When buying a car, the fuel consumption per 100 kilometers on the dashboard often becomes one of the important indicators for us to measure the performance of the car. However, have you ever wondered why there is a big difference between the fuel consumption in actual driving and the fuel consumption of 100 kilometers on the dashboard?
The calculation method of fuel consumption per 100 kilometers on the dashboard
First of all, we need to understand the calculation method of fuel consumption per 100 kilometers of the dashboard. Generally speaking, the fuel consumption per 100 kilometers on the dashboard is tested under ideal conditions, including factors such as driving at a constant speed, good road conditions, and suitable climate. However, in actual driving, we often face more complex situations, such as congestion, rapid acceleration, air conditioning use, etc., which may cause the actual fuel consumption to be higher or lower than the fuel consumption of 100 kilometers on the dashboard.
Factors that affect fuel consumption
1. Vehicle weight and load
The dead weight and load of the vehicle have a direct impact on fuel consumption. Generally speaking, the greater the dead weight of the vehicle, the more power it needs to drive, which in turn leads to higher fuel consumption. In addition, when the load of the vehicle increases, it also increases the burden on the engine, resulting in higher fuel consumption.
2. Driving Xi and road conditions
Driving Xi and road conditions also have a significant impact on fuel consumption. Bad driving Xi such as hard acceleration and sudden braking will keep the engine under high load for a long time, resulting in increased fuel consumption. In addition, driving on congested city roads for long periods of time can also increase fuel consumption.
3. Air conditioning use and climatic conditions
Air conditioning usage and climatic conditions are also among the factors that affect fuel consumption. In hot summers or cold winters, the turn on of the air conditioner or heater can increase the burden on the engine, resulting in higher fuel consumption. In addition, extreme weather conditions such as high temperatures and humidity can also have an impact on fuel consumption.
The difference between the actual fuel consumption per 100 kilometers and the fuel consumption of the dashboard per 100 kilometers
After understanding the factors that affect fuel consumption, it is not difficult to understand why there is a difference between the actual fuel consumption per 100 kilometers and the fuel consumption of the dashboard per 100 kilometers. In actual driving, due to the influence of various complex factors, such as road congestion, rapid acceleration, air conditioning use, etc., the actual fuel consumption may be higher or lower than the fuel consumption of 100 kilometers on the dashboard.
How to reduce the actual fuel consumption of 100 kilometers
Since there is a difference between the actual fuel consumption of 100 kilometers and the fuel consumption of the dashboard 100 kilometers, what methods can we use to reduce the actual fuel consumption of 100 kilometers? Here are some practical suggestions:
1. Plan your route reasonably: Before traveling, try to choose a smoother road to avoid long-term congestion. At the same time, the route should be reasonably planned to reduce unnecessary fuel consumption and waste caused by detours and repeated driving.
2. Improve driving Xi habits: Develop good driving Xi habits, such as smooth acceleration, deceleration, and avoiding sudden braking, which can effectively reduce fuel consumption. In addition, proper control of the speed of the vehicle within the economic speed range can also reduce fuel consumption.
3. Reduce vehicle load: In the process of driving, minimize unnecessary loads, reduce the burden on the vehicle, and reduce fuel consumption.
4. Rational use of air conditioner: In hot summer or cold winter, try to avoid turning on the air conditioner or heater for a long time, so as not to increase the burden on the engine and lead to an increase in fuel consumption.
5. Regular maintenance of the vehicle: Regular maintenance of the vehicle, such as changing the engine oil, cleaning the air filter, etc., can keep the vehicle in good condition and improve fuel efficiency.
Rationally look at the fuel consumption of the dashboard per 100 kilometers
From the above analysis, we can conclude that the fuel consumption per 100 kilometers on the dashboard is the data obtained by testing under ideal conditions, while the situation in real driving is often more complex and changeable. Therefore, in actual driving, we need to rationally look at the data difference of fuel consumption per 100 kilometers on the dashboard, and take measures to reduce the actual fuel consumption per 100 kilometers according to the actual situation. Only by taking into account a variety of factors can the performance and economy of a vehicle be more accurately assessed.
