Can ECO mode be left on all the time and is there any damage to the vehicle?

Is it okay to keep the ECO mode on the new car, and will it affect the engine life?

The main principle of ECO mode is not very complicated, mainly in the process of vehicle driving, 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, it is to control the engine speed in a reasonable gear to reduce unnecessary fuel consumption.

Despite its ease of operation and remarkable results, the ECO mode is not effective in certain situations. When the speed exceeds 120 km/h, the eco mode does not work on its own in order to give priority to speed, in other words, if the economic speed is exceeded (usually between 60 and 90 km/h) a lot, then the eco mode will not be able to save fuel. Second, the ECO mode is mainly controlled by the computer while the vehicle is moving, so the ECO function does not work when parking and idling or in N, P and manual modes.

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.

<> long-term use of ECO mode to hurt the car, the Eco mode is to limit the power output of the engine, so as to achieve the effect of energy saving and fuel saving, but long-term use of ECO mode will increase the carbon deposit of the engine.

In ECO mode, the engine will be limited to running in the low speed range, and long-term use of ECO mode will make the engine unable to reach the normal operating temperature and working state, resulting in the gasoline can not be fully burned in the combustion chamber, and over time carbon deposits will occur on the cylinder inner wall, throttle valves, pistons, fuel injectors and other components.

If the carbon deposition is too serious, the vehicle will have insufficient power, increased fuel consumption, engine knocking, abnormal shaking, etc., and even cause the vehicle to fail to start normally.

In fact, in addition to traditional cars, pure electric vehicles also have ECO mode, compared with traditional cars, although pure electric vehicles will not hurt the car for a long time, but it will bring a bad driving experience.

After the ECO mode is turned on, the vehicle will limit the power output of the drive motor, and will also increase the strength of kinetic energy**, which may be difficult to overtake during daily use.

At the same time, when the vehicle slides or brakes, the strong drag caused by kinetic energy ** will seriously affect the ride comfort of the people in the car, so whether it is driving a pure electric car or a traditional oil car, most car owners are actually reluctant to use the ECO mode.
