What does comprehensive fuel consumption mean?
2 Answers
Comprehensive fuel consumption is the average value of fuel consumption under several different road conditions in specific situations. Generally, comprehensive fuel consumption is calculated based on fuel consumption in both urban and suburban conditions. Average fuel consumption is defined as the amount of fuel used by a vehicle per unit distance traveled, commonly measured in liters per 100 kilometers. The method to calculate a car's fuel consumption per 100 kilometers: 1. Fill up the fuel tank and reset the small odometer in the trip meter, then drive on the road; 2. When the small odometer reaches approximately 100 kilometers, find a gas station to refuel to the same level as before and record the amount of fuel added in liters; 3. Divide the recorded fuel amount by the mileage on the small odometer and multiply by 100 to get the fuel consumption per 100 kilometers.
The combined fuel consumption is like the overall fuel efficiency performance of a vehicle. It averages the fuel consumption during city traffic jams and smooth highway driving, providing a more comprehensive reflection of the car's fuel efficiency in daily use. As someone who frequently studies cars, I find this figure quite meaningful because it simulates real-world driving conditions through standardized tests, such as stop-and-go traffic, acceleration, and deceleration scenarios. Many factors influence it, including engine performance, vehicle weight, and driving habits. The officially published combined fuel consumption data helps me compare the fuel-saving levels of different models, and referencing this when buying a car allows me to estimate fuel expenses in advance. In actual driving, my experience shows that maintaining proper tire pressure and avoiding frequent hard braking can help keep the actual fuel consumption close to this value, reducing unnecessary expenses. Regular vehicle maintenance checks, such as replacing the air filter, can also optimize fuel efficiency.
