The same 2 0 displacement car, why is the fuel consumption different? Why?

I believe that many car owners have such a doubt, the same displacement of the car, but the fuel consumption of these two cars is not the same. This phenomenon is due to the fact that the driving behavior of the owner is related to the working condition of the car. The reason lies in two aspects, one is that the driver's habit of slamming on the brake and slamming on the accelerator will lead to an increase in fuel consumption; The second aspect is that the owner does not maintain the car regularly.

caused by the throttle of the car.

and spark plug carbon deposition is serious, which will also lead to the same displacement of the car under different working conditions, then the fuel consumption is not the same.

First, the driving habits of the owner will lead to the same displacement of the car fuel consumption is different.

For the current car owners, the fuel consumption of the car is a problem that the car owner is most concerned about, because fuel consumption directly affects the cost of the owner. The reason why the fuel consumption of the car with the same displacement will be different, the biggest factor is because of the driver's own driving behavior, if a car owner drives the car violently, and at the same time likes to slam on the brakes and slam on the accelerator This driving habit, then it will lead to a direct increase in the fuel consumption of the car, so the fuel consumption of the car with the same displacement is inconsistent with the driving behavior of the owner has a great relationship. <>

Second, the different working conditions of the car will also lead to the inconsistency of the fuel consumption of the car.

The working condition of the car has a great impact on the fuel consumption of the car, and it also has a certain relationship with the driver's driving safety. The so-called different car conditions are often caused by the different working conditions of the throttle and spark plug of the car, that is to say, the owner is not so concerned about the maintenance of the car, which also leads to the serious carbon deposition of the throttle valve and spark plug of the car, so that the serious carbon deposition of these components will directly lead to the increase of fuel consumption of the car, so the car with the same displacement has a direct relationship with the working condition of the car. <>

3. Summary. In general, the car has entered everyone's life, traversed everyone's traffic, but the same displacement of the car fuel consumption is often inconsistent because of the owner's non-standard driving behavior and the working conditions of the car itself, so the owner must maintain a good driving habit in the process of driving, and at the same time to maintain the car regularly, so as to protect the working condition of the car and reduce the fuel consumption of the car. <>

The main reason lies in the technical and related construction problems of the engine, if the technical standard of the engine is not up to standard, it will lead to a little more fuel consumption.

Fuel consumption is related to many aspects, and the same displacement is just a common ratio, which will not be too bad. The key to influencing fuel consumption is the engine with several cylinders and the transmission at several speeds. To put it simply, Bora 1

6 and Corolla fuel consumption is two worse, because the Corolla body is light, and the transmission is more advanced. To put it simply, this question is equivalent to why the height of the same 8-year-old child is different, because there are too many factors that lead to differences. And the same car, the manual transmission is more fuel-efficient than the automatic transmission, which is a popular concept based on the old gearbox in the past.

It is related to the engine, and the fuel consumption of different engines is definitely different, which is very normal.

I think the fuel consumption of cars with the same displacement is not about the same, although some cars have a large displacement, but the fuel consumption is relatively small; I think there is a very big difference, how to operate in a different environment, the operator's action is different, or the engine and some parts in it are different, it will lead to different fuel consumption.

Of course not, if the displacement is the same, the fuel consumption of the car will be affected by other factors, such as the condition of the car, and the technology of the engine, there are certain differences.

It's not that the displacement is the same, the fuel consumption is the same; This side is very large, because fuel consumption is not only to look at the displacement, but also to see the quality of the car, the habits of the drivers.

If it is the same model, but the power system is different, the difference between automatic and manual fuel consumption per 100 kilometers is about a liter, and if it is a different model, there is no accurate comparison.

Fuel consumption per 100 kilometers refers to the fuel consumption of a vehicle driving 100 kilometers on the road at a certain speed. It is a theoretical indicator of the vehicle. 100 kilometers of fuel consumption is the manufacturer in the objective environment, with the vehicle chassis installed in the dynamometer measured value measured into the speed parameters, and then specify the speed to drive, calculate the model of the theoretical experiment 100 kilometers fuel consumption data.

Since most vehicles are close to economic speed at 90 km/h, most of the published theoretical fuel consumption is usually 90 km/h per 100 km/h. (The exhaust gas volume is determined by analyzing the carbon content in the exhaust gas by exhaust gas analyzer and carbon balance method).

Fuel consumption and displacement.

Although fuel consumption has a relationship with displacement, this relationship is not absolute. A large cylinder volume (displacement) can accommodate more combustible mixtures (air fuel), so when all other conditions are the same, it must be that the engine with a larger cylinder volume (displacement) has better fuel consumption and is higher.

Fuel consumption and speed.

When driving a car daily, the speed range is generally between 1000-3000 rpm, and the ultimate speed of an ordinary family car is only about 6000 rpm.

Fuel consumption and driving habits.

Off-road car owners who like to rush to the sand like to drive in the desert, and they must go to refuel after a while, not that large-displacement cars will definitely cost fuel, but everyone's driving methods have a certain relationship with the geographical environment.

Fuel consumption and vehicle modifications.

Widening and enlarging tires increases the friction of tires, which is equivalent to increasing the load of the car, which directly increases the fuel consumption of the car. At the same time, some car owners will be car rear wing, car surround and so on together modification, increase the tail wing undoubtedly increase the car resistance, the car at low speed when the tail wing does not work at all, can only increase the driving resistance to increase the vehicle load, will inevitably lead to fuel consumption rise.

Fuel consumption per hour.

100 kilometers of fuel consumption is an indicator of the vehicle, power fuel consumption is a specification of formatting statistics, the slower the vehicle in the economic speed, the more fuel consumption per 100 kilometers, more than the economic speed is the opposite, if the engine speed is controlled within the same safe speed, regardless of the speed of the vehicle, the fuel consumption per hour is the same, when calculating fuel consumption on highways and engineering transportation, it is not suitable to use the first two specifications, and the calculation of fuel consumption per hour is more accurate. Fuel consumption per hour is calculated by formula: fuel consumption per 100 kilometers 100 * limit * limit speed is the maximum safe speed).

The displacement and fuel consumption of the car depend on the specific use, if the configuration is the same rating, then the difference is about 15%.

Fuel consumption generation:

1. Generally speaking, the larger the displacement, the higher the fuel consumption per 100 kilometers. But there can be no formula between the two, at least not the driver's handling.

2. However, the following factors can be used as a relatively large weight as a reference for fuel consumption: displacement; curb weight; Full load mass; Actual working conditions of the engine**speed, output torque); Road conditions can be reflected by the real-time parameters of the engine.

3. There are many others, such as wind resistance (which is affected when the speed is very high), tires, etc.

4. But the most difficult to quantify is not only the human driving factor, but also the assembly process, which is the key to testing the comprehensive strength of the manufacturer.

5. The results of the same bearing, the same fit, and different assembly methods are very different, and the final results of process control are also very different.

Look at the tuning method, for example, the fuel consumption of four-valve and two-valve engines like the old Sutar is about 2L.

Similar to the Mazda M86 and the MZR, the difference is about 1L.

Similar to Fox and the gap is around 3L.

Depending on the specific application, the difference between the same configuration (weight, load, engine specification, etc.) is about 15%; However, if there is a lot of load on the case, it will cost more fuel.

If the model is the same, the engine suction and in-cylinder combustion technology are similar, generally about 8 to 9 at high speed, and 10 to 11 in urban areas. There are about 7 expressways and 8 to 9 in urban areas.

Hehe. Comprehensive vehicle weight, engine technology, driving technology, matching. The answer may not be the same. The Cruze's are more fuel-expensive than many of them.

But generally speaking, it is about 2 taels of oil more.

It can be worse than 2, this is only one-sided, it mainly depends on the weight of your car.

The gap is not very large, more than 100 kilometers and a few tenths of oil. Below is the approximate fuel consumption and displacement.

Displacement, 60 percent of high-speed, 40 percent of urban area, current comprehensive fuel consumption, pure urban stop-and-go more than 10 oil.

Displacement, I look at my friend's comprehensive fuel consumption, but the urban area is estimated to account for 10.

Usually the displacement is large, and the energy released by the engine per unit time (that is, the chemical energy of the fuel is converted into mechanical energy) is large, that is, the "power" is good, just like a teenager boy is of course more efficient than a healthy adult. So those off-road vehicles and sports cars usually have a relatively large displacement.
