Is the ECO mode of a car a chicken rib or an artifact?

Nowadays, many vehicles are equipped with the fuel-saving function of eco mode, and the fuel-saving effect can be achieved actively by adjusting the work of the engine and gearbox. What are the advantages and disadvantages of starting ECO mode? Is it true that eco mode will cause carbon deposition? Let's analyze it for everyone.

The name ECO is synthesized by ecology (environmental protection), economy (energy saving) and optimization (power). Some manufacturers are also called "ECON", which can be simply understood as the abbreviation of economy.

The basic working principle of ECO mode can be divided into two types, one is passive and the other is active. Passive ECO function is a chicken rib, that is, when the vehicle is driving at a low speed, it will flash the corresponding warning light on its dashboard to remind the driver to control the throttle and not to refuel too much, so as not to waste fuel. For cars, this passive ECO mode has basically been replaced by the active ECO mode.

The active ECO mode can be started directly by the relevant buttons. At this time, the driving computer will control the power system according to the preset mode, mainly by reducing the engine speed and oil content to achieve the purpose of reducing fuel consumption.

After the ECO mode is started, the dynamic performance of the vehicle will be reduced, but the fuel economy can be improved, which can usually achieve the effect of saving fuel 10%, especially for large-displacement vehicles.

However, it should be noted that the engine maintains a relatively low speed after the ECO mode is turned on. Under this working condition, the oil-gas mixture can not be fully burned, which will accelerate the formation of carbon deposits, especially on the accelerator of the engine. Over time, the vehicle will have problems such as reduced power and increased fuel consumption, which will damage the engine and affect its service life.
