What is ECO for?

[LeElliot]

ECO is the car's economic driving mode, also known as the economy mode. When the vehicle frequently travels in congested urban road conditions, turning on the ECO mode has a good fuel-saving effect. Under the operation of the ECO mode, the engine carbon deposits are basically similar to those produced under normal operating conditions. The main principle of the ECO mode is not complicated. It mainly involves making comprehensive judgments and analyses during the vehicle's movement regarding factors that affect fuel consumption, 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 provide to the engine for operation, effectively reducing fuel consumption compared to normal driving mode. Simply put, it controls the engine speed with reasonable gears to reduce unnecessary fuel consumption. ECO is an abbreviation, with the Chinese translation being 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 vehicle's economy mode has been activated. The ECO mode is divided into active and non-active types, with the difference being that the active type has its own button, allowing the driver to choose whether to turn it on. When the driver presses the ECO mode switch, the dashboard indicator light immediately lights up, and the vehicle automatically begins to adjust 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 comes on, it is only a reminder function. ECO automatically evaluates 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, the ECO mode can be turned on during daily driving, except when the speed exceeds 120 km/h, during idle parking, in N/P gear, or manual mode, especially when climbing a hill. There is no need to turn on the ECO mode in these situations, as it would not reflect the economic and fuel-saving characteristics of ECO and could even affect power. 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 automatically deactivates. During idle parking or in N/P gear and manual mode, the ECO mode may also fail. When high 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.
