How is the comprehensive fuel consumption calculated?

[StSarah]

Comprehensive fuel consumption is calculated as follows: 1. The Ministry of Industry and Information Technology adopts an indirect measurement method. For light-duty vehicles, the entire vehicle is placed on a test bench to simulate the actual driving speed and load on the road, operating under certain conditions (such as idling, acceleration, etc.), measuring the emissions of carbon dioxide, carbon monoxide, and hydrocarbons, and calculating fuel consumption using the carbon balance method. The vehicle is operated under various conditions including idling, deceleration, gear shifting, acceleration, and constant speed. 2. The formula for comprehensive fuel consumption: Fuel consumption per 100 kilometers = Volume of fuel (liters) ÷ Distance the vehicle can travel with that fuel (kilometers) × 100.

Calculating the comprehensive fuel consumption isn't actually that complicated. Here's how I do it: Every time I refuel, I fill up the tank completely and note down the mileage. When it's time to refuel again, I fill up the tank once more and record how many liters of fuel were added and how many kilometers were driven. Simply divide the amount of fuel added by the distance traveled and multiply by 100 to get the fuel consumption per 100 kilometers. I've found this habit quite useful—not only does it help monitor fuel expenses, but it also reveals the impact of my driving habits. For example, rapid acceleration and frequent braking can cause fuel consumption to spike, so I try to maintain a smooth speed. I also check the tire pressure, as insufficient pressure can significantly increase fuel consumption. Since adopting this habit, the money I save on fuel each month is enough for a hot pot meal.

To calculate comprehensive fuel consumption, I think it's a good idea to start by understanding the official testing methods. Manufacturers typically simulate two scenarios in the lab: urban congestion and highway cruising, to derive average fuel consumption values. But actual measurements are more reliable: I use a notebook or mobile app to record each refueling amount and mileage, then calculate the average after driving about a thousand kilometers. There are many influencing factors, such as running the AC at full blast can increase fuel consumption by 10% to 20%, so I try to use it less on cloudy days. I've also found that regular maintenance like changing engine oil and air filters can help stabilize fuel consumption. These details combined make the calculation more than just a numbers game—it also helps optimize daily driving habits.

I pay attention to fuel consumption not just to save money, but also for its environmental significance. The calculation is simple: divide the total amount of fuel refilled over a period by the total mileage and multiply by one hundred. After calculating the fuel consumption per 100 kilometers, you can also estimate the carbon footprint—approximately 2.3 kilograms of carbon dioxide emitted per liter of gasoline. Therefore, regularly calculating fuel consumption makes me more conscious: maintaining a speed of around 80 km/h and reducing unnecessary idling can both reduce pollution. Walking more or carpooling in daily life is also crucial. Such small changes, when accumulated, contribute significantly to the environment.

Modern methods make calculating fuel consumption super convenient, and I love using mobile apps to get it done. Install apps like Drivvo or GasBuddy, scan the QR code and input the numbers every time you refuel, and it automatically calculates the average fuel consumption. It even compares urban and highway data. The car's onboard system sometimes displays it directly, but the error margin can be significant, so manual cross-checking is more accurate. I also enjoy testing different road sections during trips and found that suburban roads save nearly 30% more fuel. Setting up app reminders for refueling times and fuel consumption changes is incredibly practical—saves me from memorizing a bunch of data.

I've been calculating comprehensive fuel consumption for half my life. In the past, I manually calculated it using gas station receipts, but now the onboard computer does it with a single click. However, the principle remains the same: averaging urban and highway fuel consumption. During testing, fill up the tank, drive a fixed route, then refuel to measure, avoiding excessive uphill driving or changes in load. Engine health is fundamental—regular oil and filter changes keep fuel consumption stable and prevent increases. Safety first is also crucial; steady driving without speeding reduces accidents and makes fuel consumption more economical.
