Can ECO Mode Be Used Frequently?

[MacAnthony]

Cars can frequently use ECO mode, also known as economy mode. When driving in congested urban traffic conditions, turning on ECO mode provides good fuel-saving effects. Under ECO mode operation, engine carbon deposits are roughly similar to those produced under normal operating conditions, so ECO mode can be kept on continuously. The main principle of ECO mode is not complicated. It involves comprehensively analyzing and judging factors that affect fuel consumption during vehicle movement, such as automatic transmission gear position, engine speed, vehicle speed, braking, and transmission oil temperature. The ECU control unit calculates the optimal fuel amount to supply the engine, effectively reducing fuel consumption compared to normal driving mode. Simply put, it controls engine speed with appropriate gear selection to minimize unnecessary fuel consumption. ECO is an abbreviation, with Chinese translations being Ecology (environmental protection), Conservation (energy saving), and Optimization (power). ECO mode is further divided into active ECO driving mode and non-active ECO driving mode. When the ECO indicator light on the dashboard illuminates, it indicates that the vehicle's economy mode is activated. ECO mode comes in active and non-active types. The difference lies in the fact that active ECO mode has its own dedicated button, allowing the driver to choose whether to activate it. When the driver presses the ECO mode switch, the dashboard indicator light comes on, and the vehicle automatically adjusts settings such as throttle opening degree, transmission shift logic, and air conditioning output power. Non-active ECO mode doesn't have a dedicated button. When the dashboard ECO indicator light comes on, it merely serves as 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 vehicles use active ECO driving mode, meaning they have their own switch buttons. Therefore, during daily driving, we can turn on ECO mode. However, it's unnecessary to activate ECO mode when driving at speeds exceeding 120 km/h, during idle parking, in N/P gear, or manual mode—especially when climbing hills. Doing so would fail to demonstrate ECO's fuel-saving characteristics and could affect power performance. Additionally, ECO mode typically becomes ineffective under the following circumstances: When the vehicle speed exceeds 120 kilometers per hour, the car prioritizes speed considerations, causing ECO mode to automatically deactivate. During idle parking or when in N/P gear or manual mode, ECO mode may also become ineffective. When high torque output is required, such as when climbing hills, the engine computer prioritizes ensuring sufficient power to drive the vehicle, and ECO mode will not operate in these situations either.
