What does car eco mean?

[TimothyRose]

Car eco refers to the activation of the energy-saving mode in a vehicle. The main principle of eco is to comprehensively evaluate factors such as automatic transmission gear, engine speed, and transmission oil temperature during driving, and then control the engine speed with appropriate gears. The computer calculates the optimal fuel amount to provide the engine for operation. As an energy-saving mode for cars, eco is mainly divided into active and passive types. The passive type does not have a dedicated button but includes a reminder function. When the vehicle speed exceeds 20 kilometers per hour, eco intelligently assesses the fuel amount and displays it in green on the dashboard. Generally, the eco mode automatically disappears when encountering uphill climbs or acceleration.
