What is the fuel consumption calculation formula per kilometer?
2 Answers
Fuel consumption calculation formula: Fuel consumption x fuel price / 100 kilometers. This way you can calculate the cost per kilometer. For example, if the fuel consumption is 9 liters and the fuel price is 7.5 yuan per liter, 9 multiplied by 7.5/100 = 0.675 yuan, which means the fuel cost per kilometer is 0.675 yuan. Let me explain what fuel consumption is. Fuel consumption (L/100Km): commonly referred to as the amount of fuel a car consumes after traveling 100 kilometers. For example, when people say 8 liters or 9 liters, they mean 8 liters or 9 liters per 100 kilometers. If you want to calculate the cost per kilometer, you can do that too. The actual method to calculate fuel consumption is to fill up the tank and note your odometer reading. The next time you fill up, note the amount of fuel added and the current odometer reading. The amount of fuel added divided by the difference in odometer readings gives the fuel consumption per kilometer. Multiply this number by 100 to get the fuel consumption per 100 kilometers, which is what people mean when they say "8 liters." Fuel consumption per 100 kilometers refers to the amount of fuel a vehicle consumes when traveling 100 kilometers on the road at a certain speed. It is a theoretical indicator of the vehicle. The fuel consumption per 100 kilometers is a value measured by the manufacturer in an objective environment using a dynamometer installed on the vehicle's chassis, converted into speed parameters, and then calculated under specified speed conditions to determine the theoretical experimental fuel consumption per 100 kilometers for the vehicle model. Road condition fuel consumption is a fuel indicator calculated by repeatedly testing the vehicle's fuel consumption under specified road conditions, speeds, and times. It is also called multi-condition road cycle fuel consumption. The standard specifies that each cycle includes various driving conditions and records driving conditions based on specified shift times, parking times, driving speeds, acceleration, braking, and deceleration. The values obtained by this method are closer to actual values. Fuel consumption per 100 kilometers is an indicator of the vehicle, while road condition fuel consumption is a standardized statistical method. Within the economic speed range, the slower the vehicle travels, the higher the fuel consumption per 100 kilometers. Beyond the economic speed, the opposite is true. If the engine speed is controlled within the same safe range, the hourly fuel consumption remains the same regardless of the vehicle's speed. For calculating fuel consumption on highways and in engineering transportation, the first two methods are not suitable; calculating hourly fuel consumption is more accurate. The hourly fuel consumption calculation formula is: fuel consumption per 100 kilometers / 100 * limit * 0.8 (limit speed is the highest safe speed).
After driving for so many years, I've found the formula to calculate fuel consumption per kilometer is quite simple: just divide the fuel consumption per 100 kilometers by 100. For example, if my car consumes 10 liters per 100 kilometers, then it uses 0.1 liters per kilometer. To calculate it accurately, I usually fill up the tank, note the mileage, drive about 100 kilometers, refuel, and divide the amount of fuel used by the distance traveled. For instance, if I use 5 liters of fuel for 50 kilometers, that's 0.1 liters per kilometer. However, many factors affect fuel consumption, like city traffic which can double it to 15 liters per 100 kilometers (0.15 liters per kilometer), while on highways it might drop back to 8 liters per 100 kilometers (0.08 liters per kilometer). Maintenance can also save money: keeping tire pressure optimal, regularly changing filters, and using high-quality engine oil can reduce fuel consumption by 10% over a year. Using the air conditioning heavily in summer or preheating the car in cold winters can increase fuel consumption by 10%. These small details shouldn't be overlooked. Understanding this formula not only saves money but also extends the car's lifespan.
