Car economy refers to the ability to complete a unit of transportation work with minimal fuel consumption. There are three evaluation indicators for economy: fuel consumption per unit of mileage, fuel consumption per unit of transportation workload, and mileage traveled per unit of fuel consumed.
Chinese name. Car fuel economy.
Foreign name. automobile fuel economy
Overview. Generally, it is expressed in terms of fuel consumption or oil stroke.
Function. Fuel consumption indicators for automobiles.
Mensuration. Driving test and constant velocity fuel consumption test.
Fast. Navigation.
The assay affects how to improve.
Fuel consumption refers to the volume of fuel required per unit mile when the car is fully loaded. Both China and Europe are expressed by the number of fuel consumed by driving 100 kilometers (L), that is, L 100 km; Fuel stroke refers to the mileage that can be driven per unit volume of fuel when the car is fully loaded, and the United States is expressed in terms of the mileage that can be driven per gallon of fuel, that is, m ile gal (mile gallon).
In the former notation, the smaller the value, the better the fuel economy; In the latter notation, the higher the number, the better the fuel economy (conversion relationship: 1 gallon = 4.).546 l, 1 mile = km).
The fuel economy index of gasoline is related to the characteristics of the engine and the weight of the car, the speed of the vehicle and the size of various motion resistances such as air resistance, rolling resistance and climbing resistance, the efficiency of the drive train and the reduction ratio, so the values are often different from the actual situation.
Determination rules. There are two methods for determining the fuel economy of automobiles: one is the driving test method; The other is to carry out a constant velocity fuel consumption test on a flat road and under certain conditions.
When carrying out the vehicle road test, the main instrument applied is the vehicle road tester, which uses the photoelectric road surface detector installed on the car to irradiate the road surface, converts the road surface image into a frequency signal, and finally reflects the distance traveled by the car, and then gives the speed of the vehicle at different times through its internal timer. When the fuel consumption test is carried out, it is equipped with a flow sensor to measure the fuel consumption of the vehicle at any time and at any speed.

QashqaiFuel consumption is shown to be throughAutomotive instrument panelsA meter display switch key on the left side to switch Mu Xun, every time you press this button under Changsui, ** The meter display will change, and the specific operation steps are as follows:
1. Press the Qashqai's brake pedal. 2. Press the Qashqai's one-button start button. 3. The Qashqai's instrument lights up, and the power supply of the whole car is turned on.
4. Press the Qashqai's instrument function display toggle key. 5. Display the average speed in turn. 6. Average fuel consumption.
Qashqai, which means "urban nomad". Qashqai is Nissan.
The first creation since the establishment of the European Design Center, it is positioned between a compact SUV and a hatchback. But unlike the crossovers that are produced directly on the sedan platform, the Qashqai is a product specifically designed by Nissan for this unique segment of the Xunzheng market.
As a real urban driving SUV, Qashqai started from the integration of multiple functions at the beginning of the design, absorbed the characteristics of SUVs and sedans, optimized and balanced the appearance, interior, handling, comfort and other aspects of the body, and refined the core product strength, which is the representative model of the hot-selling SUV - as of 2018, the cumulative global sales exceeded 4.6 million, and the cumulative sales in China exceeded 1.1 million.

Press and hold the setting button on the dashboard to switch between instantaneous fuel consumption and average fuel consumption, I wish you a happy car!
Good driving habits can not only reduce fuel consumption, but also extend the service life of the vehicle. Master Zhang, who has many years of experience in driving and repairing, said that in fact, good driving habits are easy to develop, according to his experience, as long as the driver pays attention to mastering some "small actions" in the process of controlling the vehicle, he can receive a good fuel-saving effect.
Hello: For the instantaneous fuel display of the Dongfeng Nissan Qashqai model, its fuel economy works like this: the average fuel consumption display, indicating the fuel consumption after the resetting, the average fuel consumption value is automatically refreshed every 30 seconds or every 500 meters, which is an instantaneous fuel consumption display.
1. Soft start: Start in low gear, slowly press the accelerator pedal, and accelerate slowly. When the car reaches a certain gear speed, learn to listen to the sound of the engine and gradually shift the gear from low to high.
Second, the use of economic speed: the economic speed of the general car is between 60km h and 80km h. It is most fuel-efficient when the car is running at an economical speed.
3. Light. Engine oil and gasoline are not the same thing, okay. Fuel consumption information shows the number of gasoline consumed per 100 kilometers, not the oil.
For this situation is normal, the Qashqai model uses a journey computer display system, and its fuel economy works like this: the average fuel consumption display, indicating the fuel consumption after the resetting, the average fuel consumption value is automatically refreshed every 30 seconds or every 500 meters, which is an instantaneous fuel consumption display.

The average fuel consumption of the new Qashqai is in liters per 100 km. Qashqai is a compact SUV owned by Dongfeng Nissan, and its entire range is equipped with a naturally aspirated engine and a CVT gearbox.
Fuel consumption per 100 kilometers is the amount of fuel consumed per 100 kilometers, and the fuel consumption per kilometer can be calculated as, according to the latest oil price, if you add 92 gasoline, the current oil price is yuan l, then the fuel cost per kilometer is: yuan l = yuan, that is, about yuan kilometers.
If you add No. 95 gasoline and the current oil price is yuan l, then the fuel cost per kilometer is yuan l x = yuan, that is, about yuan kilometer.

Does it mean by "what does the Qashqai fuel consumption meter display" mean? The return section refers to the actual oil consumed per 100 kilometers.
The factors that affect the fuel consumption of a car are as follows:
1. Drop the weight of the vehicle. The relationship between vehicle weight and fuel consumption is directly proportional, and it is said that for every 10% reduction in vehicle weight, fuel consumption may also be reduced by a percentage point.
2. Car styling. The drag coefficient of the body is small, and the fuel consumption will be significantly reduced. The connection between the two is also directly proportional;
3. Improve the thermal efficiency of the engine. At present, the thermal efficiency of most gasoline engines (that is, the proportion of fuel converted into useful work) has reached more than 30%, while the diesel engine has exceeded 40%, which means that the fuel consumption of diesel engines is lower than that of gasoline engines.

1. Air intake system (1) When the intake manifold or various valves leak when the air, gasoline vapor and combustion exhaust gas that should not enter enter the intake manifold, the mixture is too thick or too thin, and the engine burns abnormally. When the leakage position only affects individual cylinders, the engine will shake more violently, which will have a greater impact on the idle speed of the cold car. Common causes are: >>>More
