Is ECO on or off to save fuel? What's your opinion?

ECO mode is the optimization of ecology, economy, environmental protection and energy saving, and its core purpose is to reduce exhaust emissions by controlling the consumption of gasoline and diesel. Fuel-saving mode is a fixed mode, which is a fuel-saving method for everyone formulated by two groups, those who know how to drive and those who don't. A simple understanding of ECO mode is to limit the shift frequency of output power, and the essence of limiting output power is to limit speed ratio. Assuming that the waiting speed is accelerated to 60km, the shift frequency of ECO mode is about:

Different forward gear ratios are different, the larger the gear, the smaller the torque, but it can also effectively reduce the engine speed ratio when it is fast; The lower the speed ratio, the lower the output power. Because the output power = speed ratio * (torque /9549), the lower the speed ratio, the lower the working frequency of the engine and the lower the fuel consumption, but at the same time, the reduction of output power will obviously reduce the driving force. In normal mode, when the vehicle speed is accelerated to 60km/h, the forward gear can be controlled at 3~4, and the speed ratio of each gear is controlled at 3000 rpm, which not only accelerates quickly, but also does not need frequent upshifts. When the target speed is reached, the forward gear will be upgraded step by step at a constant cruise speed, and this acceleration will not significantly increase fuel consumption in the whole process.

After we start the environmental protection and energy-saving mode, our patient friends may find that in this mode, when everyone steps on the accelerator, the response of the vehicle will be slower, which is not as easy as in our normal mode, so the engine of the car will follow the angle of the accelerator pedal and derive the driving force. As long as we start the environmental protection and energy saving mode, their vehicles will actually limit their engine power output, in other words, their vehicles will limit the throttle opening.

Scientifically speaking, cars equipped with ECO are fuel-efficient, but in our specific driving practice, it is not certain that ECO is fuel-efficient. The key factor of whether a car can save fuel is the driver's driving habits, that is, daily life. Under the same road conditions, different drivers give different fuel consumption.
