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 what we commonly call "8 oil".
Extended data:
Actual calculation method of fuel consumption per 100 kilometers: X/ 100=50/600, where x is the actual fuel consumption per 100 kilometers, and the right side of the equation is the fuel consumption of 50L when the vehicle travels 600 kilometers. Solve the equation, X=50× 100/600.
Answer: X≈8.33
Therefore, the actual fuel consumption of the car is about 8.33L per 100 kilometers.
If the engine speed is controlled within the same safe speed, the fuel consumption per hour is the same regardless of the vehicle speed. The first two specifications are not suitable for calculating the oil consumption in expressway and engineering transportation, and it is more accurate to calculate the oil consumption per hour. Calculation formula of fuel consumption per hour: fuel consumption per 100 kilometers/100* limit *0.8 (the limit speed is the highest safe speed).
