Under what circumstances should the car ECO mode be used?

[MacOlivia]

The car ECO mode is turned on and used in urban congested road conditions, and the fuel-saving effect is good after turning on the ECO mode. Under the operation of the ECO mode, the carbon deposits in the engine are basically the same as those produced by the engine in the normal working mode. The main principle of the ECO mode is not complicated. It mainly involves a comprehensive judgment and analysis of factors that affect fuel consumption during vehicle movement, such as automatic transmission gear, engine speed, vehicle speed, braking, and transmission oil temperature. The ECU control unit calculates the appropriate amount of fuel to be supplied to the engine for operation, effectively reducing fuel consumption compared to the normal driving mode. Simply put, it controls the engine speed with reasonable gears to reduce unnecessary fuel consumption. ECO is an abbreviation, and the Chinese translations are Ecology (environmental protection), Conservation (energy saving), and Optimization (power). The Eco mode is also divided into active eco-driving mode and non-active eco-driving mode. When the ECO indicator light on the dashboard lights up, it means the car's economic mode has been activated. The eco mode is divided into active and non-active types. The difference is that the active type has its own button, and the owner can choose whether to turn it on. When the owner presses the eco mode switch, the dashboard indicator light will light up, and the vehicle will automatically start adjusting settings, such as throttle opening, transmission shift logic, and air conditioning output power. The non-active eco mode does not have a dedicated button. When the dashboard eco indicator light is on, it is only a reminder function. The eco mode will automatically evaluate your driving behavior. If your current driving operation achieves the optimal fuel supply, the dashboard will simultaneously display the eco indicator light. Most cars use the active eco-driving mode, which means they have their own switch button. Therefore, during daily driving, we can turn on the eco mode. However, it is not necessary to turn on the eco mode when the speed exceeds 120 mph, during idle parking, in N/P gear, or in manual mode, especially when climbing a hill, as this would not reflect the economic and fuel-saving characteristics of the eco mode. In addition, the eco mode usually fails under the following circumstances: When the vehicle speed exceeds 120 kilometers per hour, the car will consider the speed, and the eco mode will automatically fail. During idle parking or in N/P gear and manual mode, the eco mode may also fail. When a large torque output is required, such as when climbing a hill, the engine computer will prioritize ensuring sufficient power to drive the vehicle, and the eco mode will not work either.
