What controls the economic mode and the standard mode of the car, and which is fuel efficient?

The main functional difference between the automobile economic mode and the ordinary mode is that the economic mode is more fuel-efficient than other modes, and is controlled and processed by the ECU of the driving computer. The main differences between economy mode and normal mode driving are as follows: Economy mode is also known as ECO mode.

1. After turning on the economy mode, the ECU of the trip computer will limit the throttle and fuel injector, that is, actively reduce the output power of the engine. Normal mode is normal use, and there will be no restrictions or changes to the throttle and injector.

2. After the economy mode is turned on, the ECU of the driving computer will control the timing of gear switching, and the gearbox response will be slowed down, and it will tend to work under low speed conditions, so as to achieve the effect of fuel saving. The normal mode transmission responds normally, and to put it simply, the Eco is sacrificing the car's power to reduce fuel consumption.

3. After turning on ECO, the output power of the air conditioner will be smaller than that of ordinary mode.

The main principle after the economic mode is not very complicated, mainly in the process of vehicle travel, the automatic transmission gear, engine speed, vehicle speed, braking and transmission oil temperature and other conditions that have an impact on fuel consumption are comprehensively judged and analyzed, and the ECU control unit calculates the optimal fuel amount to provide the engine to do work, so that the fuel consumption is effectively reduced than the ordinary driving mode.

To put it simply, after the economy mode, the engine speed is controlled at a reasonable gear to reduce unnecessary fuel consumption.

There is also an economic model, which is the icon eco mode, which is called the like eco mode. It is just through the ECU to detect whether the driver is lightly stepping on the accelerator when driving, accelerating slowly, decelerating in advance, and judging whether it is fuel-efficient through the accelerator pedal signal, engine speed signal, vehicle speed signal, deceleration and fuel cut signal, etc., so as to light up the ECO green light to praise the owner.

If we kick the throttle while driving, accelerate sharply, or stop and idle, the word eco will not light up! Although it is normal acceleration and deceleration, if it is judged by the system to be fuel-efficient driving, the ECO green light will be on. That is, by turning on and off the ECO lights, we are reminded to maintain good driving habits and save fuel consumption at the same time.

I think that the economic model and the standard mode of the car are controlled by the operation of the engine inside the car. Personally, I think the standard mode is more fuel-efficient, because the economy mode is energy efficient. However, there is a big lack of power, so in order to ensure power, we still use standard mode, which is more fuel-efficient.

Car computer ECU controlled. In urban areas, the economy mode is more fuel-efficient, and in the economy mode, the fuel injector and throttle will be limited to reduce the power output of the engine.

The economic and standard modes of the car are controlled by human beings. I think the economic model is more fuel-efficient.

In general, driving in comfort mode is fineComfort mode is recommended if driving in urban areas, economy mode is recommended if driving at high speeds, switching to economy mode will be more fuel-efficient for the car, and comfort mode is recommended if overtaking on highways.

The economic model is also the ECO model, and the ECO model pursues economy, environmental protection and practicability, which can generally be divided into active type.

There are two types of ECO driving modes and non-active ECO driving modes.

ECO mode is relatively fuel-efficient, but it is recommended not to turn on the ECO during the climbing section, and you can turn it off by yourself if you don't want to use it.

The sport mode can be switched arbitrarily during driving, and the gearbox can be shifted freely, but there will be a certain delay in shifting gears in the sport mode, and the engine will be kept at high rpm for a long time, so that the engine can obtain a very large output power.

Sport mode is usually used when climbing hills and overtaking quickly, and now many models are equipped with sport mode, but it is not recommended to use it under normal driving conditions, and the car's fuel consumption will increase instantaneously in the state of sport mode.

Drivers can choose between four different driving modes: the quiet and quiet "EV mode", the energy-efficient "Eco mode", the stable "Normal mode", and the powerful "Sport mode".

Eco mode will save fuel.

The economic model is generally more fuel-efficient than the standard model, but it may not work in certain situations.

The automobile economic mode is also the ECO energy-saving mode of the car, which is mainly in the process of vehicle travel, the automatic transmission gear, engine speed, vehicle speed, braking and transmission oil temperature and other conditions that have an impact on fuel consumption are comprehensively judged and analyzed, and the ECU control unit calculates the optimal fuel amount to provide the engine to do work, so that the fuel consumption is effectively reduced compared with the ordinary driving mode.

To put it simply, it is to control the engine speed in a reasonable gear to reduce unnecessary fuel consumption.

However, there are certain situations in which the automotive economic model does not work. First, if the economic speed is exceeded (usually between 60 and 90 km/h), then the eco mode will not be able to save fuel.

Second, the ECO mode is mainly controlled by the computer during the vehicle movement, so the ECO function does not work when parking and rolling at a speedy speed or in N, P gear and manual mode.

Thirdly, when it is necessary to overcome a certain resistance and require a large torque output, such as encountering a hill climb, the ECU computer judges that it gives priority to ensuring sufficient power to drive the vehicle, and the ECO mode will not work.

Misconceptions about fuel economy in cars:

Myth 1: Can coasting in neutral save fuel?

In the case of downhill roads or deceleration and coasting, many automatic transmission owners are accustomed to coasting in neutral gear, thinking that this practice is more fuel-efficient, but in fact, it is not. Driving in neutral not only violates traffic bans, but also costs fuel for cars with EFI engines.

At present, the control system of most EFI engines has the function of deceleration and oil reduction or oil cut-off, this kind of car can rely on its own design to achieve the effect of fuel saving at high speed.

Myth 2: Can low-speed and high-gear save fuel?

Driving in low gears consumes more energy, so driving in high gears and low speeds seems to be a habitual behavior for many automatic transmission owners, believing that this practice can achieve the effect of fuel saving. This is unfounded.

Any car will leave the factory with the car's economy speed indicated. Skilled owners often change gears in a way that is imperceptible to the occupants and appears smooth, indicating that they have a very accurate grasp of engine speed and speed. Inaccurate grasp of either of these two factors will result in wasted fuel.

To be clear, driving at high speeds in low gears or driving at low speeds in high gears is a mistake about fuel economy.

Fuel consumption, commonly known as the fuel consumption of a car after driving a kilometer. What we call fuel consumption in daily life generally refers to constant velocity fuel consumption. Constant-speed fuel economy refers to the fuel economy index of the car when driving at constant speed on a good road surface.

Because constant speed driving is a basic working condition for the car to run on the high road, and it is easy to measure, it is widely used without a height ruler. However, due to the fact that the car often accelerates, decelerates, brakes and idles in the actual driving and other working conditions, the constant speed fuel consumption is often low, and the actual fuel consumption is quite different. Some models are calculated and displayed electronically with average and real-time fuel consumption on the car's computer.

If not, fuel consumption can also be roughly calculated by the simple method.

The economic mode of the car, also called ECO mode, is to modify the throttle opening through the vehicle's computer to correct the driver's irregular operation, so as to achieve the most standard fuel-saving mode, while the sports mode is to increase the speed range of the shift, increase the torque of the engine, and reach the maximum power, the specific operation steps of using these two modes are as follows:

1. Press the brake pedal of the car.

2. Press the car's one-button start button.

3. The instrument of the car lights up, and the power supply of the whole car is turned on.

4. Put the automatic transmission in S gear to turn on the sport mode.

5. Press the ECO button to turn on the economic mode of the vehicle.

Compared with the comfort mode and the standard mode, the most prominent thing in the economy mode is that it is fuel-efficient.

The economic model is also called ECO, and some manufacturers will call it ECON. The main function of the economic mode is that when driving, it can deal with the engine speed, vehicle speed, gearbox gear, etc., which have an impact on the fuel consumption of the vehicle, and the on-board computer will calculate how much fuel the vehicle needs to be able to play the required performance, and finally provide it to the engine for work.

After the vehicle is turned on eco mode, the response efficiency of the power output is reduced a lot, and there are many unnecessary fuel injections are also reduced. This throttle response will not be so fast, and when you press the throttle deeply, the power will be slower, which can effectively save fuel.

When the vehicle is in comfort mode, the suspension will be softer, the steering wheel will be lighter, steering will be more convenient, and the engine speed will be kept lower.

In standard mode, the driving plan used is in the most standard condition, and the fuel injectors, throttle valves, etc. in the car will not change in any way. It will have a certain fuel saving capacity as well as a certain power.

The speed of the vehicle in the economy mode is relatively low, and it is rumored on the Internet that turning on the economy mode for a long time can easily cause carbon accumulation in the car. In fact, this is wrong, the economic model will not affect the carbon deposit of the car. Carbon deposits are caused by impurities that cannot be completely burned when gasoline enters the combustion chamber and thus adheres to the engine.

Ask. In urban areas, which is better, the economic model or the standard model? Is there a big difference in fuel consumption?

Thanks for asking. Which is better, the economic model or the standard model? Is there a big difference in fuel consumption?

Thank you My habit is: when driving in the city, as long as it is not when starting and overtaking, I like to drive in economic mode, saying that it can save 20% of fuel. But if you want to overtake the cargo and climb the hill, you still don't want to use the economic mode, just give oil, and the power will not rise.

In the smooth stage of the car, it is quite fuel-efficient to use the economic model. It's mostly based on personal habits. The economic mode is not suitable for the congested road, and the speed of the congested road does not reach the average speed condition, which not only can not save fuel but also weakens the engine power output.

The so-called economic mode actually means that the gearbox controls the engine, and when the engine reaches a certain speed, it automatically switches into gear, so as to avoid the loss of fuel consumption caused by high speed, and also reduce the amount of fuel injected by the fuel injector. Therefore, the economic model can indeed save a lot of fuel under the condition of medium and high-speed transportation. However, due to the main urban area due to parking and blockage, this time open the eco mode, because the engine is more meat in this mode, so everyone will increase the intensity of stepping on the accelerator, resulting in an increase in the amount of fuel injection from the fuel injector, at this time the engine has just entered the second gear and will downshift and stop, so the fuel consumption of the eco mode in the case of traffic jam or slow down is greater than the normal mode.

Therefore, because the eco mode will force the gearbox to shift at speed, so in the case of traffic jams and low speeds for a long time, it will increase the carbon deposition of the engine and throttle, and the gains outweigh the losses, so it is recommended that you try not to turn on the eco mode in the case of traffic jams.

Economic mode (ECO), Xiangqing Zhaozhao sports mode (sport) has a special control switch to use, the economic mode is to correct the driver's operation through the electronic control system, to achieve the purpose of fuel saving, the sports mode is to increase the speed range of the vehicle shift, improve the dynamics of the vehicle, the specific operation steps are as follows:

1. Step on the brakes of the car and guess the land pedal.

2. Press the car's one-button start button.

3. The instrument lights up, and the power supply of the whole car is turned on.

4. Press the button of Economy Mode or Sport Mode located in the car.

5. At this time, the car will enter the economic mode or the sports mode.
