Why is the average fuel consumption of my 14 generation sylphy 12.5km?

The increase of automobile fuel consumption will be affected by many factors, such as vehicle weight, road congestion, driver's driving habits, turning on air conditioning and so on. So Sylphy's fuel consumption is getting higher and higher. What is the reason for changing from 7 to 10? Let's take a look.

Reasons for the increase in fuel consumption of Sylphy:

1. Long-term maintenance of the vehicle: Long-term maintenance of the vehicle will lead to dirty engine oil and air filter elements, and dirty engine oil will lead to poor lubrication and increase the resistance of all moving parts of the engine. More energy is needed to overcome resistance and fuel consumption will increase.

2. Insufficient tire pressure: Insufficient tire pressure will increase the contact area between the tire and the ground and increase the friction, that is, the driving resistance will increase, thus increasing the fuel consumption of the car.

3. Too much carbon deposit in the vehicle: Too much carbon deposit in the engine will lead to insufficient combustion when the engine is running, which will lead to an increase in fuel consumption.

4. Affected by temperature: Temperature will lead to fluctuations in fuel consumption, and when the temperature is low in winter, fuel consumption will increase.

5. Dirty throttle valve plate: Dirty throttle valve plate will lead to inaccurate valve plate opening, and more air will enter the engine, which will lead to increased fuel injection and fuel consumption.

6. Long-term idling without flameout or frequent ignition: when driving, the accelerator is slammed and the brakes are frequent, the vehicle increases the load without any reason, and the vehicle drives at a low speed or a high speed. In summer, the windows are fully opened and the air conditioner is turned on when there is traffic jam.

7. Incorrect sensor data: The sensor is not completely damaged, but the data is inaccurate. If the oxygen content displayed by the oxygen sensor is too high, or the temperature sent by the water temperature sensor is too low, it will lead to an increase in fuel injection, incomplete combustion and increased fuel consumption.
