivers. The three-speed long-distance high-speed driving will increase fuel consumption by 10% compared to the fourth-speed normal driving. If the second-speed driving is used instead of the third-speed driving, the fuel consumption will increase. Shifting the engine after the number of engine revolutions exceeds the limit will cause fuel waste. Low-speed and high-speed are definitely fuel-efficient, and high-speed and low-speed are definitely fuel-efficient.

Economical speed check tire system

Insufficient air pressure will increase the friction between the tire and the ground and increase fuel consumption, so check the tire air pressure frequently. Different models and tires have different air pressure standards. You must read the car manual or consult a professional.

Economical speed note frequently check the brake system

Some cars will have slight drag brakes, including hand brakes, which is equivalent to increasing the load of the car while driving and increasing fuel consumption. You can drive the car to a place with a slight slope and good road conditions, step on the brakes, suspend in neutral (in the N gear for automatic transmission), and then slowly release the brake pedal. If the car slips, it means that there is no drag. Brake, you can test the handbrake in the same way.

Clean air filters quickly and economically

Due to the unsatisfactory road conditions, cars driving on large dusty roads for a long period of time can easily cause the air filter to be blocked, making the engine's intake air not smooth, and affecting the mixed combustion of gasoline and air. The carbon deposition speed of the fire nozzle makes the engine ignite smoothly, and the fuel consumption of the vehicle will naturally increase. Therefore, it is recommended that car owners clean the air filter element by themselves at least once a month.

Economical speed reduction of vehicle wind resistance

Excessive decoration, such as the installation of spoiler, rain cover, etc., will damage the wind resistance of the original car design and increase fuel consumption; placing too many unused things in the trunk will also increase fuel consumption. According to reports, each 10 kg increase in load will increase fuel consumption by 1%. In addition, in order to save fuel, some owners take the approach of turning off the air conditioner at high speeds and opening the windows for ventilation, which is highly undesirable.
