Why is the fuel consumption of cars generally higher than the mark on the manual

Manufacturer, at the time of the test run, the test result was 100 kilometers xx liters of straight road. But when we drive, it is impossible to be a straight road everywhere, and there are dozens of traffic lights to commute every day, so the fuel consumption is high

Everyone's driving habits are related, the test is based on 100 kilometers per hour to calculate fuel consumption, but we usually can't drive 100 yards, right?Don't be penalized for going bankrupt.

Hehe, that's theoretical, and it's drawn at a constant speed of 90 kilometers on a professional road. Our daily roads are not as flat as professional roads, and you can probably run at a constant speed of 90 kilometers.

yes, there's something called fuel economy!Theoretical things are not accurate, they are all jokes!Funny for kids!

And then there's the driving skills!

The master will save fuel!

But don't worry, you'll be a master in the near future!

And voila!You can't save oil!

Didn't drive well!When driving, be careful: do not stop when you see a red light.

Practice drifting on the road during the day.

Seeing the traffic police spitting.

Always keep in mind that I am the best.

My lesson: don't speed up;Pay attention to the traffic light change at a long distance and change gears in time;Don't brake suddenly;Don't put useless things in the car and in the trunk;Turn off the engine for more than 2 minutes while waiting for the traffic light to change at the intersection.

The above method works well. In fact, the instructions are much the same, the key is how you open them.

The difference is not big, because the car instrument is displayed according to the actual fuel consumption of the car, although there will be errors, but the gap is not very obvious.

I don't think the difference is big, because this meter is still very accurate, and generally speaking, there will not be much error.

The difference is big. Because the fuel consumption shown by the car meter is 1-2 oils smaller than the actual fuel consumption, I think the difference is big.

If the fuel consumption detected on the top of the user manual, this is the fuel consumption announced by the Ministry of Industry and Information Technology, that is to say, after the automobile manufacturer produces the vehicle, he measures it at a constant speed of 60 80 kilometers per hour. Measure the fuel consumption of the car. Therefore, its fuel consumption must be relatively low, and there is no way to meet this condition in the case of normal driving, so the actual fuel consumption is relatively high in the case of normal driving.

This is the case for every car, and the fuel consumption marked on it is the fuel consumption of the vehicle measured under the condition of normal and uniform speed. There is definitely no way to achieve this condition when using this in daily life, so this fuel consumption is relatively high.

Among the various types of motorcycles, the fuel consumption of scooters is very strange; The body of this model is very light, and the engine is mostly 125cc, with a reasonable thrust-to-weight ratio and such a low displacement, the pedals should be the most fuel-efficient motorcycle. However, the real fuel consumption standard has exceeded many straddles and even recreational vehicles with relatively large displacement, and the measured 250-500cc straddle riders have many vehicles with lower fuel consumption.

The continuously variable transmission used in the car is driven by steel belt or steel chain, and the transmission loss is still large enough, and the steel belt of this material is only used to improve the maximum input torque that can be withheld, to put it bluntly, the engine with a larger displacement is used; However, the wear and tear of the steel belt is very prominent, the replacement cost of belt fracture is not high, especially the scooter is low, but the steel belt and the cone wheel are seriously worn and can only be scrapped and treated. The variable valve timing system can be called VVT or VCT, the variable valve timing system is composed of a solenoid valve (OCV) and a variable camshaft phase regulator (VCT), by adjusting the engine cam phase, so that the air intake can be changed with the change of engine speed, so as to achieve the best combustion efficiency and improve fuel economy.

Motorcycles rev much higher than cars, and it is certain that such high revs cost fuel. In addition, whether the fuel engine is a car or a motorcycle, it always has its basic working principle, that is to say, as long as it burns oil, it will have a minimum value, and it is also for this reason that the fuel consumption of a motorcycle with a small displacement is not equal to the car in terms of displacement. The fuel consumption of a 1800cc scooter is not much different from that of a car of the same displacement.

The subject just changed a concept.

The fuel consumption of a motor vehicle is actually directly related to the driving conditions and engine thermal efficiency, as well as the transmission efficiency of the transmission system (mainly the efficiency of the transmission and reducer system), the windward area (the projection area of the car in front or behind), and the air resistance coefficient (whether it is streamlined or not). Driving habits (whether it often accelerates and decelerates sharply) and road conditions (uphill and downhill, congestion, etc.) affect the working conditions.

This is a very normal phenomenon, because there are uncertain factors in fuel consumption when Nian Gao is used, and it is also related to fuel economy, and it is also related to the speed of the engine, so the fuel consumption of motor vehicles is not the same as that of the car dealer, and there is also a certain error.

Because the car dealer explained the fuel consumption of one of the most basic Bena, and in the actual driving process, the gasoline consumption of the brake and the accelerator is relatively large, so it is different from what the car dealer said to eliminate boredom.

This is the error in practice and theory, and it is also very normal, because when it is actually used, in fact, many parts and components are accompanied by fuel consumption. Luyan Mountain: So sometimes there will be errors.

It is because there is a certain error in the actual use of fuel consumption, and the actual situation is more complicated, so there will be a certain gap.

The fuel consumption of the car:

6L represents the displacement of the engine, that is, the exhaust displacement represents the shape of the cylinder, L4 is an in-line 4-cylinder, and there are V6 and V8 represent the shape of the engine cylinder arrangement like a V-shape. 110 horsepower means that the maximum horsepower of the straight engine is 110 horsepower, that is, how much the maximum power of the engine can be released;

2. Comprehensive fuel consumption refers to the sum of all the average fuel consumption of the car in the urban area, suburbs, mountain roads, and other special environments and road conditions, and finally calculates the comprehensive average fuel consumption. It means 100 kilometers or 90 kilometers of fuel;

3. Look at whether the car consumes fuel, look at its engine displacement, the larger the displacement, the higher the fuel consumption, but now the automobile engine technology is advanced. Cars with a large displacement are also fuel-efficient, which is the benefit of the new generation of turbocharged engines, which can also output more horsepower while saving fuel. Then it depends on the size of the vehicle, the larger the car, the greater the drag coefficient, the more fuel consumption, and the weight of the car, the heavier the car, the more fuel is consumed.

Changhui is like a Japanese car, which is basically fuel-efficient, the reason is that the cost of materials is reduced, cutting corners, the body is lighter, and of course it is fuel-efficient. But the safety factor is not high.

Car displacement is one of the factors that harm fuel consumption, generally speaking, the larger the car displacement, the fuel consumption.

Fuel consumption is also affected by factors such as driving habits, driving roads, vehicle load, tire pressure standards and climate. Fuel consumption displacement of general displacement: 100 kilometers for manual models 4L, 100 kilometers for automatic models; Displacement:

5L for 100 kilometers for manual models, 6-7L for 100 kilometers for automatic models; Displacement: 100 km for manual models, 6-7L for 100 km for automatic models; Displacement: 7L around 100 kilometers for manual models.

The larger the displacement of the car's engine, the greater the horsepower and power, that is, the car is more powerful, and the starting speed, acceleration performance and top speed will be enhanced; Of course, the fuel consumed will also increase accordingly. On the contrary, the displacement is smaller, the performance is correspondingly weakened, but the fuel consumption is reduced; However, the fuel consumption of the car is not only related to the exhaust volume of the engine, but also closely related to the wind resistance design of the car, its own weight, the size and width of the tires, and the driving habits of the driver. Driving always turns, always stepping on the brakes, always driving fast (more than 90 km) or slow (less than 40 km), changing gears in time, pressing the accelerator is not when, and it will naturally cost fuel.

In addition, manual cars are more fuel-efficient than automatic cars, and traffic in the city is congested, so driving in the city is naturally more fuel-efficient than driving on the highway. Turning on the air conditioner will also correspondingly consume the efficiency of the car, especially for small displacement

I believe that there are a lot, the owner of the car is very concerned about the fuel consumption of their car, some cars are very high fuel consumption may be subject to temperature changes, such as in the summer because of the air conditioner, so the fuel consumption will increase, and some cars have not been maintained for a long time will make the car's oil and air filter dirty, resulting in increased resistance of various parts of the engine, at this time more gasoline will be needed. The fuel consumption of the car is mainly caused by the car engine, car license plate, car tires and other driving habits that cannot be used, such as sudden acceleration while driving or frequent braking and hot car for too long, etc., which will increase fuel consumption.

In fact, the fuel consumption of the car is directly related to many factors, such as driving in a big city, because the road conditions are better, so it will be more fuel-efficient, but sometimes you may face traffic jams, at this time, let the accelerator and brake back and forth to switch, it is easy to increase fuel consumption. There are also some car owners will like to put a lot of things in the car, at this time if there are a lot of things in the trunk, and the vehicle is overloaded, it will increase the weight of the car, resulting in an increase in car fuel consumption.

There is a very important thing for the owner when driving, that is, the main function of the spark plug in the engine is to generate an electric spark, so that the engine can start, so that it can drive. When the carbon deposition reaches a certain level, it will affect the ignition time, so that the car fuel can not be fully burned, and a vicious circle will be formed at this time, which will increase the fuel consumption of the car and lead to the fuel consumption of the car.

Finally, with the current oil price getting higher and higher, car owners will pay more attention to some small problems in the process of using the car, so as to avoid spending too much money on gas, which is also because the current oil price is indeed very high.

It is due to the fact that some people drive in the wrong way, so the fuel consumption of the car is very high. It is the way of driving by Hiroka, the speed of driving, and the road of walking. The situation of driving, the speed of the driving Mu Yin faction to carry out the decision to carry the tomb.

The fuel consumption of a car is determined by the size of the displacement, and some cars have a very large displacement, so the fuel consumption is naturally relatively high.

The size of fuel consumption is determined by the capacity of the automobile cylinder, and some cars have a large cylinder capacity and a large amount of fuel injection, so the fuel consumption will be high.

Comprehensive fuel consumption, as the name suggests, a variety of road conditions, highways, urban roads, urban roads, but each car manufacturer, has its own word games, have their own interpretation, the real comprehensive fuel consumption, should be a comprehensive variety of conditions of the road, the amount of fuel consumed, but most of the manufacturers, are not so calculated, so calculated, the value will not look very beautiful, there is no gimmick.

First of all, the habit of driving is very important, there are no bad habits, do not drive a vindictive car, do not drag racing, normal uniform speed, secondly, manual automatic is also different, relatively speaking, manual or slightly less than automatic, if the driving technique is very poor, manual is very fuel-intensive, and there are some details to pay attention to, for example, regardless of spring, summer, autumn and winter, after starting in the morning, hot car, wait for the speed to drop to 800 at the beginning of driving, jog a few kilometers after starting and then speed up, so that the maintenance of the car, on the day of the car, or the fuel consumption in the future, are related, although it will not be obvious fuel saving, but the service life of the car, very important, not urgent refueling, not urgent braking, not overcrowded, this has the most direct relationship with fuel consumption, generally speaking, the actual fuel consumption, most of them are higher than the configuration table written, the estimated manufacturer's comprehensive fuel consumption, that is, highways and town roads, driving at a constant speed, calculating fuel consumption of 100 kilometers, if in the urban area, it will definitely be much higher, start and stop, wait for the red light, drive slowly, so that the fuel consumption is high, it is recommended to drive in the city for a long time, If you have nothing to do, run the highway, or the ring road or something, or you will have a lot of carbon deposits in the engine after driving in the city for a long time.

After talking for a long time, I don't know if you said that your fuel consumption is higher or lower than yours, if it is lower than what is written on the configuration table, then it is not good? It means that you are more fuel-efficient when driving, if it is higher than the configuration table, it doesn't matter, it is normal, most of the city runs like this, if it is much higher, then you have to think about it, either it is a problem of technique, or it is a problem of the car itself.

It's the fuel consumption of the engine at constant speed, which is equivalent to the fuel consumption of running 80 at high speeds, all the time, 80 roads, which is quite flat in this ideal situation.

Therefore, there is a big gap between the fuel consumption on the manual and the actual fuel consumption, just for advertising.

Now all the cars talk about fuel consumption, and it's the unspoken rule that the ideal fuel consumption is not the actual fuel consumption.
