What does the Φ symbol displayed on the car mean?
1 Answers
The Φ symbol displayed on the car represents the average fuel consumption. Average fuel consumption generally refers to the combined fuel consumption, which is the average value of fuel consumption under several different road conditions under specific circumstances. Typically, the combined fuel consumption is 'calculated' based on fuel consumption in both urban and suburban conditions. The basic calculation method is to divide the actual fuel consumption by the actual distance traveled. That is, fuel consumption per 100 kilometers = fuel consumption (liters) ÷ distance traveled (kilometers) * 100. The following are the reasons for high fuel consumption: 1. Improper driving habits: The amount of fuel consumption is closely related to the driver's personal driving habits, specifically manifested in not turning off the engine during long idling or frequent ignition, aggressive acceleration or frequent braking while driving, driving at low gear with high speed or high gear with low speed, etc. All these driving habits greatly 'contribute' to increased fuel consumption. 2. Abnormal tire pressure and tire wear: If the tire pressure is too low, the friction between the tires and the ground increases, resistance becomes greater, and fuel consumption will rise. Normal tire pressure is around 2.5bar, which can be appropriately reduced by 0.1bar in summer; of course, the tire pressure should not be too high either, and it is best to inflate according to the vehicle's standard value. In addition, if the tires are severely worn, slipping will frequently occur, and fuel consumption will also increase. 3. Fuel quality and carbon deposits: Many car owners do not pay attention to fuel quality. Poor-quality gasoline will increase carbon deposits, and excessive carbon deposits will roughen the intake pipe walls, affecting the intake effect and the quality of the air-fuel mixture, leading to a sharp increase in fuel consumption. Therefore, the quality of gasoline cannot be ignored; thus, regular maintenance at a 4S shop is a forward-looking investment, not only ensuring the normal performance of the vehicle but also saving unnecessary expenses in the future.
