For example, if a car travels n kilometers and consumes one liter of fuel, then the fuel consumption per 100 kilometers = A ÷ n× 100. Bring specific figures. If a car can travel 50 kilometers with 4 liters of oil, then the fuel consumption per 100 kilometers of this car is 4 liters ÷50 kilometers × 100=8 liters/100 kilometers, and the fuel consumption per 100 kilometers is 8 liters, which is commonly known as "8 oil".
Factors affecting automobile fuel consumption
Generally speaking, the displacement of the engine has a certain influence on the fuel consumption of the car, but this influence is a fixed value. Therefore, the displacement of the engine has no great influence on the fuel consumption of the car, and some external factors will affect the fuel consumption of the car.
First of all, talk about the driver's driving habits. The fuel consumption of a car is closely related to the driver's driving habits. If the driver often jerks on or accelerates or decelerates during driving, it will affect the fuel consumption of the car. According to statistics, incorrect driving habits will lead to an increase in car fuel consumption of 5-30%.
The fuel consumption of a car is also directly related to the tire pressure. For vehicles without tire pressure detection display, many car owners often ignore the importance of tire pressure. If the tire pressure is too high or too low, the fuel consumption of the car will increase.
The road condition of the car will also have an impact on fuel consumption. If the car often runs on roads with poor road conditions, the load generated by the engine will increase, so the fuel consumption of the car will naturally increase.
